Experience your favorite iPad apps now on your Mac. With Mac Catalyst, developers can easily create Mac apps from the iPad apps you already know and love. They run natively alongside your existing Mac apps so you can drag and drop content between them. They take full advantage of the larger screen and powerful architecture of your Mac. Java is one of the most vital components of any browser, and it pretty much applies to Mac too. Many of the high-end features and commonly used tools are built on Java platform. Many enthusiasts say that it can be a threat regarding it as a malware vector; to be very practical, it is one of the.
iPadOS features additional technologies that take advantage of the unique functionality of iPad using the iOS SDK. With iPadOS, your iPad apps can now deliver multiwindow experiences, add full drawing experiences for Apple Pencil, and contribute fonts for systemwide use.
Multitasking
With Multitasking capabilities such as Slide Over, Split View, and Picture in Picture, users can quickly switch from one app to another with intuitive gestures.
Multiple Windows
In iPadOS, apps that support Drag and Drop can also support multiple windows. For example, users of a document creation app can work on several documents at once, use the app in Split View or in multiple spaces, and even work with multiple apps in Slide Over.
Drag and Drop
With multitouch APIs, your apps can let users quickly move text, images, and files from one app to another. Support Drag and Drop in your apps to let users move content in a way that feels natural.
PencilKit
Apple Pencil delivers pixel-perfect precision and industry-leading low latency, making it great for drawing, sketching, coloring, taking notes, marking up email, and more. Your apps can take advantage of Apple Pencil, which features an intuitive touch surface that supports double-tap gestures. And with PencilKit, the new feature-rich drawing and annotation framework, you can now easily add a full drawing experience to your app — with access to a canvas, responsive inks, a rich tool palette, and a drawing model on iPadOS.
Files and Folders
Files now supports USB drives, SD cards, and file servers. And host of new features like Column View, Quick Actions and local storage make Files even more powerful.
Fonts
With iPadOS, your app can contribute fonts for systemwide use and use other contributed fonts, offered through the new font picker interface. And new system UI fonts are now available for use in your app.
Machine Learning
With on-device model training and a gallery of curated models, there’s never been a better time to take advantage of machine learning. Core ML seamlessly takes advantage of the CPU, GPU, and Neural Engine to provide maximum performance and efficiency, and lets you integrate the latest cutting-edge models into your apps. The Create ML app lets you build, train, and deploy machine learning models with no machine learning expertise required.
Augmented Reality
ARKit delivers an incredible awareness of people with the ability to integrate human movement into your app, the People Occlusion feature that lets AR content realistically pass behind and in front of people in the real world, and much more. RealityKit — Apple’s rendering, animation, physics, and audio engine — powers Reality Composer and can power your own AR apps, allowing you to seamlessly integrate virtual objects into the real world.

Desktop-class Browsing with Safari
Safari on iPad supports the latest web standards and automatically adapts websites and web apps to touch, delivering a rich browsing experience with blazing-fast performance, industry-leading security, and modern desktop features. Your site or embedded WebView can take advantage of powerful new features and coding best practices to deliver a best-in class user experience for iPad.
Building for iPad Pro
iPad Pro lets you deliver faster, more responsive experiences like never before. The all-screen design goes from edge to edge. Face ID works seamlessly in portrait or landscape. The A12X Bionic chip outperforms the vast majority of portable PCs, runs pro apps, and enables stunning augmented reality experiences. And with support for accessories like the second-generation Apple Pencil and Smart Keyboard Folio, iPad Pro represents the biggest change to iPad ever.
Face ID
This secure way to unlock, authenticate, and pay lets users quickly access your app with just a glance. The TrueDepth camera projects and analyzes more than 30,000 invisible dots to create a facial map that is encrypted and protected by the Secure Enclave on the device.
For details on user authentication, see the Human Interface Guidelines.
A12X Bionic
The A12X Bionic chip with the Neural Engine is the smartest, most powerful chip we’ve ever made, and it’s been designed specifically for iPad Pro. The A12X Bionic delivers faster CPU performance than the majority of portable PCs. The Apple-designed 7-core GPU, along with architectural enhancements and memory compression enable the GPU to perform up to 2x faster. And the 8-core Neural Engine, which runs five trillion operations per second, is dedicated to highly efficient, powerful machine learning, enabling all-new experiences.
UI Optimization
Take advantage of the all-screen design of the 11-inch iPad Pro and 12.9-inch iPad Pro (3rd generation) by building your app with the iOS 12.1 SDK or later and making sure it appears correctly with the display’s rounded corners and home indicator.
Run and Test in Simulator. Make sure your apps take advantage of the edge-to-edge Liquid Retina display by respecting safe areas and supporting adaptive layouts. Read the updated Human Interface Guidelines, download the latest version of Xcode, and test your app in Simulator.
Enable full screen native resolution. Your app will run in Full Screen Display Mode on iPad Pro if your project’s base SDK is set to iOS 12.1 or later and you have a Launch Storyboard.
Verify all parts of your app. Make sure that your UI displays correctly and no elements are mispositioned, overlapping, incorrectly scaled, or clipped. If you discover issues, use the safe area guides and layout margins to correctly position UI elements.
Bring Your iPad App to Mac
Get a huge head start on creating a native Mac app based on your existing iPad app. Your Mac and iPad apps share the same project and source code, so any changes you make translate to both platforms. And your newly created Mac app runs natively, utilizing the same frameworks, resources, and even runtime environment as apps built just for Mac.
Sidecar on macOS Catalina
Users running macOS Catalina can use iPad as a secondary display alongside Mac and draw with Apple Pencil on iPad. There’s no need to make any adjustments to Mac apps — they just work.
This DrJava-based Java programming environment is no longer being supported(because DrJava in no longer being actively developed and DrJava is incompatible with Java 11).It has been replaced by the following IntelliJ-based programming environment forMac OS X.
This document instructs you on how to set up our Java programming environment for your Mac OS X computer. It also provides a step-by-step guide for creating, compiling, and executing a Java program using either DrJava or the Terminal.All of the software used is freely available.
You will need an Intel-based Mac runningMac OS X 10.8 (Mountain Lion) to Mac OS X 10.13 (High Sierra).
You can defer steps 4–6 until Section 1.5 of the textbook.
Our installer downloads, installs, and configures the Java programming environment you will be using, including DrJava, and the standard libraries from our textbook.
- Log in to the user account in which you will be programming.Your account must have Administrator privileges (with a non-blank password)and you must be connected to the Internet.
- Install Oracle's implementation of the Java Platform, Standard Edition Development Kit (JDK 8).Do not install either JDK 9 or JDK 10, as they are currently incompatible with DrJava.
- Browse toJava SE Development Kit 8u171.In the first table, check Accept License Agreementand the click jdk-8u171-macosx-x64.dmg,which corresponds to the entry for Mac OS X.The exact verison 8u171 is not essential.
- Double click the downloaded file jdk-8u171-macosx-x64.dmg to begin the installation.Enter your OS X password when prompted.We recommend all of the default options.
- Delete jdk-8u171-macosx-x64.dmg.
- To install,
- Download introcs.zip to the Desktop;double-click it to unzip (if necessary). This creates introcs.app. Security and Privacy -> General -> Allow applications downloaded from: Anywhere.
To enable this option, you may need to click the lock in the lower left-hand corner(and type your password when prompted).-->
- Double-click introcs.app to perform the installation.If you receive a warning that introcs.app is an applicationdownloaded from the Internet, click Open.
- Enter your OS X password when prompted.
- Download introcs.zip to the Desktop;double-click it to unzip (if necessary). This creates introcs.app. Security and Privacy -> General -> Allow applications downloaded from: Anywhere.
- If the installation succeeds, you will see the following:
- A Terminal window containing approximately thisexecution log.
- A Standard Drawing window containing a red bullseye and a textbook graphic.
- Delete introcs.zip and introcs.app.
Now you are ready to write your first Java program.You will develop your Java programs in an application called DrJava.DrJava features many specialized programming tools including syntax highlighting,bracket matching, auto indenting, and line numbering.
- The installer creates a shortcut to DrJava on the desktop.Double-click it to launch DrJava.If you receive a warning about incoming network connections,click Allow.
- In the main DrJava window, type the Java programHelloWorld.java exactly as it appears below. If you omit even a semicolon, the program won't work. As you type, DrJava does the indenting for you.
- Finally, click the Save button to save the file, using the name HelloWorld.java.The filename is case sensitive and must exactly match the name of theclass in the Java program.
It is now time to convert your Java program into a form more amenable for execution on a computer. To do this, click the Compile button.If all goes well, you should see the following message in the Compiler Outputpane at the bottom:
If DrJava complains in some way, you mistyped something.Check your program carefully, using the error messages in the Compiler Output paneas a guide.
Now it is time to run your program. This is the fun part.
- Type the following in the Interactions pane at the bottom.By convention, we highlight the text you type in boldface. If all goes well, you should see the following message:
- You may need to repeat this edit–compile–execute cycle a few times before it works. Ask for help if you can't see the mistake.
The command-line provides capabilities beyond those available in DrJava,including redirection and piping.You will type commands in an application called the Terminal.
- The installer creates a shortcut on the desktop to the Terminal.Double-click it to launch the Terminal.You should see something like:The ~ is shorthand for your home directory /Users/<username>.
- To confirm that the Java compiler is installed,type the command in boldface below and check that the results match:It's important that you see the number 1.8for the Java version number, but the rest is not critical.
- To confirm that you the Java interpreter is installed, typethe command in boldface below and check that the results match:Again, it's important that you see the number 1.8for the Java version number, but the rest is not critical.
You will use the javac command to convert your Java program into a form more amenable for execution on a computer.
- From the Terminal, navigate to the directory containing HelloWorld.java,say ~/Desktop/hello,by typing the cd (change directory) commands below:The ~ is shorthand for /Users/<username>.
- Compile it by typing the javac command below:Assuming the file HelloWorld.java is in the current working directory,you should see no error messages.
- To make our textbook standard libraries accessible to Java,use the command javac-introcs instead.For example,BouncingBall.javais a program that uses our standard drawing library.After downloading the file to the current directory,you can compile it with the following command:
You will use the java command to execute your program.
- From the Terminal, type the java command below.You should see the output of the program.
- To make our textbook standard libraries accessible to Java,use the command java-introcs instead. For example, to executeBouncingBall.java(assuming you downloaded and compiled it in the previous step), type the following command:
How long should the installer take?Once downloaded, the Oracle Java installer should take about 10 seconds and the introcs.app installer should take about 20 seconds. If you have virus detection software running (such as McAfee Endpoint), each could take 5–10 minutes (or more).
The installer didn't work on my machine. What should I do?Check out the following three Q+As. If these don't resolve the issue,please contact a staff member to identify what went wrong.
When I run the installer, the terminal window just waits after asking for a password.But, I don't even have a password-enabled account.You must have a non-blank password. Here are instructions forresetting a user's password.
When I run the installer, I get the error message'bash: /Volumes/Macintosh: No such file or directory'.Your user account and OS must be on the same volume.
When I run the installer, I get an error like bash: /private/var/folders/70/n8stth1d1x33hrw8n07kf1280000gn/T/AppTranslocation/45FC25B7-17E3-46DF-AC27-9A7EF56DDFD3/d/algs4.app/Contents/Resources/launcher.sh: No such file or directory.What should I do? This is likely due to OS X Sierra path randomization.Use the Finder to move introcs.app to some other folder and try again.
What does the installer do?In short, it downloads, installs, and configures Checkstyle, Findbugs, and DrJava, and the textbook standard libraries.Here is a more detailed list:
- Checks that Java is installed.
- Downloads the textbook standard libraries fromstdlib.jar.
- Downloads the Java wrapper scriptsjavac-introcs andjava-introcs.
- Downloads and installsFindbugs 3.0.1from findbugs.zip.Downloads our findbugs configuration file findbugs.xml and wrapper script findbugs-introcs.
- Downloads and installsPMD 5.8.1from pmd.zip.Downloads our PMD configuration file pmd.xmland wrapper script pmd-introcs.
- Downloads and installsCheckstyle 8.2from checkstyle.zip.Downloads our checkstyle configuration file checkstyle-introcs.xml and wrapper script checkstyle-introcs.
- Downloads and installs the latest stable version ofDrJava,from DrJava.zip.Creates a shortcut to DrJava on the Desktop.Downloads and installs the DrJava configuration file fromdrjava-config.txtto /Users/<username>/.drjava.Note that this will overwrite any existing .drjava configuration file.
- Tests that the installation succeeded by compiling and executing TestIntroCS.java.
Why does the installer need my password?The installer copies files into /usr/local/bin and/usr/local/introcs,which require superuser privileges.
How do I completely uninstall introcs.app?
- Delete the directory /usr/local/introcs.
- To uninstall DrJava, delete the following two files:
- /Applications/DrJava.app.
- /Users/<username>/.drjava.
- To uninstall the Java, Checkstyle, and Findbugs wrapper scripts,delete the following files:
- /usr/local/bin/javac-introcs
- /usr/local/bin/java-introcs
- /usr/local/bin/findbugs-introcs
- /usr/local/bin/pmd-introcs
- /usr/local/bin/checkstyle-introcs
- Delete the shortcut to DrJava and Terminal on the Desktop.
What happens if I re-run the installer?It will re-download, install, and configure Checkstyle, Findbugs, DrJava, and our textbook libraries.
Can I use a different version of Java?Any version of Java 8 (either Oracle or OpenJDK) should work fine.Note that DrJava does not currently work with Java 9.
I have both Java 8 and Java 9 installed, but the default version is Java 9. How doI change the default version back to Java 8?To disable Java 9, type the following commands in the Terminal:
You should still be able to use Java 9 by specifying the full path tojavac and java
, e.g.,/Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk/Contents/Home/bin/javac.Why I try to run DrJava, I get the following error message. How should I proceed?
Are you sure that you are using the version of DrJava that was installedby our auto-installer (and not downloaded from the DrJava website)?We suggest deleting any older versions of DrJava and using the one that the auto-installer copied to theJava Runtime For Mac
/Applications directory.Java For Mac 10.7
Can I use a different IDE? Yes you can use another IDE (such as Eclipse) butyou will have to configure the IDE properties yourself (such as the classpath). Reset Interactions.From the Terminal, type Ctrl-c.
To put your game back to how it was (not working presumably if you had to just do that step!), navigate through to the Electronic Arts folder again and trash the Sims 3 folder the game just recreated. Sims 3 for mac air. Put your old folder, the one you moved to the desktop, back in it’s place. You will need to move back your CC/Saves/Downloads/Mods etc. Bit by bit from the folder you moved out to the newly generated folder to work out where the problem lies.
When using standard input, how do I signify that there is no more data?If you are typing input in the Terminal or DrJava, type Ctrl-d on its own line.
I successfully compiled HelloWorld.java with javac, but, when I execute,I get the error message'Exception in thread 'main' java.lang.NoClassDefFoundError: HelloWorld'.What am I doing wrong?First, verify that the file HelloWorld.class is in the current directory.Be sure to type java HelloWorld without a trailing .classor .java.-->
When I compile or execute a program in Terminal that uses thetextbook standard library, I get an error that it cannot find the library. How can I fix this?Use the wrapper scripts javac-introcs and java-introcs,which add stdlib.jar to the Java classpath.
Which shell should I use in the Terminal?Bash is the default shell in Mac OS X, but feel free to usewhichever one you prefer.
Where can I learn more about the command line?Here is a short tutorial on thecommand line.
