How to install Java JDK Java Development Kit on mac. In Mac OSX 10.5 or later, Apple recommends to set the $JAVAHOME variable to /usr/libexec/javahome, jus. Java and the Mac OS X Terminal. Machine: wayne$ java -version java version '1.6.026' Java(TM) SE Runtime Environment (build 1.6.026-b03-3). Download Java for OS X directly from Oracle. Get the latest version If an app or webpage you want to use asks you to install Java software, you can download the current version of Java for OS X directly from Oracle's website.

Mac OS X Yosemite (and the newer versions) are having a later version of Java Runtime (SE 8.0). However, Java Runtime is not backward compatible. So, even when the operating system have installed Java Runtime 8, it will NOT run apps that rely on Java Runtime 6. Java Standard Edition (SE) is a free software bundle that provides the Java Runtime Environment and the libraries and components you need to display a wide range of programs and Web content on 32.

Mac OS Runtime for Java (MRJ, originally Macintosh Runtime for Java) was Apple's proprietary virtual machine for Java-based applications in the classic Mac OS (i.e. versions prior to Mac OS X). Both a runtime environment and a software development kit (SDK) are available.

The runtime environment includes a JIT compiler developed by Symantec, the standard Java class library from Sun, additional classes providing Macintosh-specific functionality, and the Apple Applet Runner (a lightweight application for running Java applets without the overhead of a web browser). A number of web browsers could use MRJ to run Java applets in web pages, including MicrosoftInternet Explorer, iCab and HotJava.

The SDK includes ports of most of the tools from Sun's Java Development Kit (in the form of MPW tools and Macintosh applications), additional tools for packaging Java applications as double-clickable Macintosh applications, libraries for Macintosh-specific functionality, and documentation for the MRJ-specific classes and tools.

MRJ v2.2.5 was compatible with Sun's Java Development Kit version 1.1.8.^[1]

Since the transition to Mac OS X, Apple has discontinued MRJ and instead maintains and distributes a port of Oracle'sHotSpot Java virtual machine.^{[citation needed]}

Implementations[edit]

• Java 1.0.2 with Mac OS Runtime for Java v 1.5.1 [1]
• Java 2.2.6 with Mac OS Runtime for Java v 2.2.6 [2]

Java and the Mac OS X Terminal

This page is obsolete.

This document instructs you on how to use the Mac OS X Terminal with Java.

You will use the Java compiler javac to compile your Java programs andthe Java interpreter java to run them.To verify that Apple's implementation of Java 2 Standard Edition (Java SE 6) isalready installed:

• Run Software Update.
• Run Applications/Utilities/Java/Java Preferencesand verify that the Java SE 6 - 64-bit entry is checked andfirst in the list; if not, drag to change the preferred order.

You will type commands in an application called the Terminal.

• Open a terminal window. You can find this underGo -> Applications -> Utilities. Drag the Terminal to your dock sinceyou will be using it frequently.
• You should now have a Terminal window somewhere on the screen.It will have a prompt that looks something like:

  To check that you are running the right version of Java, typethe commands in boldface below. You should see something similar to the information printed below. The importantpart is that it says 1.6 or 1.5 (and not 1.4).

  Then type

  Since you will be using the Terminal frequently, you may want tocustomize the default window settings (e.g., Monaco 13pt font with antialiasing).

You will use the javac command to convert your Java program into a form moreamenable for execution on a computer.

• From the Terminal, navigate to the directory containing your .javafiles, say ~wayne/introcs/hello, by typing the cd commandbelow.

  Assuming the file, say HelloWorld.java is in the currentworking directory, type the javac command below to compile it.

  If everything went well, you should see no error messages.

You will use the java command to execute your program.

• From the Terminal, type the java command below.If all goes well, you should see the output of the program -Hello, World.

If your program gets stuck in an infinite loop, type Ctrl-c to break out.

If you are entering input from the keyboard, you can signifyto your program that there is no more data by typingCtrl-d for EOF (end of file).You should type this character on its own line.

Java 8 For Mac

When I try to run java I get: Exception in thread 'main' java.lang.NoClassDefFoundError.First, be sure that HelloWorld.class is in the current directory.Be sure to type java HelloWorld without a trailing .classor .java.If this was not your problem, it's possiblethat your CLASSPATH was set by some other program so that it no longerincludes the current working directory.Try running your program with the command line

I get the error 'class file has wrong version 50.0, should be 49.0' when I compilefrom the Terminal. What does this mean?It's probably because DrJava is configured to use Java 6.0 and and your Terminal is configured to use Java 5.0.To change the default version of Java in your Terminal, launchJava Preferencest. Drag the Java SE 6 - 64-bit entryto appear first.

How do I get the menu to display at the topof the screen instead of at the top of the frame?Execute with java -Dapple.laf.useScreenMenuBar=true
