So, to make the JDK work, you have to modify the PATH and CLASSPATH environment variables on your system, so that Windows will be able to find javac and java, and so that javac and java will be able to find all of the necessary Java classes. CLASSPATH is a list of folders, separated by semicolons, in which the Java compiler or virtual machine will look for a Java class whenever it's trying to find one. This is the job of the CLASSPATH environment variable. Similarly, whenever the Java compiler or Java virtual machine need to be able to use a Java class (such as when you import a class from the Java library), the compiler or virtual machine needs to be able to know where to find it. PATH is a list of folders, separated by semicolons, in which Windows will look for a program whenever you try to execute one. This is the job of the PATH environment variable. But there's a catch: Windows has to know where it can find these programs. You can execute programs from a Command Prompt by simply typing their names, such as javac or java.
The (not all that) hard part: PATH and CLASSPATH The reason for this suggestion is that the next steps in the installation process will be simpler if the folder you choose has a shorter name that, importantly, has no spaces in it.

(And, of course, you can feel free to install to a drive other than C:, if you have more than one.) I suggest changing it to the following folder instead: When asked what folder you should install the JDK into, the default will be: However, after running the installation program, you still won't be able to execute javac or java, without making a couple of modifications "under the hood" of your system.
The JDK includes an installation program, which places all of the files into the appropriate places and sets up some shortcuts for you. It's best to download the JDK and not the JRE - the difference is that the JDK includes a Java compiler ( javac) and a variety of other tools for building and packaging-up Java programs, while the JRE (the Java Runtime Environment) includes only the necessary tools to allow you to run Java programs.

A great option is to download the Java SE Development Kit (JDK) 7 Update 7 (7u7) from Oracle's Java SE Downloads page. What you'll need to get started is a Java compiler and Java virtual machine, both of which must support Java 7. (Use the "Add/Remove Programs" utility in the Windows Control Panel to uninstall Java delete the "eclipse" folder to delete Eclipse.) Leaving old versions causes setup of Java 7 to be more complicated and problematic, and an old version of Eclipse will not recognize the new version of Java without some rather messy settings changes, whereas installing Eclipse after installing the new Java will cause Eclipse to find and use Java 7. Removing Eclipse and previous versions of Javaįirst, it's best if you delete Eclipse and uninstall all earlier versions of Java you have installed on your machine. It is a bit tricky to install properly read the directions of the site carefully. The version you want is at this link in particular:

If you want to run Java 7 under a version of Mac OS X prior to 10.7 (Lion), there is a version from the OpenJDK group available at. Installing on Mac OS X versions older than 10.7 (Lion) If you use Linux or Solaris, JDK 7 Update 7 (7u7) can be downloaded from Oracle's Java SE Downloads page, the same way it can for Windows, and can also be downloaded using built-in "package managers." Installation procedures vary from one distribution of Linux to another, but ample documentation is available online. To install Java 7 and Eclipse on either of these operating systems, see the applicable section below.

Installing on Windows or Mac OS X 10.7 (Lion)īefore you get started, be aware that this document only describes how to set up Java 7 and Eclipse on a computer running Windows or Mac OS X 10.7 (Lion).
