3.Set Path
•
After installing the software, the JDK directory will have the structure shown below.
•
The bin directory contains both the compiler and the launcher. The path environmental variable should be
updated to include path to bin in PATH variable. This is not mandatory, but highly recommended for convenience.
•
It is useful to set the PATH variable permanently so it will persist after rebooting.
•
To set the PATH variable permanently, add the full path of the jdk1.7.0\bin directory to the PATH variable. Typically,
this full path looks something like C:\Program Files\Java\jdk1.7.0\bin in Windows o/s.
•
Refer: http://docs.oracle.com/javase/tutorial/essential/environment/paths.html to learn how to do this.
•
For example, in Windows 7:
