How to Set Path in Java

The path is a variable required for the System to give an execution environment to the java application. With java development kit we get the required environment for execution and compilation environment. When we run a java command we have to specify the location where command definition can be found. We do that by setting the classpath.

There are two way to set the classpath

1. Temporarily path
2. Permanently path
