Go to my computer and right click to select properties. Then go to advanced system settings and select advanced tab. Now click on environment variables. Now in the system variables box search for the 'PATH' tag and double click on it. Now set the Jre and jdk the paths followed by a semicolon after each complete path in the valriable values box. Now click on ok. Now again in the system variables box create a new tag name 'CLASSPATH' by clicking on the new button. After you have created a classpath tag then double click on it. Now in the variables value set the jre and jdk paths. And at the end of the second path put a full-stop ' . ' after the semi colon. Now click ok in all the windows that you have opened.
