first of all you need to set class path in environment variables
1.goto my computer-> system properties -> advanced system settings -> environment variables.
2. in the environment variables menu in the first box you need to set the path of the java i.e., jdk path
ex:- .;C:\Program Files (x86)\Java\jdk1.6.0\bin;
and then okk..
3. now you can compile and execute the java program as mentioned by nareshkumar..
