  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..
