title: running java program from command line with classpath
body: <p>Most of the time when i am learning something i am running java program from commandline.</p>
  
  <p>now my problem is little complecated.</p>
  
  <p>i am running Simple java program from command line. But i need CLASSPATH variable in environment variables. when i am adding CLASSPATH variable my program is giving me error.
  The error is classNOtFoundException. Means when i am running program it will check .class file and it is going in my classpath variable and that is obvious it will not found and it will fire exception. 
  i am always working line this. this problem occurs after i have formatted my PC. but i am using same OS and same jdk as it was.</p>
  
  <p>Any body have faced this type of issue?
