title: java runs in eclipse but won't run in command prompt
body: <p>Just today I noticed that I can run java in eclipse with no problems but when I try to run it in the command prompt, I get "cannot find or load main class." The command prompt actually compiles all right, and it outputs a .class file, but then it displays the error msg when trying to execute. (Also, I was able to run java in the cmd a couple weeks ago.)</p>

  public static void main (String [] args) {
      System.out.println("welcome to java!");
  
  
  
  }
  
  }
