when i run the program it is showing an error message "Class progressbar.Prgressbar does not have a main method"...... what does it mean ??
plz help..

[zeroliken]

you need to put the main method and all your methods inside your public class

private Container getContentPane() {
throw new UnsupportedOperationException("Not yet implemented");
}
}

the last bracket here ends your public class
and don't put ); after the end brackets

*next time wrap your code in code tags so we can just point out what line you got the error
