exception in thread 'main' java.lang.NoClassDefFoundError:

Question

The following program is throwing error:

public class HelloWorld {
    public static void main(String args[]) {
        System.out.println(\"Hello World!\");         


        

Answer 1

Your CLASSPATH needs to know of the location of your HelloWorld class also.

In simple terms you should append dot . (means current directory) in the CLASSPATH if you are running javac and java commands from DOS prompt.
