Question

I am really fresh at Java.

I’have created new Java Project. Created package Main and Main.java class Main in this package.

package Main;

public class Main {
     public Main(String[] argv) {
          System.out.println("Helloworld.");
     }
}

When I try to run it – Eclipse gives an error: Selection does not contain applet.

Answer 1

Don’t create/run-as applet.

Some other notes:

1) main methods must be declared as follows in order to be recognized as an entry point:

public static void main(String[] argv) {
    // Your code here
}

The name of the parameter is arbitrary, but usually argv or args.

2) Packages should be named in all-lower case. Method names should start with a lower-case letter.
