exception in thred main java.lang.nosuchmethoderror: main

[fernando]

Hi, I have the following code:

import java.awt.*;
import java.applet.*;
public class Button1 extends Applet {
Button
b1 = new Button("Button 1"),
b2 = new Button("Button 2");
public void init() {
add(b1);
add(b2);
}
}

When i compile it, everything going alright, but when i execute it the following error appear:
exception in thread main java.lang.nosuchmethoderror: main
why?
Thanks.

At the prompt you run an application with >java MyClass.java
For an applet you use the appletviewer: >appletviewer MyApplet.java
and for this to work your java/source file must have an applet tag in it, like so

//  <applet code="Button1" width="200" height="200"></applet>
java.awt.*;
import java.applet.*;

public class Button1 extends Applet {
    Button
        b1 = new Button("Button 1"),
        b2 = new Button("Button 2");

    public void init() {
        add(b1);
        add(b2);
    }
}
