Issue in run java applet program

Question

I'm new to java: When i'm studying package, there are lots of packages available in java platform.

This is my code:

package day1.examples;
import java.applet.*;
import java.awt.*;
public class HelloWorld extends Applet {
    public void paint(Graphics g) {
        g.drawString("Hello world!", 50, 25);
    }
}

When i run this code, it shows this warning :"The import java.applet is never used"

My page look like this:

enter image description here

Can anyone help me?

it is not error. it is just warning. the code should work fine — Adem, Dec 13 '14 at 11:53
@adem: how to view the output.. i mean,, how to add println? or how to fix the warning/ — , Dec 13 '14 at 11:54
eclipse should detect your class is an applet. but, if not, select "run configurations" and then select "Java Applet" on new window. but, I am almost sure eclipse should be able to detect it is an applet. are you sure you are doing this when your applet code is open ? — Adem, Dec 13 '14 at 11:58
are you trying to extend `java.applet.Applet` or your `Applet` class in your package. — Johny, Dec 13 '14 at 12:01
@johny you are right. sss has another class that named Applet. try to extend java.applet.Applet , or remove your Applet class — Adem, Dec 13 '14 at 12:03

You are extending the Applet class in your package. To use the java.applet.Applet you have to either remove Applet from your package or do the following

import java.awt.*;
public class HelloWorld extends java.applet.Applet {
   public void paint(Graphics g) {
      g.drawString("Hello world!", 50, 25);
   }
}

`g.drawString("Hello world!", 50, 25)` prints `Hello world!` at the coordinate (50,25). – Johny Dec 13 '14 at 12:20
sorry, what is that name(technically), in this program, and what is Graphis g? Thanks. – Dec 13 '14 at 12:27
Graphics is a class which has different methods used for displaying image, text, etc.. inside your applet. – Johny Dec 13 '14 at 12:32
