Applets don't have a main method in Java. Then how can your program get the output.

Did you extend the Applet class?
Quote:
public class HelloWorld extends Applet

here is a program sample
import java.awt.Graphics;
public class HelloWorld extends java.applet.Applet {
public void init() {
resize(150,25);
}
public void paint(Graphics g) {
g.drawString("Hello world!", 50, 25);
}
}

Code:
import java.awt.Graphics;


/*<applet code="HelloWorld"></applet>*/


public class HelloWorld extends java.applet.Applet {

    public void init() 
    {
    resize(150,25);
    }
    public void paint(Graphics g) 
    {
    g.drawString("Hello world!", 50, 25);
    }
}
The code is correct. But when you run from terminal, it will not run till you add the bold lines.

Applets are loaded in a browser. So, either you can create a HTML file named HelloWorld and add the <applet> tag to it.
Or you can add the tag in the Java file itself as above.
And run the program.
Code:
$javac Helloworld.java
$appletviewer Helloworld.java
