Applet is different from a typical Java application where it has to work with the Java environment itself. On the other hand, applet must work within another application like an HTML page. Thus, it requires a browser.
The class name must be the compiled Java program. They are to be of the same location to work. Do check the needed Java program below.
import java.applet.*;
import javax.swing.*;
public class AppletGreet1 extends Applet {
JLabel greeting = new JLabel("Hello world");
@Override
public void init()
{
add(greeting);
}
}
