text: The simplest component is
  java.awt.Label. A
  Label is one line of read-only text, pretty much perfect for
  a Hello World applet.
  import java.applet.*; import java.awt.*; public class HelloContainer extends Applet { public void init() { Label label; label = new Label("Hello Container"); this.add(label); } }
  As usual you begin by importing the classes you need. In this
  case you need only two,
  java.applet.Applet and
  java.awt.Label and lines 1 and 2 import them.
  Line 4 declares the class in the usual way as an extension of
  Applet. The class has a single method,
  init().
  Line 6 starts the
  init() method. The
  init() method does three things. First line 7 declares that
  l is a
  Label. Then
  l is
  instantiated with the
  Label(String s) constructor in
  Line 8. Finally
  l is added to the layout in line 9.
  Components don't have to be added to the layout in the
  init() method nor do they need to be instantiated there, but
  it's often convenient to do so.
