Its’s built-in platform-independent windowing, graphics, and user-interface widget toolkit. The java.awt is now part of the Java Foundation Classes (JFC). Which can be used for a graphical user interface (GUI) for a Java program. AWT consists of many classes which can be said: Components. A component is a class which can create a event specific GUI like TextField, Button, Label, Checkbox, TextArea, etc…

To add any component in Applet area, We have to call a add(Component c) method of Applet class. Which is discussed briefly in the below example.

import java.applet.*;
import java.awt.*;

public class componentDemo extends Applet
{
	Button b;
	Label l;
	TextField tf;
	Scrollbar sb;
	TextArea ta;
	Checkbox c1,c2,c3;
	CheckboxGroup cbg = new CheckboxGroup();
	public void init()
	{
		tf = new TextField("Ankit",20);
		l = new Label("First Name:");
		b = new Button("Okay!");
		ta = new TextArea(7,40);
		sb = new Scrollbar(Scrollbar.VERTICAL, 100, 20, 0, 200);
		sb.setPreferredSize(new Dimension(30,200));
		c1 = new Checkbox("Cricket",true,cbg);
		c2 = new Checkbox("Hockey",false,cbg);
		c3 = new Checkbox("Football",false,cbg);
		add(l);
		add(tf);
		add(b);
		add(sb);
		add(ta);
		add(c1);
		add(c2);
		add(c3);
	}	
}
