It has got a default method which is paint() method. Canvas class can be sub classed to override this default method to define your own components as shown below in the example.

import java.awt.*;

import java.applet.*;

 

public class MyCanvas extends Applet { 

  public MyCanvas() { 

      setSize(80, 40); 

  } 

  public void paint(Graphics g) { 

  g.drawRect(0, 0, 90, 50);  

    g.drawString("A Canvas", 15,15); 

  } 

}

Here is the Output:
