The canvas code

Translating the steps above to Java code gives us this…

HelloWorldCanvas.java

importjavax.microedition.lcdui.Canvas;

importjavax.microedition.lcdui.Graphics;

public class HelloWorldCanvas extends Canvas {

        protected void paint(Graphics g) {

               g.setColor(0, 0, 0);

               g.fillRect(0, 0, getWidth(), getHeight());

               g.setColor(255, 255, 255);

               g.drawString("Hello World!", 20, 20, Graphics.LEFT | Graphics.BOTTOM);

        }

}
