非常好的几个案例,19个小游戏源码。。。 希望大家喜欢

import javax.microedition.lcdui.*;

public class OCanvas extends Canvas {
  private Display display;

  public OCanvas(Display d) {
    super();
    display = d;
  }

  void start() {
    display.setCurrent(this);
    repaint();
  }

  public void paint(Graphics g) {
    // Clear the display
    g.setColor(255, 255, 255);  // White
    g.fillRect(0, 0, getWidth(), getHeight());

    // Draw the first row of circles
    g.setColor(0, 0, 255);    // Blue
    g.drawArc(5, 5, 25, 25, 0, 360);
    g.setColor(0, 0, 0);      // Black
    g.drawArc(35, 5, 25, 25, 0, 360);
    g.setColor(255, 0, 0);    // Red
    g.drawArc(65, 5, 25, 25, 0, 360);

    // Draw the second row of circles
    g.setColor(255, 255, 0);  // Yellow
    g.drawArc(20, 20, 25, 25, 0, 360);
    g.setColor(0, 255, 0);    // Green
    g.drawArc(50, 20, 25, 25, 0, 360);
  }
