java例程练习(Graphics类[paint()方法])
//Graphics类---简单的画图实现
import java.awt.*;
public class TestPaint {
public static void main(String[] args) {
new PaintFrame().launchFrame();
}
}
class PaintFrame extends Frame {
public void launchFrame() {
setBounds(200, 200, 700, 500);
setVisible(true);
}
public void paint(Graphics g) {//每次需要重画时自动调用paint()方法
Color c = g.getColor();
g.setColor(Color.red);
g.fillOval(50, 50, 50, 50);
g.setColor(Color.green);
g.fillRect(100, 100, 80, 80);
g.setColor(c);
}
}
