这个小程序，我用两个Class来编写。是为了使得代码更加清楚，增强其可读性。

AutoFrame这个类里只是一个窗口类，用来实现以基本窗口的显示。

AutoFrame Code:

import javax.swing.JFrame;

public class AutoFrame extends JFrame{

    /* Define the global variable */
    int WIDTH = 500, HEIGHT = 400; // define the initial size
    int X = 0, Y = 0; // define the initial location
    
    /* The constructor */
    public AutoFrame() {
        // TODO Auto-generated constructor stub
    }
    
    /* Display the window function */
    public void showFrame()
    {
        this.setSize(WIDTH, HEIGHT);
        this.setLocation(X, Y);
        this.setTitle("MY AUTO WINDOW");
        
        this.setVisible(true); // set the window is visible
        this.setDefaultCloseOperation(EXIT_ON_CLOSE); // set the window can close with close button
    }
}

 

WindowAction这个类里则是真正的窗口动作类。

WindowAction类里调用了thread线程现实窗口的自动移动和自动改变大小动作。

WindowAction Code:

public class WindowAction extends Thread {

    static AutoFrame af = new AutoFrame(); // Create a object of AutoFrame
    private int TIMES = 100; // define a limit times for the cycle

    public void run() {
        int times = TIMES; // define the cycle times is TIMES

        int x = af.X, y = af.Y, w = af.WIDTH, h = af.HEIGHT; // Save the old values
        int i;
        for (i = 0; i <= times; ++i) { // cycle to change location of the window
            af.showFrame();
            af.setLocation(++af.X, ++af.Y); // reset location of the window
            System.out.println("times = " + i + ":");
            try {
                sleep(100);
                System.out.println("The frist thread sleep one second...\n");
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        
        for (i = 0; i <= times; ++i) { // cycle to change location of the window
            af.showFrame();
            af.setSize(--af.WIDTH, --af.HEIGHT); // reset size of the window
            System.out.println("times = " + i + ":");
            try {
                sleep(100); // sleep 0.1 second
                System.out.println("The second thread sleep one second...\n");
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }

    public static void main(String[] args) {
        new WindowAction().start(); // call the function who in thread to start the thread
    }
}
