java如何编写用鼠标脱出轨迹 我的代码怎么修改就有轨迹了 求帮助

把鼠标的x和y放一个队列里，限定队列长度，每次都把队列里的点画出来就行了。

用java写一个物体移动的轨迹

lz 你好

我做了一个比较简单的雏形

绿色正方形水平随机运动

蓝色正方形垂直随机运动

import java.awt.*;

import javax.swing.*;

import java.awt.event.*;

import java.math.*;

public class MoveRect extends Frame implements Runnable{

    private Rectangle hRect, vRect;

    private Image buffer;

    private Object o = new Object();

    public MoveRect(){

        super("MoveRect");

        hRect = new Rectangle(50,0,50,50);//水平随机运动的正方形

        vRect = new Rectangle(0,50,50,50);//垂直随机运动的正方形

        setUndecorated(true);  

        setLocation(500,200);

        setSize(400,400);

        setVisible(true);

        addWindowListener(new WindowAdapter(){

            public void windowClosing(WindowEvent e){

                System.exit(0);

            }

        });

    }

    //启动循环绘制(使正方形一直循环的运动)

    public void circleDraw(){

    }

    //绘制正方形的状态

    public void drawRect(Graphics g,Rectangle r){

        g.drawRect(r.x, r.y, r.width, r.height);

    }

    //双缓冲机制(主要解决闪屏)

    public void update(Graphics g){

        buffer = createImage(getSize().width, getSize().height);

        if(buffer != null){          

            Graphics g2 = buffer.getGraphics();

            paint(g2);

            g2.dispose();      

            g.drawImage(buffer, 0, 0, this);        

        }

        else{

            paint(g);

        }

    }

    public void paint(Graphics g){      

        g.setColor(Color.GREEN);

        drawRect(g,hRect);

        g.setColor(Color.BLUE);

        drawRect(g,vRect);

        hRect.x = (int)(Math.random()*351);

        vRect.y = (int)(Math.random()*351);  

    }

    public void run(){

        while(true){

            stop();

            rePaint();

        }              

    }

    //同步方法rePaint

    public synchronized void rePaint(){

        repaint();

    }

    //同步方法stop

    public synchronized void stop(){

        if(hRect.x = 50  vRect.y = 50){

            try {

                Thread.sleep(500);

            }

            catch (Exception ex) {

                ex.printStackTrace();

            }

        }      

    }

    public static void main(String[] args){    

        new Thread(new MoveRect()).start();

    }

}

Java怎么作一个记录鼠标坐标的程序？？

import java.awt.*;

import java.awt.event.*;

public class Test {

public static void main(String args[]) {

new myFrame();

}

}

class myFrame extends Frame {

TextField tf1,tf2;

public myFrame(){

tf1 = new TextField(5);

tf2 = new TextField(5);

add(tf1);

add(tf2);

setLayout(new FlowLayout());

setBounds(100,100,400,300);

addMouseMotionListener(new MouseMotionAdapter(){//鼠标移动事件的侦听器

public void mouseMoved(MouseEvent e) {//鼠标按键在组件上移动（无按键按下）时调用。

tf1.setText(e.getX()+"" );

tf2.setText(e.getY()+"" );

}

});

addWindowListener(new WindowAdapter(){

public void windowClosing(WindowEvent e) {

System.exit(0);

}

});

setVisible(true);

}

}

用JAVA实现画线，不是直线，而是点住鼠标左键划到哪里哪里就画线，就

请教一个java中点击鼠标绘制图形的问题

人家都是在此点与上点之间绘直线。否则就是这样。此法记得是在《windows程序设计》一书里讲的。
