java GUI模拟平抛运动和自由落体运动

简单做了一个

public class MyFrame extends Frame implements Runnable,ActionListener{

double x1 = 100,y1 = 0;//A的起始位置

double x2 = 100,y2 = 0;//B的起始位置

double s2 = 26;//B的水平速度

double g = 9.8;//G

long time = 10000;//模拟10秒钟

double py = 1;//y轴比例尺

ListPoint list1 = new ArrayListPoint();

ListPoint list2 = new ArrayListPoint();

MPanel p1 = new MPanel();

Button b1 = new Button("启动");

Thread t ;

public MyFrame(){

b1.addActionListener(this);

this.add(b1,BorderLayout.NORTH);

}

list1.add(new Point(sx1,sy1));

list2.add(new Point(sx2,sy2));

p1.repaint();

try {

Thread.sleep(50);

} catch (InterruptedException e) {

}

}

}

public void actionPerformed(ActionEvent e) {

}

}

Point ppp1 = null;

Point ppp2 = null;

for (int i=0;ilist1.size();i++){

Point pp1 = list1.get(i);

Point pp2 = list2.get(i);

if (ppp1!=nullppp2!=null){

g.drawLine(pp1.x,pp1.y,ppp1.x,ppp1.y);

}

g.dispose();

gg.drawImage(im,0,0,800,600,p1);

}

}

public static void main(String[] args) {

new MyFrame();

}

}

java控制红绿灯及模拟车辆运动

写两个程序分别模拟红绿灯和汽车：

1）红绿灯程序以报文形式通知汽车程序；

2）汽车程序需要用多线程来实现。

3）红绿灯程序用个循环，每隔n分钟红绿灯转换，同时通知汽车程序；

JAVA 模拟小球自由落体和平抛运动

这个绝对可以的，我都试过了。请采纳，谢谢。

import java.awt.*;

import java.awt.event.*;

import java.applet.*;

public class BallThread extends Applet implements Runnable{

Thread red, blue;

Graphics redPen, bluePen;

int t=0;

public void init(){

red = new Thread(this);

blue = new Thread(this);

redPen = getGraphics();

bluePen = getGraphics();

redPen.setColor(Color.red);

bluePen.setColor(Color.blue);

}

public void start(){

red.start();

blue.start();

}

public void run(){

while(true){

t=t+1;

if(Thread.currentThread()==red){

if(t100)t=0;

redPen.clearRect(0,0,110,400);

redPen.fillOval(50,(int)(1.0/2*t*9.8),15,15);

try{

red.sleep(40);

}catch(InterruptedException e){}

}else if(Thread.currentThread()==blue){

bluePen.clearRect(120,0,900,500);

bluePen.fillOval(120+7*t,(int)(1.0/2*t*9.8),15,15);

try{

blue.sleep(40);

}catch(InterruptedException e){}

}

}

}

}
