最近在做一个数据结构的课程设计遇上些麻烦,其中有个问题想了好几天还是没头绪的,于是只能上网求助各位了。。。由于明儿要第一次演示程序的,而我又刚好在最后的一个坎给卡主了,所以希望大家能帮助我,我在线等的。。。下面是我为了说明问题写的一个简易的小程序例子:
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.*;
public class test03 extends JFrame implements ActionListener{
/**
* @param args
*/
JPanel p1;
JLabel jlb;
JButton jb1;
public static void main(String[] args) {
// TODO Auto-generated method stub
test03 test03 = new test03 ();
}
public test03(){
p1=new JPanel();
p1.setBackground(Color.black);
//p1.setLayout(new BorderLayout());
jb1=new JButton("新建一个窗口");
jb1.addActionListener(this);
p1.add(jb1);
this.add(p1);
this.setSize(615, 473);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
}
@Override
public void actionPerformed(ActionEvent arg0) {
// TODO Auto-generated method stub
test04 test04 = new test04 ();
}
}
class test04 extends JFrame implements ActionListener{
JPanel p11;
JLabel jlb1;
JButton jb11;
Boolean []bool=new Boolean[11];
int cc=0;
int count=0;
public test04(){
for(int i=0;i<11;i++){
bool[i]=true;
}
p11=new JPanel();
p11.setBackground(Color.black);
jb11=new JButton("画图");
jb11.addActionListener(this);
p11.add(jb11);
this.add(p11);
this.setSize(615, 473);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
}
public void paint(Graphics g) {
super.paint(g);
g.setColor(Color.green);
while( bool[cc] ){
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
cc++;
g.fillOval(10, 10, 10, 10);
while( bool[cc] ){
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
cc++;
g.fillOval(91, 105, 10, 10);
while( bool[cc] ){
