這裏涉及了，生產者文件，消費者文件，貨物架文件，界面設計文件，還有就是一個applet文件．
Consumer文件：
import java.util.*;
public class Consumer extends Thread
{
private WorkQueue queue;
public Consumer(WorkQueue queue)
{
this.queue=queue;
}
public void run()
{
for(;;)
{
try{
queue.removeWork();
sleep(1500);
}
catch(InterruptedException e)
{
e.printStackTrace();
}
}
}
}
Producer文件
import java.util.*;
public class Producer extends Thread
{
private WorkQueue queue;
public Producer(WorkQueue queue)
{
this.queue=queue;
}
public void run()
{
int product=0;
while(true)
{
try{
queue.addWork(String.valueOf(++product));
sleep(1000);
}
catch(InterruptedException e)
{
e.printStackTrace();
}
}
}
}
WorkQueue文件：（貨物架）
import java.util.*;
import javax.swing.*;
import java.awt.*;
public class WorkQueue
{
final int NUMBER=10;
static String temp="開始了";
static String t="消費了";
int i=0;
MyApplet text;
LinkedList list=new LinkedList();
public WorkQueue()
{
}
public WorkQueue(MyApplet text)
{
this.text=text;
}
public synchronized void addWork(String product)throws InterruptedException
{
if(list.size()==NUMBER)
{
text.productText.setText("貨物架已滿");
try{
wait();
}
catch(InterruptedException e)
{
e.printStackTrace();
}
}
list.addLast(product);
temp=" ,"+(String)list.get(i++)+temp;
text.productText.setText(temp);
if(list.isEmpty())
{
}
notifyAll();
}
public synchronized void removeWork() throws InterruptedException
{
while(list.isEmpty())
{
text.consumText.setText("沒有產品供消費者享用了");
try{
wait();
}
catch(InterruptedException e)
{
e.printStackTrace();
}
}
t=" ,"+(String)list.removeFirst()+t;
text.consumText.setText(t);
}
}
MyApplet文件(界面設計)
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MyApplet extends JApplet implements ActionListener
{
WorkQueue queue=new WorkQueue();
JButton productButton;
JButton consumButton;
static JTextField productText;
static JTextField consumText;
static JTextField stateText;
public void init()
{
Container con=getContentPane();
con.setLayout(new FlowLayout());
productText=new JTextField(20);
consumText=new JTextField(20);
stateText=new JTextField(20);
productButton=new JButton("Start Product");
consumButton=new JButton("Start Consum");
con.add(productButton);
con.add(productText);
con.add(consumButton);
con.add(consumText);
con.add(stateText);
productButton.addActionListener(this);
consumButton.addActionListener(this);
}
public void actionPerformed(ActionEvent e)
{
if(e.getSource()==productButton)
{
Thread productT=new Producer(queue);
productT.start();
stateText.setText("生產者正在生產產品");
}
if(e.getSource()==consumButton)
{
new Consumer(queue).start();
stateText.setText("消費者正在消費產品");
}
}
}
JAVA Applet文件：
<html>
<applet code="MyApplet.class" height="200" width="400"></applet>
</html>
其運行效果如下：
