JAVA设计使用管道流的发牌程序-报告JAVA2程序设计实用教程之Java的面向对象特征上机报告|上机实验实习报告|计算机上机实习报告|JAVA设计使用管道流的发牌程序在例7.9中我们利用线程调度设计了一个发牌程序，请结合本例，设计使用管道流的发牌程序。import java.awt.*;import java.awt.event.*;import java.io.*;public class Card extends WindowAdapter Frame f; TextArea ta1,ta2,ta3,ta4; public void display() f = new Frame(Send Card); f.setSize(400,300); f.setLocation(200,140); f.setBackground(Color.lightGray); f.setLayout(new GridLayout(2,2); f.addWindowListener(this); ta1 = new TextArea(,5,10,3); /文本区没有滚动条 ta2 = new TextArea(,5,10,3); ta3 = new TextArea(,5,10,3); ta4 = new TextArea(,5,10,3); Font font1 = new Font(Helvetica, Font.PLAIN, 20); ta1.setFont(font1);ta2.setFont(font1); ta3.setFont(font1);ta4.setFont(font1); f.add(ta1);f.add(ta2);f.add(ta4); f.add(ta3);f.setVisible(true); public void windowClosing(WindowEvent e) System.exit(0); public static void main(String arg) Card p = new Card(); p.display(); PipedInputStream in=new PipedInputStream(); PipedOutputStream out=new PipedOutputStream(); try in.connect(out); catch(IOException ioe) Sender3 s = new Sender3(out,52); s.start(); /启动发牌线程 s.setPriority(1); /设置最高优先级,值为1 Receiver3 r1=new Receiver3(in,p.ta1); /创建四个取牌线程 Receiver3 r2=new Receiver3(in,p.ta2); Receiver3 r3=new Receiver3(in,p.ta3); Receiver3 r4=new Receiver3(in,p.ta4); r1.start(); r2.start(); r3.start(); r4.start(); class Sender3 extends Thread /发牌线程 PipedOutputStream out; int count; public Sender3(PipedOutputStream out,int c) this.out=out; this.count = c; public void run( ) try for (int i=1;i=count;i+) out.write(i); catch(IOException e) class Receiver3 extends Thread /取牌线程 PipedInputStream in; TextArea ta; public Receiver3(PipedInputStream in,TextArea ta) this.in=in; this.ta = ta ; synchronized public void run() while(true) try int i=in.read(); if(i!=-1) ta.append( +i); wait(1000); catch(IOException e) catch(InterruptedE
