今天我們鞏固一下前幾節所學到的線程
我們希望寫一個程序，可以不斷的輸入，不斷的輸出
首先我們用以前的方式編寫
接下來我們來看一段代碼

/*** 不斷進行輸入一個人的姓名和性別操作，同時進行輸出* @author lover**/ class resourse{int x=1;private String name;private String sex;boolean flag=false;public void chushi(String name,String sex){this.name=name;this.sex=sex;}public synchronized void input(){ if(flag){try {wait();} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}}else{if(x==1){this.chushi("王海學", "男");}else{this.chushi("邵玥", "小仙女");}x++;x=x%2;flag=true;notifyAll();}}public synchronized void output(){if(!flag){try {wait();} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}}else{System.out.println(Thread.currentThread().getName()+"..........."+this.name+"----"+this.sex);flag=false;notifyAll();}} } class put implements Runnable{resourse r;public put(resourse r){this.r=r;}public void run(){while(true){r.input();}} } class out implements Runnable{resourse r;public out(resourse r){ this.r=r;}public void run(){while(true){r.output();}} } public class Text { public static void main(String[] args) {resourse r=new resourse();put p=new put(r);out o=new out(r);Thread pp=new Thread(p);Thread oo=new Thread(o);pp.start();oo.start(); } }

我們來看看輸出

Thread-1...........邵玥----小仙女 Thread-1...........王海學----男 Thread-1...........邵玥----小仙女 Thread-1...........王海學----男 Thread-1...........邵玥----小仙女 Thread-1...........王海學----男 Thread-1...........邵玥----小仙女 Thread-1...........王海學----男 Thread-1...........邵玥----小仙女 Thread-1...........王海學----男 Thread-1...........邵玥----小仙女

接下來我們將改寫成jdk1.5之后的代碼即使用鎖
代碼如下

import java.util.concurrent.locks.Condition; import java.util.concurrent.locks.Lock; import java.util.concurrent.locks.ReentrantLock;/*** 不斷進行輸入一個人的姓名和性別操作，同時進行輸出* @author lover**/ class resourse{int x=1;private String name;private String sex;boolean flag=false;private Lock lock=new ReentrantLock();private Condition con=lock.newCondition();public void input(){lock.lock();try{while(flag){try {con.await();} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}}if(x==1){this.chushi("王海學", "男");}else{this.chushi("邵玥", "小仙女");}x++;x=x%2;flag=true;con.signal();}finally{lock.unlock();}}public void output(){lock.lock();try{while(!flag){try {con.await();} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}}System.out.println(Thread.currentThread().getName()+"..........."+this.name+"----"+this.sex);flag=false;con.signal();}finally{lock.unlock();}}public void chushi(String name,String sex){this.name=name;this.sex=sex;} } class put implements Runnable{resourse r;public put(resourse r){this.r=r;}public void run(){while(true){r.input();}} } class out implements Runnable{resourse r;public out(resourse r){ this.r=r;}public void run(){while(true){r.output();}} } public class Text { public static void main(String[] args) {resourse r=new resourse();put p=new put(r);out o=new out(r);Thread pp=new Thread(p);Thread oo=new Thread(o);pp.start();oo.start(); } }

輸出如下

Thread-1...........邵玥----小仙女 Thread-1...........王海學----男 Thread-1...........邵玥----小仙女 Thread-1...........王海學----男 Thread-1...........邵玥----小仙女 Thread-1...........王海學----男 Thread-1...........邵玥----小仙女 Thread-1...........王海學----男 Thread-1...........邵玥----小仙女 Thread-1...........王海學----男 Thread-1...........邵玥----小仙女 Thread-1...........王海學----男
