多线程，奇数偶数，生产者，消费者 java

一、奇数偶数
1.Date

public class Date { private int num; public int getNum() { return num; } public void setNum(int num) { this.num = num; } public Date(int num) { super(); this.num = num; } public synchronized void Even() { this.notifyAll(); if(num%2==0) { System.out.println("Even"+Thread.currentThread().getName()+"-->"+(num++)); try { Thread.sleep(1000); this.wait(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } public synchronized void Odd() { this.notifyAll(); if(num%2!=0) { System.out.println("Odd"+Thread.currentThread().getName()+"-->"+(num++)); try { Thread.sleep(1000); this.wait(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } }

2.AThread

public class AThread implements Runnable { private Date date; public AThread(Date date) { super(); this.date = date; } @Override public void run() { while(true) { date.Even(); } } }

3.BThread

public class BThread implements Runnable { private Date date; public BThread(Date date) { super(); this.date = date; } @Override public void run() { while(true) { date.Odd(); } }}

4.Test

public class Test { public static void main(String[] args) { Date date=new Date(0); AThread a=new AThread(date); BThread b=new BThread(date); Thread t1=new Thread(a); Thread t2=new Thread(b); t1.start(); t2.start(); } }

二、生产者，消费者
1.Food

package com.pro.food; public class Food { private String name; private String type; private int j; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getType() { return type; } public void setType(String type) { this.type = type; } public int getJ() { return j; } public void setJ(int j) { this.j = j; } public Food(int j) { super(); this.j = j; } }

2.Product

package com.pro.food; public class Product implements Runnable { private Food food; private int i=0; public Product(Food food) { super(); this.food = food; } @Override public void run() { while(true) { synchronized(food) { food.notifyAll(); if(food.getJ()==0) { if(i%2==0) { food.setType("炒饭"); food.setName("蛋炒饭"); food.setJ(1); }else if(i%2!=0) { food.setType("包子"); food.setName("肉包"); food.setJ(1); } i++; System.out.println("生产了"+food.getType()+"-"+food.getName()); }else if(food.getJ()==1) { try { Thread.sleep(1000); food.wait(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } } }}

3.Consumer

package com.pro.food; public class Consumer implements Runnable { private Food food; public Consumer(Food food) { super(); this.food = food; } @Override public void run() { while(true) { synchronized (food) { food.notifyAll(); if(food.getJ()==1) { System.out.println("拿到了"+food.getType()+"-"+food.getName()); food.setJ(0); }else if(food.getJ()==0) { try { Thread.sleep(1000); food.wait(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } } }}

【多线程，奇数偶数，生产者，消费者】4.Test

package com.pro.food; public class Test { public static void main(String[] args) { Food food=new Food(0); Product pro=new Product(food); Consumer con=new Consumer(food); Thread t1=new Thread(pro); Thread t2=new Thread(con); t1.start(); t2.start(); } }
