第二篇 多线程（二）

package com.zzp.thread;
/**
 * 
 * 静态代理
 * @author java
 *
 */
public class StaticProxy {
    public static void main(String[] args) {
        new WedCompany(new You()).happyWedding();
    }
}

interface Wedding{
    void happyWedding();
}

class You implements Wedding{
    @Override
    public void happyWedding() {
        System.out.println("终于结婚了");
    }
}

class WedCompany implements Wedding{
    private Wedding target;
    
    public WedCompany(Wedding target) {
        super();
        this.target = target;
    }

    @Override
    public void happyWedding() {
        before();
        this.target.happyWedding();
        after();
    }
    
    public void before(){
        System.out.println("布置狗窝！！！");
    }
    
    public void after(){
        System.out.println("闹玉兔！！！");
    }
}

 Lamdba(jdk1.8)新特性

package com.zzp.thread;

public class LambdaTest {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ILove il = (int a)-> {
            System.out.println("I like the world"+a);
        }
        il.lambda(100);
        //类型可以省略
        il = (a)-> {
            System.out.println("I like the world"+a);
        }
        il.lambda(500);
        //只有一个参数的情况下，括号也可以省略
        il = a-> {
            System.out.println("I like the world"+a);
        }
        il.lambda(30);
        
        //如果只有一行代码，花括号也可以省略
        il = a-> System.out.println("I like the world"+a);
        il.lambda(11);
    }

}

interface ILove{
    void love(int a);
}

class ILike implements ILove{

    @Override
    public void love(int a) {
        System.out.println("I like the world"+a);
    }
    
}

带参数返回值的lambda表达式

package com.zzp.thread;
/**
 * 
 * lambda带参数的返回值
 * @author java
 *
 */
public class LambdaTest02 {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ILove il = (int a,int c)-> {
            System.out.println("是吗？");
            return a+c;
        }
        il.lambda(100,200);
        //类型可以省略
        il = (a,c)-> {
            System.out.println("是吗？");
            return a+c;
        }
        il.lambda(500,1000);
        
        il = (a,c)-> {
            return a+c;
        }
        il.lambda(30,100);
        
        //如果只有一行代码，花括号也可以省略
        il = (a,c)-> a+c;
        il.lambda(11,12);
    }

}

interface ILove{
    int love(int a,int b);
}

class ILike implements ILove{

    @Override
    public int love(int a,int c) {
        System.out.println("是吗？");
        return a+c;
    }
    
}

 多线程使用lambda表达式

package com.zzp.thread;
/**
 * 
 * lambda带参数的返回值
 * @author java
 *
 */
public class LambdaTest03 {

    public static void main(String[] args) {
        new Thread(()->{
            for(int i=0;i<10;i++){
                System.out.println("一边学习");
            }
        }).start();
        
        new Thread(()-> System.out.println("一边学习");).start();
    }
        
}
