jdk8-lambda表达式

Java 中 Lambda 表达式一共有五种基本形式，具体如下：

public static void main(String[] args) {

    example4();

}

 

public static void examlpe1(){

Runnable r1 = ()-> System.out.println("hello world");

Thread t = new Thread(r1);

t.start();

}

 

public static void examlpe2(){

Function f = (name)-> System.out.println(name+"hello world");

f.getName("a");

}

 

public static void examlpe13(){

Runnable r1 = ()->{

System.out.println("hello world");

System.out.println("hello world2");

};

Thread t = new Thread(r1);

t.start();

}

 

public static void example4(){

BinaryOperator<Long> add = (Long x,Long y) -> x + y ;

System.out.println(add.apply(1L,2L));

}

 

public static void example5(){

BinaryOperator<Long> add = ( x, y) -> x + y ;

System.out.println(add.apply(1L,2L));

}
