Java 8 Lambda表达式-接口实现

Java 8 Lambda表达式在只有一个方法的接口实现代码编写中，可以起到简化作用：

(argument list) -> body

具体看Runnable接口的例子

public class RunnableLambdaTest {public static void main(String[] args) {System.out.println(Thread.currentThread().getName() + ": RunnableTest");//java 8之前的匿名类方法Runnable task1 = new Runnable() {@Overridepublic void run() {System.out.println(Thread.currentThread().getName() + " is running");}};Thread thread2 = new Thread(new Runnable() {@Overridepublic void run() {System.out.println(Thread.currentThread().getName() + " is running");}});//Lambda表达式编写Runnable实现类Runnable task3 = () -> {System.out.println(Thread.currentThread().getName() + " is running");};Thread thread4 = new Thread(() -> {System.out.println(Thread.currentThread().getName() + " is running");});Thread thread1 = new Thread(task1);thread1.start();thread2.start();thread4.start();new Thread(task3).start();} }
