Java8中Lambda表达式的10个例子 
例1 用Lambda表达式实现Runnable接口 

//Before Java 8:
new Thread(new Runnable() {
@Override
public void run() {
    System.out.println("Before Java8, too much code for too little to do");
}
}).start();
//Java 8 way:
new Thread( () -> System.out.println("In Java8, Lambda expression rocks !!") ).start();

输出: 
too much code, for too little to do 
Lambda expression rocks !! 
这个例子使我们学到了java8中Lambda表达式的书写方式： 
(参数) -> 表达式 
(参数) -> 语句 
(参数) -> { 语句 }
