Java中List的几种遍历方式（含Java8）

首先在Android Studio中建立一个Class，代码如下

class Test {

public static ListmemberList =new ArrayList<>();

    public Test() {

}

public void addMember(int a){

for (int i =0 ; i <15; i ++){

memberList.add(a+i);

        }

}

public static void main(String[] args){

Test test =new Test();

        test.addMember(5);

        // 遍历第一种方法

        for (int x :memberList){

System.out.println(x);

        }

System.out.println("==============================");

        //遍历第二种方法

        for( Iterator itr =memberList.iterator(); itr.hasNext();){

int temp  = itr.next();

            System.out.println(temp);

        }

**System.out.println("==============================");

        //遍历第三种

        memberList.forEach(x->{System.out.println(x);});

    }

}

运行结果：
