JAVA this关键字

用法：

public class Test2{
    String name;
    String age;
    public void atc(String name2,String age2){
        this.name    =    name2;    //this.name是访问属性name,这句代表给属性name赋值
        this.age    =    age2;
    }
    public static void main(String[] args){
        Test2 Myclass    =    new    Test2();
        Myclass.atc("小红","17");
        System.out.println(Myclass.name);
        System.out.println(Myclass.age);
    }
}
