面向对象this关键字的内存图解

//定义老师类
class Teacher {
    private String name;
    private int age;

    public String getName(){
        return name; 
        //return this.name;这里隐含了this,
        //因为局部没有name变量，所以不需要写this
    }

    public int getAge(){
        return age;
    }

    public void setName(String name){
        this.name = name;
    }

    public void setAge(int age){
        this.age = age;
    }

}

class Test{
    public static void main(String[] args){
        Teacher t = new Teacher();
        t.setName("张三");
        t.setAge(23);
        System.out.println(t.getName() + "---" + t.getAge());

        Teacher t2 = new Teacher();
        t2.setName("李四");
        t2.setAge(30);
        System.out.println(t2.getName() + "---" + t2.getAge());
    }
}

张三---23
李四---30
