二、Java初级--7、setter和getter

加注释：“ctrl+/”，取消也是“ctrl+/”

this代表当前对象，谁来调用，谁就是此时的this

package javastudy;

public class Person {
    private String name;
    private int height;
    //setter
    public void setName(String name){
        this.name=name;  //实例对象z来调用setName，此时this即为z;实例对象w调用，this即为w
        
    }
    public void setHeight(int height){
        this.height=height;
    }
    //getter
    public String getName(){
        return name;
    }
    public int getHeight(){
        return height;
    }
}

package javastudy;

public class testit {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
//      z.name="zhang";
//      z.height=120;
        Person z=new Person();
        z.setName("zhang");
        z.setHeight(170);
        System.out.println(z.getName());
        System.out.println(z.getHeight());
        
        Person w=new Person();
        w.setName("wang");
        w.setHeight(200);
        System.out.println(w.getName());
        System.out.println(w.getHeight());
    }
}
