类对象作为输入参数

package org.example;
import java.util.Arrays;public class Main
{public static void main(String[] args){stu stu1=new stu();stu1.say();change(stu1);//类对象作为输入参数System.out.println(stu1.name);stu1.say();}public static void change(stu s){s.name="全局可修改";}
}
class stu {String name;public void say(){System.out.println(this.name+"xuesheng");}
}
