对象作为参数和返回值（初学）

package day01;

public class Student {
    private String name;
    private int age;

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

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

    public void setAge(int age) {
        this.age = age;
    }
    public void hi(String name,int age){
        System.out.println("我叫"+name+"今年"+age);
        System.out.println("我叫"+this.name+"今年"+this.age);
    }
}

package day01;

public class Case04 {
    public static void main(String[] args) {
        /*Student stu1=new Student();
        stu1.setName("Lucken");

        method(method01());
    }
    public static void method(Student stu){
