代码模型:对象比较

package cn.demo;
class Person{
    private String name;
    private int age;
    public Person(String name,int age){
        this.name = name;
        this.age = age;
    }
    public boolean compare(Person per){
        if(per == null){
            return false;
        }
        if(this == per){
            return true;
        }
        if(this.name.equals(per.name) && this.age == age){
            return true;
        }
        return false;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
}
public class Test {
    public static void main(String[] args) throws Exception {
   Person per2 = new Person("李洋",23);
   Person per1 = new Person("李洋",23);
    if(per1.compare(per2)){
        System.out.println("是同一个对象。");
    }else{
        System.out.println("不是同一个对象 ");
    }
    }
}

结果:是同一个对象。
