代码模型:对象比较

 1 package cn.demo;
 2 class Person{
 3     private String name;
 4     private int age;
 5     public Person(String name,int age){
 6         this.name = name;
 7         this.age = age;
 8     }
 9     public boolean compare(Person per){
10         if(per == null){
11             return false;
12         }
13         if(this == per){
14             return true;
15         }
16         if(this.name.equals(per.name) && this.age == age){
17             return true;
18         }
19         return false;
20     }
21     public String getName() {
22         return name;
23     }
24     public void setName(String name) {
25         this.name = name;
26     }
27     public int getAge() {
28         return age;
29     }
30     public void setAge(int age) {
31         this.age = age;
32     }
33 }
34 public class Test {
35     public static void main(String[] args) throws Exception {
36    Person per2 = new Person("李洋",23);
37    Person per1 = new Person("李洋",23);
38     if(per1.compare(per2)){
39         System.out.println("是同一个对象。");
40     }else{
41         System.out.println("不是同一个对象 ");
42     }
43     }
44 }
结果:是同一个对象。
