建一个Person类

 1 package demo05;
 2 
 3 import java.io.Serializable;
 4 
 5 public class Person implements Serializable {
 6     private String name;
 7     private int age;
 8     //private transient int age; 阻止成员变量序列化
 9     
10     public Person(String name, int age) {
11         super();
12         this.name = name;
13         this.age = age;
14     }
15     public Person() {
16         super();
17     }
18     
19     public String getName() {
20         return name;
21     }
22     public void setName(String name) {
23         this.name = name;
24     }
25     public int getAge() {
26         return age;
27     }
28     public void setAge(int age) {
29         this.age = age;
30     }
31     
32     @Override
33     public String toString() {
34         return "Person [name=" + name + ", age=" + age + "]";
35     }
36     
37 }
