 2     private int age;
 3     private String name;
 4     private int id;
 5     
 6     public Student(int age, String name) {
 7         super();
 8         this.age = age;
 9         this.name = name;
10     }
11     public int getAge() {
12         return age;
13     }
14     public void setAge(int age) {
15         this.age = age;
16     }
17     public String getName() {
18         return name;
19     }
20     public void setName(String name) {
21         this.name = name;
22     }
23     public int getId() {
24         return id;
25     }
26     public void setId(int id) {
27         this.id = id;
28     }
