16
17     public People(String name, int age, String sex) {
18         super();
19         this.name = name;
20         this.age = age;
21         this.sex = sex;
22     }
23
24     public String getName() {
25         return name;

28     public void setName(String name) {
29         this.name = name;
30     }
31
32     public int getAge() {
33         return age;
34     }
35
36     public void setAge(int age) {
37         this.age = age;
38     }
39
40     public String getSex() {
