Answer 3

三个private属性
利用get set 获取与设置属性

public class User {

private String name;
private String sex;
private int age;
/**
* @param name
* @param sex
* @param age
*/
public User(String name, String sex, int age) {
super();
this.name = name;
this.sex = sex;
this.age = age;
}
/**
*
*/
public User() {
super();
}
/**
* @return the name
*/
public String getName() {
return name;
}
/**
* @param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* @return the sex
*/
public String getSex() {
return sex;
}
/**
* @param sex the sex to set
*/
public void setSex(String sex) {
this.sex = sex;
}
/**
* @return the age
*/
public int getAge() {
return age;
}
/**
* @param age the age to set
*/
public void setAge(int age) {
this.age = age;
}

}
