java程序设计 应急，各位大侠帮帮忙！

定义一个人类，包含姓名，性别，年龄等。所有的变量必须私有，其他类只能通过该类方法获取和修改。实例化一个人类，并通过该类的方法修改实例化的人的信息。

Answer 1

public class Person{
private String username;
private String sex;
private int age;

public void setUsername(String username){
this.username = username;
}
public String getUsername(){
return username;
}

public void setSex(String serx){
this.sex = sex;
}
public String getSex(){
return sex;
}
public void setAge(int age){
this.age = age;
}
public int getAge(){
return age;

private int age;
public String getName(){
return this.name;
}
public void setName(String name){

Answer 5

public class Person
{
private String name;
private int age;
private String sex;

Person(String name,int age,String sex)
{
this.name=name;
this.age=age;

}
pubilc void printPer()
{
System.out.print(name+" "+age+" "+man);
System.out.println();
}

}
class PersonDemo
{
public static void main(String[] args)
{
Person person=new Person("name",20,"man");
person.printPer();
}
}
