在Person类的基础上，添加一个带参数的构造函数，参数分别为姓名，性别，年龄，

[java]代码库

import java.util.Scanner;
public class Main{
	public static void main(String[] args) {
         Scanner scan = new Scanner(System.in);      
         String name = scan.next();      
         String sex = scan.next();      
         int age = scan.nextInt();
         Person p = new Person(name,sex,age);
         p.print();
         scan.close(); 
    }
} 
class Person{
	public String name;
	public String sex;
	public int age;
	
	public Person(String n, String s, int a) {
		name = n;
		sex = s;
		age = a;
	}
	public void print(){
		System.out.print("name:"+name+"; "+"sex:"+sex+"; "+"age:"+age);
	}
