Java无法为我的简单程序找到符号

Question

package myfirstprogram;

import static java.lang.System.in;


import java.util.Scanner;
public class MyFirstProgram {


    public static void main(String[] args) {

        //get the users name
        Scanner sc = new Scanner(System.in);
        System.out.println("Please Enter Your Name");
        String name;
        name = sc.nextLine();

        //get the users age
        System.out.println("Please Enter Your Age ");
        ***int age = in.nextInt();***

        //Print out information 
        System.out.println("Hello" + name + ", you are" + age + "years old.");

    }

}

Java说无法找到“int age”的符号其他一切正常，但它不会运行：/

Answer 1

//让用户年龄

  System.out.println("Please Enter Your Age ");
    ***int age = in.nextInt();***

改为使用int age = sc.nextInt();
