Scanner类

1、需要传参：System.in

2、scanner.next()接收字符串类型

3、scanner.nextInt()接收整型

package com.ke.demo1;

import java.util.Scanner;

public class demo1 {
    public static void main(String[] args) {
        Scanner scanner=new Scanner(System.in);
        System.out.println("输入姓名：");
        String name=scanner.next();
        System.out.println(name);
        System.out.println("输入年龄：");
        int age=scanner.nextInt();
        System.out.println(age);

    }
}
