从键盘读取数据（了解）

1.导包 ：import java.util.Scanner;
2.创建Scanner类的对象 : Scanner scanner = new Scanner(System.in);
3.调用Scanner类中的方法

import java.util.Scanner;
public class ScannerTest{

    public static void main(String[] args){
        
        //创建Scanner类的对象 : Scanner scanner = new Scanner(System.in);
        Scanner scanner = new Scanner(System.in);
        //调用Scanner类中的方法
        System.out.println("请输入您的成绩");
        int score = scanner.nextInt();

        System.out.println("请输入您的姓名");
        String name = scanner.next();

        System.out.println("请输入您帅不帅(true/false)");
        boolean handsome = scanner.nextBoolean();



        System.out.println("score=" + score);
        System.out.println("name=" + name);
        System.out.println("handsome=" + handsome);


    
    }
}
