【JAVA学习笔记】10 - 键盘输入语句

一、键盘输入语句

        在编程中，需要接受用户输入的数据，需要一个扫描器（对象），就是Scanner

1.步骤

        1）导入该类的所在包，java.util.* ； import java.util.Scanner;

        2)创建该类对象（声明变量）；Scanner myScanner = new Scanner(System.in);

        3）调用里面的功能

        

                System.out.println("Pleas enter your name");
                Srting name = myScanner.next();//接受完整字符串
        
                System.out.println("Pleas enter your age");
                Srting age = myScanner.nextInt();//接受Int型

                System.out.println("Pleas enter your salry");
                Srting salry = myScanner.nextDouble();//接受double型

2.代码                ​​​​​

import java.util.Scanner;//
public class Input{
	public static void main(String[] args){ 
		Scanner myScanner = new Scanner(System.in);
		System.out.println("Pleas enter your name");
		String name = myScanner.next();

		System.out.println("Pleas enter your age");
		int age = myScanner.nextInt();

		System.out.println("Pleas enter your salry");
		double salry = myScanner.nextDouble();

		System.out.println("Name=" + name + '\t' + "Age=" + age 
		+ '\t' 	+ "Salry=" + salry+ '\t' );
	}
}
