1 导入Scanner类在使用Scanner类的时候，我们需要先导入Scanner包。2 ①打开我们的Eclipse。②新建一个Java项目(Java Project)、包(Package)和类(Class)。③在自动生成代码的第一行的下面(package xxx;)输入一行新代码:import java.util.Scanner;(导入java.util.Scanner包)3 一如既往的在public class xxx;下一行...
Scanner 类在 java.util 包中,因此需要在代码中使用 import 语句导入该包。 下面是一个使用 Scanner 类从键盘接收输入的简单示例: import java.util.Scanner; public class ScannerTest { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("请输入一个...
