首先导入Scanner类：import java.util.Scanner;接着创建一个Scanner对象：Scanner input = new Scanner(System.in);然后使用nextInt()方法读取用户输入的整数：int userNum = input.nextInt();这里，nextInt()方法的作用是读取用户输入的一个整数，并将其存储在userNum变量中。如果用户输入的不是整数，...
4. Using the Console Class for Input and Output In JDK 6 and later, we can use the Console class from java.io package to read from and write to the console. To obtain a Console object, we’ll call System.console(): Console console = System.console(); Next, let’s use th...
