Question

我很想知道如何在用户给出的特定范围内生成垂直数字列表。

假设我有一个用户输入一个低数字和一个高数字，我想显示这些数字和这些数字之间的每个数字。

import java.util.Scanner; 

public class Table {

public static void main(String[] args) {
    //Create Scanner
    Scanner input = new Scanner(System.in); 

    //Prompt user to enter low number 
    System.out.println("Enter the low number ");
    int lowNumber = input.nextInt(); 

    //Prompt user to enter high number 
    System.out.println("Enter the high number");
    int highNumber = input.nextInt(); 

    //Create table
    for (int i = 1; i <=256; i++){
        System.out.print(i);
    }

你可能会说，我很丢失。

Answer 1

IntStream.range(lowNumber, highNumber).forEach(i -> System.out.println(i));

Answer 2

以下是其中一种方式：

import java.util.Scanner;

public class Table {

    public static void main(String[] args) {
        //Create Scanner
        Scanner input = new Scanner(System.in);

        //Prompt user to enter low number 
        System.out.println("Enter the low number ");
        int lowNumber = input.nextInt();

        //Prompt user to enter high number 
        System.out.println("Enter the high number");
        int highNumber = input.nextInt();
        System.out.println();

        //Create table
        for (int i = lowNumber; i <= highNumber; i++) {
            System.out.println(i);
        }

    }
}

<强>输出：

Enter the low number 
15
Enter the high number
20

15
16
17
18
19
20
