Java 程序生成乘法表

在本文中，我们将了解如何打印乘法表。使用 for 循环迭代 10 次所需输入以创建乘法表，并在每次迭代中将输入值与 1 到 10 的数字相乘。

下面演示了相同的概念 −

输入

假设我们的输入为 −

Input : 16

输出

理想输出为 −

The multiplication table of 16 is :
16 * 1 = 16
16 * 2 = 32
16 * 3 = 48
16 * 4 = 64
16 * 5 = 80
16 * 6 = 96
16 * 7 = 112
16 * 8 = 128
16 * 9 = 144
16 * 10 = 160

算法

Step 1 – START
Step 2 – Declare two integer values namely my_input and i.
Step 3 - Read the required values from the user/ define the values
Step 4 – Iterate from 1 to 10 using a for-loop, and in each iteration, multiply the numbers 1 to
10 with the input.
Step 5- Display the resulting value in after each iteration.
Step 6- Stop

示例 1

在这里，用户根据提示输入输入。您可以在代码练习工具中亲身体验此示例 run button。

import java.util.Scanner;
public class MultiplicationTable {
   public static void main(String[] args) {
      int my_input, i;
      my_input = 16;
      System.out.println("Required packages have been imported");
      Scanner my_scanner = new Scanner(System.in);
      System.out.println("A reader object has been defined ");
      System.out.print("Enter a number : ");
      my_input = my_scanner.nextInt();
      System.out.println("The multiplication table of " +my_input + " is :");
      for(i = 1; i <= 10; ++i){
         System.out.printf("%d * %d = %d \n", my_input, i, my_input * i);
      }
   }
}

输出

Required packages have been imported
A reader object has been defined
Enter a number : 16
The multiplication table of 16 is :
16 * 1 = 16
16 * 2 = 32
16 * 3 = 48
16 * 4 = 64
16 * 5 = 80
16 * 6 = 96
16 * 7 = 112
16 * 8 = 128
16 * 9 = 144
16 * 10 = 160

示例 2

在这里，整数已经预先定义，并在控制台上访问和显示其值。

public class MultiplicationTable {
   public static void main(String[] args) {
      int my_input, i;
      my_input = 16;
      System.out.println("The number is defined as " +my_input);
      System.out.println("The multiplication table of " +my_input + " is :");
      for(i = 1; i <= 10; ++i){
         System.out.printf("%d * %d = %d \n", my_input, i, my_input * i);
      }
   }
}

输出

The number is defined as 16
The multiplication table of 16 is :
16 * 1 = 16
16 * 2 = 32
16 * 3 = 48
16 * 4 = 64
16 * 5 = 80
16 * 6 = 96
16 * 7 = 112
16 * 8 = 128
16 * 9 = 144
16 * 10 = 160
