法律Java 程式生成乘法表
在本文中，我們將瞭解如何列印乘法表。使用 for 迴圈迭代 10 次所需輸入以建立乘法表，並在每次迭代中將輸入值與 1 到 10 的數字相乘。
下面演示了相同的概念 −
輸入
假設我們的輸入為 −
Input : 16
輸出
理想輸出為 −
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
演算法
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
在這裡，使用者根據提示輸入輸入。您可以在程式碼練習工具中親身體驗此示例 
。
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);
}
}
}輸出
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
在這裡，整數已經預先定義，並在控制檯上訪問和顯示其值。
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);
}
}
}輸出
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
