Java程序可打印任意数量的乘法表
以下是一个Java程序，该程序接受用户的整数变量并输出该特定整数的乘法表。
示例
import java.util.Scanner;
public class MultiplicationTable {
public static void main(String args[]) {
System.out.println("Enter an integer variable :: ");
Scanner sc = new Scanner(System.in);
int num = sc.nextInt();
for(int i=1; i<= 20; i++) {
System.out.println(""+num+" X "+i+" = "+(num*i));
}
}
}输出结果
Enter an integer variable :: 17 17 X 1 = 17 17 X 2 = 34 17 X 3 = 51 17 X 4 = 68 17 X 5 = 85 17 X 6 = 102 17 X 7 = 119 17 X 8 = 136 17 X 9 = 153 17 X 10 = 170 17 X 11 = 187 17 X 12 = 204 17 X 13 = 221 17 X 14 = 238 17 X 15 = 255 17 X 16 = 272 17 X 17 = 289 17 X 18 = 306 17 X 19 = 323 17 X 20 = 340
