根据键盘录入的数据输出对应的乘法表:

import java.util.Scanner;
class Hello2 {
    public static void main(String[] args) {
         Scanner sc = new Scanner(System.in);
         System.out.println("请输入一个1-9的整数");
         int x = sc.nextInt();
         print(x);
    }

    public static void print(int a) {
        for(int i = 1;i <=a;i++) {
           for(int j = 1;j <=i;j++) {
              System.out.print(j + "*" + i + "=" + (i * j) + '\t');
           }
           System.out.println();
        }
    }
}

结果:
