蓝桥杯算法提高VIP-输出九九乘法表-题解（Java代码）水经验水经验

解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
                Scanner scanner=new Scanner(System.in);     
                        System.out.println("  Nine-by-nine Multiplication Table");
                        System.out.println("--------------------------------------");
                        System.out.println("     1   2   3   4   5   6   7   8   9");
                        System.out.println("--------------------------------------");
                        for(int i=1;i<=9;i++) {
                            System.out.printf("%2d",i);
                            for(int j=1;j<=9;j++) {
                                System.out.printf("%4d",i*j);
                                if(j==i) //根据每行规律能看出，当i与j相等的时候就不再输出乘积，终止本次循环。
                                    break;
                            }
                            System.out.println();
                        }
                        System.out.println("--------------------------------------");                          
    }
