Java:九九乘法表!

1.下三角形

代码:

package day;
import java.util.Scanner;
public class Day0506 {
//九九乘法表(下三角)
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner sc = new Scanner(System.in);
		int i , j;
		for(i = 1 ; i <= 9 ; i++) {
			for(j = 1 ; j <= i ; j++) {
				System.out.print(j+"*"+i+"="+(i*j)+"  ");
			}
			System.out.print("n");
		}
	}
}

2.上三角形

代码:

package day;
import java.util.Scanner;
public class Day0505 {
//九九乘法表(上三角)
public static void main(String[] args) {
	// TODO Auto-generated method stub
	Scanner sc = new Scanner(System.in);
	int i , j;
	for(i = 9 ; i >= 1 ; i--) {
		for(j = 1 ; j <= i ; j++) {
			System.out.print(j+"*"+i+"="+(i*j)+"  ");
		}
		System.out.print("n");
	}
}
}
