Java语言编写乘法口诀表

public class Demo01 {
    public static  void main(String[] args){
        Demo01MultiplicationTable();
}
//乘法口诀表的方法：
    public static void Demo01MultiplicationTable(){

        int i=1,j=1;
//        乘法口诀正三角
        for (i = 1; i <= 9; i++) {
            for (j = 1; j <= i; j++) {
                System.out.print(j+"*"+i+"="+i*j+" ");
            }
            System.out.println();
        }
        System.out.println("========================");
//        乘法口诀表倒三角
        for (i = 9; i >= 1; i--) {
            for (j = 1; j <= i; j++) {
                System.out.print(j+"*"+i+"="+i*j+" ");
            }
            System.out.println();
        }
    }
}
