java編寫乘法口訣表

很簡單，直接上代碼

 

class  Demo{
 public static void main(String[] args)
 {for(int i=1;i<=9;i++){
          for(int b=1;b<=i;b++){
              if(i*b<=9)
               System.out.print(b+"*"+i+"="+i*b+"  ");
   else
                System.out.print(b+"*"+i+"="+i*b+" ");
    }
           System.out.println();
  }
      }
}
