 案例一

1
class Multiplication{ 2 public static void main(String args[]){ 3 String Str = "9 9 乘法表\n"; 4 Str += "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n"; 5 System.out.println(Str); 6 for(int i=1;i<10;i++){ 7 for(int j=1;j<=i;j++){ 8 //打印乘法表 9 System.out.print(j+"×"+i+"="+i*j); 10 //添加逗号 11 if(i!=j){ 12 System.out.print(","); 13 } 14 } 15 //每打印一行输出一个换行符 16 System.out.print("\n"); 17 } 18 } 19 }
