还有分类可以分三类应该好理解一些

sb.append(b + "百");
}
}
int shi = num / 10 % 10;

int ge = num % 10;
String g = getNum1(ge);
if (!s.equals("零")) {

sb.append("十");
} else if(!g.equals("零")){
sb.append("零");
}
if (!g.equals("零")) {
sb.append(g);
}
return sb;
}
}

（方法getNum1（）可以用数组，会在减少一些代码）

import java.util.Scanner;

额、考虑不周，在十位数case 0:那里改一下应该就好了
if(bai != 0) {
      if(ge == 0) {
            System.out.print("");
      }else {
            System.out.print("零");
      }
}

方法一：int a =(int) (Math.random()*1000)+1 方法二：Random r = new Random(); int a = r.nextInt(1000)+1
