如何在Java中创建一个包含可变数量参数的“除法”函数

Question

I want to ask a question how to create a "Division" function which contains variable number of parameters in Java? Just Like As I did for sum method:

    public static int sum(int ... x)
    {
        int sum=0;
        for(int i : x)
        {
            sum=sum+i;
        }
        return sum;
    }

Answer 1

Well, the difference is that you're gonna have to provide a number to divide as parameter:

public static int div(int div, int ... x)
{
   for(int i : x)
   {
      if(i > 0) div=div/i;
   }
   return div;
 }

Be careful to test if i is greater than 0, otherwise the compiler will throw an error, since you cannot divide by 0.
