Java中多重参数对我不起作用

Question

I am trying run this code but its not working for me to get multiple arguments.

public class apples {


public static void main (String []args) {
    System.out.println( average(43,56,76,4,32,3));
}
    public static int average(int...numbers){
        int total = 0;
        for (int x:numbers){
            total +=x;
            return total/numbers.length;
        }
  }

 }

Answer 1

you want return statement

return total/numbers.length;

out of loop

Answer 2

You need to put the return statement outside the for loop:

public static int average(int... numbers)
{
    int total = 0;
    for (int x : numbers) {
        total += x;

    }
    return total / numbers.length;
}

This is because if you pass 0 arguments to the method average() you won't never enter the body of the for loop. So the method won't reach a return statement.
