verifying if sum of array is even or odd [duplicate]

Here I have a function that calculates the sum of the values of an array

public static String oddOrEven(int[] array) {
  String result;
   if (array.sum() % 2 = 0) {
     result = "even";
     return result ;
   } else {
     result = "odd";
     return result;
   }
}


public static void main(String[] args) {
  int[] myArray = {2,9,7,1,3};
  oddOrEven(myArray);  
}

But it shows an error saying "cannot find symbol"
