java - Return the index of the largest number in the array -

question: write method called largest takes array nums3 parameter. finds largest of numbers in array , returns index value of method.

so know if return largest, that's value, how can return i, index? when compile, error: cannot find symbol i.

public static int largest(int[] nums3) {     int largest = nums3[0];     for(int i=0; < nums3.length; i++)     {         if(nums3[i] > largest)         {             largest = nums3[i];         }          }     return i; } 

one way can saving largest index, not value. need return value in case of empty array:

public static int largest(int[] nums3) {     if (nums3.length == 0) { return -1; }      int largestindex = 0;     for(int i=0; < nums3.length; i++)     {         if(nums3[i] > nums3[largestindex])         {             largestindex = i;         }      }     return largestindex; }
