Help please about my index. I submitted and it said int cannot be converted to int[] index= i;

I don't know what task this is, but looking at your code, I'd guess the thing you want to change is your method signature:

public static int finMaxIndex(int[] array)

In brackets is what you supply/pass to the method. After static is what the method gives back/returns.

But my autolab wants my code to be public static int[] findMaxIndex(int[] Array). Could you show me how to fix my code if I keep static int[]???

Yes, but theres no need to return an int array.

public static int[] finMaxIndex(int[] array){
int[] newArray = new int[1];
		int max = array[0];

		for (i=0; i< array.length; i++){
			if(array[i] > max){
				max = array[i];
			}

		newArray[0] = max
		return newArray;
	}

But if it's required to return an array, I suggest you might be doing the task wrong. Does it ask to return more than one value if there is more than one max?

Yes it asks to return more one value if there is more than one max. I try to submit it and it gave me 0. That's weird tho

Well, yeah - if there's a possibility of more than one max you need different code.
