Java Arrays.fill() negative number

Question

I am trying to fill a 2D array with '-1' as all the values. The code that I'm using is:

int c [] []=new int[4][4];
Arrays.fill(c,-1)

This throws the following error:

Exception in thread "main" java.lang.ArrayStoreException: java.lang.Integer

Can anyone please tell me what's wrong in the code?

Its an array of array of Integer.

You should write

    int c [] []=new int[4][4];
    for(int[] arr : c){
        Arrays.fill(arr,-1);
    }
