How to get the top 5 numbers from a 2D array of random numbers

I am pretty new to java and am just learning 2D arrays. I am trying to get the top 5 numbers to display from a random list. I think this could work but am not sure why I am getting an error. One other thing is that I cannot use the sort function.

Code here:

public static void main(String[] args) {
 //Random Number stuff
        Random rand = new Random();
        
        int[] large = new int [5];
        
        int max = 0, index;

        int[][] arrSize = new int [4][5];
        
        
        for (int i = 0; i < arrSize.length; i++) {
            for (int j=0; j< arrSize[i].length; j++) {
                arrSize[i][j] = rand.nextInt(89) + 10;
                
                System.out.print(arrSize[i][j] + " ");
            }
                
            System.out.println();
            
        }
        // Top 5
        for (int p = 0; p < 5; p++) {
        max = arrSize [0][0];
        index = 0;
        
        for (int i = 0; i < arrSize.length; i++) {
            for (int j = 0; j < arrSize[i].length; j++) {
                
                if (max < arrSize[i][j]) {
                    
                    max = arrSize[i][j];
                    index = i;
                    
                }
        }
        }
        
        
        large[p] = max;
        arrSize[index] = Integer.MIN_VALUE;  //Error here
        
            System.out.println("Highest Number: " + large[p]);
    }
 
}
}

Exception in thread "main" java.lang.Error: Unresolved compilation problem:

I am not sure why I am getting an error, any help would appreciated. If anyone else has any answers for how I could get the top 5 in a different way that would also be appreciated.
