JAVA Help Please!!

public class Sorting { public static void main(String[] args) { // Example input. int numbers[] = {10, 2, 78, 4, 45, 32, 7, 11}; int i;

int numbersSize = numbers.length; // Print array pre sorting. System.out.print("UNSORTED: "); for (i = 0; i < numbersSize; i++) { System.out.print(numbers[i] + " "); } System.out.println();

// Run Insertion Sort. insertionSort(numbers);

// Print array post sorting. System.out.print("SORTED: "); for (i = 0; i < numbersSize; i++) { System.out.print(numbers[i] + " "); } System.out.println(); }

public static void insertionSort(int numbers[]) { for (int i = 1; i < numbers.length ; i ++ ) { int j = i; while(j > 0){

if (numbers[j] < numbers[j-1]) { int temp = numbers[j]; numbers[j]= numbers[j-1]; numbers[j-1] = temp; j--; } else{ break; } } } } }

Q. How should I edit this so that

"Tests the array being a null value, should immediately return out of method."

???
