Hello, I've tried to pass an initialization list {...} to a constructor and it didn't work. When I instead declared it in a method local variable (int[]) it worked flawlessly. Why is that? public class QuickSort { int[] a; public QuickSort(int[] a) { this.a = a; } public static void main(String[] args) { //...
