implementing Implementing a Merge Sort that Handles Large Data Sets in Java - Memory Overflow Errors
I'm having trouble with I've been researching this but I'm optimizing some code but I just started working with I'm trying to implement a Merge Sort algorithm in Java to sort a large dataset of integers, but I'm running into memory overflow errors when the size of the dataset exceeds a certain limit..... My current implementation works well for smaller arrays, but when I attempt to sort an array of size over 10 million, I get an `OutOfMemoryError: Java heap space`. I've attempted to optimize my code by using in-place merging, but I'm still working with these issues. Here’s the code I've written so far: ```java public class MergeSort { public void sort(int[] array) { if (array.length < 2) return; int mid = array.length / 2; int[] left = new int[mid]; int[] right = new int[array.length - mid]; System.arraycopy(array, 0, left, 0, mid); System.arraycopy(array, mid, right, 0, array.length - mid); sort(left); sort(right); merge(array, left, right); } private void merge(int[] array, int[] left, int[] right) { int i = 0, j = 0, k = 0; while (i < left.length && j < right.length) { if (left[i] <= right[j]) { array[k++] = left[i++]; } else { array[k++] = right[j++]; } } while (i < left.length) { array[k++] = left[i++]; } while (j < right.length) { array[k++] = right[j++]; } } } ``` I’ve also tried increasing the heap size using the `-Xmx` flag, but it doesn't seem to solve the question entirely. Is there a more efficient way to handle large datasets with Merge Sort, or should I consider switching to a different sorting algorithm for large inputs? Any advice would be greatly appreciated! My development environment is Debian. Any advice would be much appreciated. I recently upgraded to Java 3.11. Hoping someone can shed some light on this. I recently upgraded to Java stable. I'd be grateful for any help. I'm coming from a different tech stack and learning Java. I'd really appreciate any guidance on this. For reference, this is a production microservice. Any advice would be much appreciated.
