Runtime Error

What This Error Means

This error occurs when a method calls itself recursively without a proper base case, leading to excessive recursion and ultimately exhausting the stack.

Why It Happens

This error typically happens when a method is designed to recursively call itself, but the recursive calls do not eventually reach a base case that stops the recursion. As a result, the stack becomes overwhelmed with recursive calls, leading to a StackOverflowError.

How to Fix It

1. 1To fix this error, identify the method causing the recursion and ensure it has a proper base case to stop the recursion. Alternatively, consider using an iterative approach instead of recursion to avoid stack overflow issues. For example, if the recursive method is supposed to find the sum of all elements in a list, consider using a for loop instead.

Example Code Solution

public class Main {
	public static void main(String[] args) {
		System.out.println(findSum(new int[] {1, 2, 3, 4, 5}));
	}
	public static int findSum(int[] array) {
		if (array.length == 1) return array[0];
		else return array[0] + findSum(array);
	}

public class Main {
	public static void main(String[] args) {
		System.out.println(findSum(new int[] {1, 2, 3, 4, 5}));
	}
	public static int findSum(int[] array) {
		int sum = 0;
		for (int i = 0; i < array.length; i++) {
			sum += array[i];
		}
		return sum;
	}
