java spring-boot stackoverflowerror recursion Java

I've looked through the documentation and I'm still confused about I'm trying to figure out I'm stuck trying to I've been banging my head against this for hours..... I'm working with a `StackOverflowError` when executing a recursive method in my Spring Boot application, particularly when the input size is large. The recursive method is supposed to process a tree structure, but it seems to unexpected result under certain conditions. Here's the relevant portion of my code: ```java public class TreeNode { private int value; private List<TreeNode> children; public TreeNode(int value) { this.value = value; this.children = new ArrayList<>(); } public void addChild(TreeNode child) { this.children.add(child); } public List<TreeNode> getChildren() { return children; } } public class TreeProcessor { public void processTree(TreeNode node) { System.out.println(node.value); for (TreeNode child : node.getChildren()) { processTree(child); } } } ``` When I call `processTree(rootNode)` where `rootNode` has a depth of around 1000, I'm getting the following behavior: ``` Exception in thread "main" java.lang.StackOverflowError at com.example.TreeProcessor.processTree(TreeProcessor.java:12) ... 5 more ``` I've tried increasing the stack size using the `-Xss` JVM option by running my application like this: ```bash java -Xss2m -jar myapp.jar ``` However, this didn't help significantly. I also looked into iterative approaches but couldn't implement them due to the nature of the tree structure. What would be the best way to handle this recursion to avoid the `StackOverflowError` while still maintaining readability? Is there a design pattern or a specific approach in Java that could help resolve this scenario effectively? What's the best practice here? Any help would be greatly appreciated! I appreciate any insights!
