How can I troubleshoot a StackOverflowError in Java?

A StackOverflowError typically arises from infinite recursion. To troubleshoot, examine your code for recursive method calls that lack a proper base case or termination condition. Also, check for excessive nesting of method calls. Use a debugger to step through the execution, identify the recursive calls, and analyze the call stack to pinpoint the cause. Refactor your code to avoid infinite recursion, either by changing the algorithm or reducing the stack usage.
