Handle stack overflow exception in a endless recursive call

Question

I have a situation like below

class a{
    public void process(){
      System.out.println("ABC");
      process();
    }
}

while I'm executing at certain point I'm getting stack overflow exception. On my situation I can't change the recursive call logic. So for a work around I try to catch the error and made a gc call again initiate the process() method. Whether is it a good solution... or what is the better solution to keep the recursive call alive infinitely.

Answer 1

Your recursive call uses up a stack frame in the JVM each time recursion occurs, making a stack overflow error inevitable.

The best solution in Java is to use iteration instead. For example:

public void process() {
    while (true) {
        processOnce();
    }
}
