Sometimes the difference between a flaky system and a reliable one is just a few lines of retry logic. Network calls fail, APIs timeout, and transient issues happen more often than we’d like to admit. Instead of scattering retry logic everywhere, here’s a small reusable utility with exponential backoff: // Simple retry utility with exponential backoff public static T retry(Supplier task, int maxAttempts) { int attempt = 0; long delay = 200; while (true) { try { return task.get(); } catch (Exception e) { if (++attempt >= maxAttempts) { throw e; } try { Thread.sleep(delay); } catch (InterruptedException ignored) {} delay *= 2; // exponential backoff } } Enter fullscreen mode Exit fullscreen mode } Why this works: Handles temporary failures (network hiccups, rate limits) Exponential backoff reduces pressure on downstream services Keeps your business logic clean and focused Usage example: String result = retry(() -> apiCall(), 3); Simple, effective, and saves you from a lot of random headaches in…
