چرا موقع استفاده از testContainers همیشه از اول ساخته میشه و در نتیجه با کندی مواجه می شویم ؟
💡 Concurrent Chaos List<Integer> list = new ArrayList<>(List.of(1,2,3)); for(Integer i : list) list.remove(i); // ConcurrentModificationException 😱
🔥 StringBuilder vs += Madness String s = ""; for(int i=0;i<1000;i++) s += i; // Slow & memory heavy 💡 Use StringBuilder for big loops!
💥 Null Pointer Surprise 💥 String s = null; System.out.println(s.length()); // Boom! 😱 NullPointerException
💥 Java “Surprise” Bug 💥 ``` List<Integer> list = new ArrayList<>(); list.add(1); list.add(2); list.add(3); for (Integer i : list) { list.remove(i); // Boom! 😱 } ``` Result? ConcurrentModificationException! Why? You can’t modify a list while looping over it.
💡 Java Tip: Stop using += in loops! Strings are immutable → each += creates a new object. ✅ Use StringBuilder for loops: faster & memory-friendly! #Java #CodingTips #Performance
