Most Used Functions in Java! 🔥

Learn the most important Java functions with examples! 🧑‍💻💡

📌 Basic Operations: ✅ Add two numbers → int sum = a + b; ✅ Find average → double avg = (a + b) / 2.0; ✅ Count elements in an array → array.length

📌 Math Functions: ✅ Max value → Math.max(a, b); ✅ Min value → Math.min(a, b); ✅ Square root → Math.sqrt(n); ✅ Power of a number → Math.pow(base, exp);

📌 Conditions & Loops: ✅ IF condition → if (condition) { ... } ✅ Sum with condition → Arrays.stream(arr).filter(n -> n > 10).sum(); ✅ Count with condition → Arrays.stream(arr).filter(n -> n > 10).count();

📌 String Functions: ✅ Concatenate → String result = str1 + str2; ✅ Convert to uppercase → str.toUpperCase(); ✅ Convert to lowercase → str.toLowerCase(); ✅ Extract substring → str.substring(2, 5); ✅ Replace text → str.replace("old", "new"); ✅ Trim spaces → str.trim();

📌 Array & List Operations: ✅ Sort array (ascending) → Arrays.sort(arr); ✅ Sort array (descending) → Arrays.sort(arr, Collections.reverseOrder()); ✅ Reverse an array → Collections.reverse(Arrays.asList(arr)); ✅ Convert list to array → list.toArray(new Integer[0]); ✅ Convert array to list → Arrays.asList(arr);

📌 Number Functions: ✅ Check even/odd → (num % 2 == 0) ✅ Find factorial → factorial(n) { return (n == 0) ? 1 : n * factorial(n - 1); } ✅ Check prime number → isPrime(n) { for (int i = 2; i <= Math.sqrt(n); i++) { if (n % i == 0) return false; } return true; } ✅ Generate random number → new Random().nextInt(100);

📌 Date & Time: ✅ Get current time → System.currentTimeMillis(); ✅ Get current date → LocalDateTime.now(); ✅ Format date → new SimpleDateFormat("yyyy-MM-dd").format(new Date());

📌 File Handling: ✅ Write to file → Files.write(Paths.get("file.txt"), text.getBytes()); ✅ Read from file → new String(Files.readAllBytes(Paths.get("file.txt")));

📌 Other Useful Functions: ✅ Swap two numbers → int temp = a; a = b; b = temp; ✅ Sleep (pause execution) → Thread.sleep(1000); ✅ Generate UUID → UUID.randomUUID().toString();
