Write a program that reads a single integer from the user using Scanner and prints it back with the message:

You entered: [number]

Create a Scanner object: Scanner scanner = new Scanner(System.in); and use scanner.nextInt() to read the integer.

⚠️ IMPORTANT - AUTO-INPUT MODE:
This question uses automated input testing. When you run your code, the input stream will AUTOMATICALLY contain: '42\n'

DO NOT wait for manual keyboard input - Scanner will read from the pre-filled buffer stream immediately. Your program should use Scanner methods like nextInt(), nextDouble(), or nextLine() to read these values directly.

Think of it like Eclipse/VS Code but with the input already typed in and waiting for your Scanner to read it.
