When I use a Scanner to read input from user several times, there is a problem with the next print line. With this simple code: Scanner sc = new Scanner (System.in); System.out.println("Introduce first number"); int number1 = sc.nextInt(); System.out.println("Introduce second number"); int number2 = sc.nextInt(); When I run it, appears the first string and wait: Introduce the first number _ If I enter 12 for example and press enter, then appears the second string and then my input number and las wait for the second number: Introduce first number Introduce second number 12 _ It only happen in Linux (not in MacOS nor Windows). I use Linux Mint distribution. I think that is a synchronization thread problem because if I put a Thread.sleep before the first nextInt() all works fine.
