hi complete noob in programming and am trying to do some user input validation using a System.in scanner i am trying to find a way to detect when a user inputs nothing and just presses the enter key but it seems like java doesn't acknowledge the enter key as an input because when i run the program and press enter the text cursor on the console just moves to a new line and the program acts like it is still waiting for an input so how would i detect when the enter key is pressed?
side question is pressing the enter key the same as no input or is it classes as input?
If you're using an instance of Scanner(System.in),
pressing the enter key, scanner.nextLine()
without a previous input should return an empty string.
