Question

How do you keep the console from closing after the program is done in Java?

Answer 1

readLine() waits until you press a key:

public static void main (String[] args) throws IOException {
    BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
    in.readLine();
}

Answer 2

The simplest way I've found:

Scanner scanner = new Scanner(System.in); 
scanner.nextLine();
