[FIXED] System.console() gives a NullPointerException in NetBeans

Issue

I have the following problem: method readLine() or nextLine(), nextInt(), etc. throw an exception: NullPointerException.

I use the NetBeans IDE (if it matters).

public static void Reading()
{
    String qq;
    qq = System.console().readLine();
    System.console().printf(qq);
}

Solution

Some IDEs don't provide a console. Note that System.console() returns null in these cases.

From the documentanion

Returns:

     The system console, if any, otherwise null.

You can always use System.in and System.out instead, as follows:

String qq;
Scanner scanner = new Scanner(System.in);
qq = scanner.nextLine();
System.out.println(qq);
