You can create a Scanner object try reading from console `Scanner scanner = new Scanner(System.in); scanner.nextLine();` Instead of doing `console.readLine();` — dev, Jul 25 '15 at 08:51

It's because there is no console available.

From, System.console() documentation

Returns: The system console, if any, otherwise null.

It returns the console only if there's one. And not always there is a console.

For Eg: While running the code from Eclipse, you won't find a console and hence calling System.console() would return null.
