I would say it is the use of multiple Scanner objects. To get rid of them, you have multiple possibilities: 1) use a static field Scanner keyboard in the Painter class. 2) pass the Scanner object to the methods that use them 3) read all input in main and pass the values to the methods (if they need them)

It might be caused by creating two Scanners opening the same System.in stream. Don't instantiate new Scanner in the method when you already opened the stream with other one in the main body

remove the Scanner in roomArea() pass the already created one to the function. //call dim=roomArea(keyboard); //definition public static double roomArea(Scanner keyboard ) { //Scanner keyboard=new Scanner(System.in); double dim; System.out.print("Enter the total area of walls: "); dim=keyboard.nextDouble(); System.out.print("Dimension: "+dim+ "sq ft"); return dim; }
