I attempted to create a calculator, but I can not get it to work because I don't know how to get user input.
How can I get the user input in Java?
One of the simplest ways is to use a
Scanner object as follows:
Scanner reader = new Scanner(System.in); // Reading from System.in System.out.println("Enter a number: "); int n = reader.nextInt(); // Scans the next token of the input as an int.
