Scanner keeps skipping input whist using nextInt() and loops

Question

I am using a while loop to make sure that the value entered to a scanner object is an integer as such:

while (!capacityCheck) {
        try {
            Sys         


        

Answer 1

Use the following:

while (!capacityCheck) {
        System.out.println("Capacity");
        String input = scan.nextLine();
        try {
            capacity = Integer.parseInt(input );
            capacityCheck = true;
        } catch (NumberFormatException e) {
            System.out.println("Capacity must be an integer");
        }
    }
