Thread: String Problem

I have a problem with Payroll program I want to input only a alphabet for the name , if the
user's input a number, for example, "sam4pl3" or "123 " the program will show a message "Number is not allowed" although the string is alphanumeric, then ask the user to input again, i

thanks in advance.

    public static void main(String[] args) {
        Scanner dataIn = new Scanner(System.in);
 
        String firstName;
        String middleName;
        String lastName;
 
	//NAME
	System.out.print("Employees First Name: ");
        firstName = dataIn.nextLine();  //input first name 
        System.out.print("Employees Middle Name: ");
        middleName = dataIn.nextLine(); //input middle name
        System.out.print("Employees Last Name: ");
        lastName = dataIn.nextLine();   //input last name
 
	Sample OUTPUT:
	 Employees First Name: Juan 4 you
	 Numbers are not allowed!
	 Employees First Name: Juan
	 Employees Middle Name: 143
  	 Numbers are not allowed!
	 Employees Middle Name: 54
