I'm trying to check for empty strings with a Scanner and I'm not sure how to loop it so that it asks for the correct input.
So I want to use
System.out.print("Enter your First Name: "); String employeeFirstName = j.next(); //first name declared System.out.print("Enter your Last Name: "); String employeeLastName = j.next(); //last name declared
and I want to have it check so if the user enters a number or a blank that it asks for the input again. I tried using both if and while loops and it would still print "enter last name" after the first name and then also say it was invalid and crash the program.
