Learn how to create a class in Scala. When you create a class in Scala, it automatically creates a primary constructor and the getter/setter methods for any fields declared in the class.
- In Scala when we create a class…it automatically creates a primary constructor…and the corresponding getter and setter methods…for any fields declared in the class.…In your exercise files folder, chapter 04 > 04_01…you'll have a starting program called payroll.scala.…It's just a template that you see here…that has the payroll extends app.…What we're going to do, is we're going to add a class,…so when you're dealing with payroll…you're dealing with employees.…So we're going to add a class to represent an employee…and then in our payroll in our main method there…we're going to create some employees…and print out their information.…
Let's start by adding the class.…I'm going to put it down here below my object for payroll…and I use the keyword class all in lowercase letters…and in this case I'm going to call it employee.…And then in the parameters we're…going to need some information about the employee,…we're going to need to know what is their first name…and that's going to be of type string.…We'll need to know their last name…
