Create a public class named Restaurant. Restaurant should store two pieces of data: a name $($as a String?$)$ using the property name and a capacity $($as an Int$)$ using the property capacity. Provide a constructor that allows both fields to be set, with the name first. Design your class so that it provides both a setter and a getter for the capacity but only a getter for the name. Finally, reject negative and zero capacity values and null names. kotlin
