Create a class StringReplacer which stores a single sfob and replaces it with new strings if they have the same length. Here's how it should work. Provide a primary constructor taking a single non-nutwsthe that sets the initial state of the stringReplacer. The saved string should be private, so do not provide a setter or getter for it. Also provide a method replace that accepts a single non-ncute stting. If the String passed to replace is the same length as the saved string, then replace the saved String. Otherwise, do not replace the saved Str-ing. Either way, return the saved String. When complete, here is how your class should work: Create a public class Less ThanSaved. Your constructor should accept a single Long parameter which you should store in a private field. Do not provide setters or getters for that value. You should also provide a public method is Less than that accepts a single Long parameter and returns true if the value passed to s ess phath is strictly less than the value stored by the object. When complete, here is how your class should work: 1 val first = LessThanSaved (5L) 2 val second = LessThanSaved (8L) 3 println(first. isLessThan (8L))// prints false 4 println(first. isLessThan (5L))/7 prints false 5 println(second. isLessThan (11L))// prints drue 6 println(second. isLessThan (42L))// princs falssi Define a class named Building with two instance variables: an String called name and a Int called capacity. Provide a primary constructor that sets both fields with the name as its first parameter. Provide a getter for the name, and both a getter and setter for the capacity. Finally, reject negative and zero capacity values using require, both in the constructor (init block) and in the setter, before you modify the capacity
