I need help with: The following is a class definition for a simple Ebook. Two instance variables and one parameterless constructor are provided. Part 1: Write a second Java constructor that takes a String array of pages as input and sets the String array instance variable equal to the input. Continue to default the page number to zero. Part 2: Write a getter and a setter Java method for the current page number variable. The setter should check to make sure that the input is a valid page number and only update the variable if the new value is valid. Part 3: Write a getCurrentPage method that returns the String of the current page indexed by current_page. public class Ebook { private String[] pages; private int current_page; //constructor public Ebook() { this.pages = {"See Spot.", "See Spot run.", "Run, Spot, run."}; this.current_page = 0; } }
