Create a class book with two private int fields, numpages and currentpage. supply a constructor that takes one parameter and sets numpages to that value and currentpage to 1. provide accessor methods for both fields. also provide a method nextpage that increments currentpage by 1, but only if currentpage is less than numpages.

The code is in the explanation.

Explanation:

/*Creating the class*/

public class Book{

      /*Here we put the attributes of the class;

      In our case, they are the two private ints*/

      private int numPages;

      private int currentPage;

    /*Here is the constructor.

    The constructor always has the same name as the class

     In (), are the parameters.*/

     public Book(int numberOfPages){

                numPages = numberOfPages; /*sets numPages to the value

                                                                    of the parameter*/      

               currentPage = 1; /*sets currentPage to 1*/    

}

   /*An acessor method is a method with which we can get the value of a      variable*/

    /*Acessor method for numPages*/

   /*numPages is an int, so the acessor method returns an int*/

    public int getnumPages(){

            return numPages;

    }

    /*Acessor method for currentPage*/

    public int getcurrentPage(){

           return currentPage;    

     }

     /*Method next page*/

     /*This method does not return anything, so it is a void method*/

     public void nextPage(){

     /*Verify that currentPage is less than numPages*/

     if (currentPage < numPages){

             currentPage = currentPage + 1;

     }

     }

}
