Book.java

public class Book { private String title; private String author; private int numberOfRatings; private int totalRating; private float price; private boolean hasHardCover; public Book(String title, String author){ this.title = title; this .author = author; numberOfRatings = 0; totalRating = 0; price = (float) (Math.random()*10); hasHardCover = false; } public Book (String title, String author, float price, boolean hasHardCover){ this.title = title; this .author = author; numberOfRatings = 0; totalRating = 0; this.price = price; this.hasHardCover = hasHardCover; } public void addRating(int rating){ totalRating += rating; numberOfRatings ++; } public float findAvgRating() { if (numberOfRatings == 0) return 0; return ((float)totalRating)/numberOfRatings; } public String bookRecommendation(){ float avgRating = findAvgRating(); if (avgRating>=3 && avgRating<=4) return "Strongly Recomended"; if (avgRating >= 2 && avgRating <3) return "Recommended"; else if (avgRating >=1 && avgRating<2) return "Not Recommended"; else if (avgRating == 0) return "No Information Is Available For Recommendation"; return "UNEXPECTED DAATA FOUND"; } @Override public String toString(){ return "Book title: " + title + " Book author:" + author + " Number of ratings: " + numberOfRatings + " Avg rating: " + findAvgRating() + " Price: " + price + " " + bookRecommendation(); } }
