help me to solve this problem..
Given below is a class definition for Book. Type and compile the class, and answer the following questions:
class Book {
String title; //bookâ??s title
double price; //bookâ??s price
public Book(String t, double p) {
title = t;
price = p;
}
public String getTitle() {
return title;
}
public double getPrice() {
return price;
}
}
Write a program in a class TestBook that can do the following:
Read an integer, n (representing the number of books), from the keyboard and then create an array name myLibrary of type Book with size n.
Using loop, create n objects of type Book and put them in the array myLibrary after reading the title and price for each book from the keyboard.
Print out the title of the book with the highest price.
Print out all titles of books that contain the term â??Javaâ?? in their title.

Hi Friend,
Try this:
import java.util.*;
class Book{
String title;
double price;
public Book(String t, double p) {
title = t;
price = p;
}
public String getTitle(){
return title;
}
public double getPrice(){
return price;
}
}
public class BookInformation{
public static void main(String[]args){
Scanner input=new Scanner(System.in);
System.out.println("Enter no of books: ");
int n=input.nextInt();
Book myLibrary[]=new Book[n];
for(int i=0;i<myLibrary.length;i++){
System.out.print("Title: ");
String title=input.next();
System.out.print("Price: ");
double price=input.nextDouble();
myLibrary[i]=new Book(title,price);
}
double max = Double.MIN_VALUE;
for(int i=0;i<myLibrary.length;i++){
if(myLibrary[i].getPrice() > max) {
max = myLibrary[i].getPrice();
}
}
for(int i=0;i<myLibrary.length;i++){
if(myLibrary[i].getPrice()==max){
System.out.println(myLibrary[i].getTitle()+"-"+myLibrary[i].getPrice());
}
}
for(int i=0;i<myLibrary.length;i++){
int index=myLibrary[i].getTitle().indexOf("Java");
if(index>=0){
System.out.println(myLibrary[i].getTitle());
}
}
}
}
Thanks
