help me to solve this problem..

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
