Ah I just figured out my error, sorry guys. What a simple mistake, I feel retarded.

You can also try the following code:

import java.util.*;

 class Book{
    String author;
    String title;
    String summary;
    public Book(String author,String title,String summary){
    this.author=author;
    this.title=title;
    this.summary=summary;
    } 
    public String getTitle(){
        return title;
    }
    public String getAuthor(){
        return author;
    }
    public String getSummary(){
        return summary;
    }
}
public class BookInformation{
    public static void main(String[]args){
        Scanner input=new Scanner(System.in);
        Book myLibrary[]=new Book[6];
        for(int i=0;i<myLibrary.length;i++){
        System.out.print("Author: ");
        String author=input.nextLine();
        System.out.print("Title: ");
        String title=input.nextLine();
        System.out.print("Summary: ");
        String summary=input.nextLine();
        myLibrary[i]=new Book(author,title,summary);
        System.out.println();
        }
        System.out.println();
        System.out.println("Book Information");

        for (int i = 0; i < myLibrary.length; i++){
            Book library = myLibrary[i];
            System.out.println(library.getAuthor() + "\t "+ library.getTitle() + "\t "+ library.getSummary() + "\t ");
        }
        System.out.println();
        System.out.print("Enter title to search infomation: ");
        String tit=input.nextLine();
        System.out.println();
        for(int i = 0; i <  myLibrary.length; i++) {
            if(tit.equals(myLibrary[i].getTitle())) {
                System.out.println("Author is: "+myLibrary[i].getAuthor());
                System.out.println("Summary is: "+myLibrary[i].getSummary());
            }
        }
     }   
}
