Here's Simple Java.8 Solution :

import java.util.*; abstract class Book{ String title; abstract void setTitle(String s); String getTitle(){ return title; } } class MyBook extends Book{

@Override
void setTitle(String s) {
    this.title = s;
}

} //Write MyBook class here

public class Main{

public static void main(String []args){
    //Book new_novel=new Book(); This line prHMain.java:25: error: Book is abstract; cannot be instantiated
    Scanner sc=new Scanner(System.in);
    String title=sc.nextLine();
    MyBook new_novel=new MyBook();
    new_novel.setTitle(title);
    System.out.println("The title is: "+new_novel.getTitle());
    sc.close();

//This code runs for all the test cases
import java.io.*;
import java.util.*;

abstract class Book{
    String title;
    abstract void setTitle(String s);
    String getTitle(){
        return title;
