Day 13: Abstract Classes – Hacker Rank Solution

Problem:

Objective
Today, we will extend what we learned yesterday about Inheritance to Abstract Classes. Because this is a very specific object oriented concept, submissions are limited to the few languages that use this construct. Check out the Tutorial tab for learning materials and an instructional video.

Task
Given a Book class and a Solution class, write a MyBook class that does the following:

  • Inherits from Book
  • Has a parameterized constructor taking these  parameters:
    1. string 
    2. string 
    3. int 
  • Implements the Book class’ abstract display() method so it prints these  lines:
    1. , a space, and then the current instance’s .
    2. , a space, and then the current instance’s .
    3. , a space, and then the current instance’s .

Note: Because these classes are being written in the same file, you must not use an access modifier (e.g.: ) when declaring MyBook or your code will not execute.

Input Format

You are not responsible for reading any input from stdin. The Solution class creates a Book object and calls the MyBook class constructor (passing it the necessary arguments). It then calls the display method on the Book object.

Output Format

The  method should print and label the respective , , and  of the MyBook object’s instance (with each value on its own line) like so:

Title: $title
Author: $author
Price: $price

Note: The  is prepended to variable names to indicate they are placeholders for variables.

Sample Input

The following input from stdin is handled by the locked stub code in your editor:

The Alchemist
Paulo Coelho
248

Sample Output

The following output is printed by your display() method:

Title: The Alchemist
Author: Paulo Coelho
Price: 248

class MyBook extends Book{
    private int price;
    MyBook(String $title,String $author,int $price){
        super($title,$author);
        this.price=$price;
    }
 
    void display(){
        System.out.println("Title: "+title);
        System.out.println("Author: "+author);
        System.out.println("Price: "+price);

    }
}
class Book{
 String title;
 String author;
	/**
	 * @param $title
	 * @param $author
	 */
	public Book(String $title, String $author) {
		this.author=$author;
		this.title=$title;
	}
	
}

  6. En las estafas de inversiones a menudo le prometen que puede “ganar mucho dinero” con “riesgo cero”, y estas estafas suelen comenzar en los medios sociales o en aplicaciones o sitios de citas. Por supuesto que estas estafas también comienzan con un mensaje de texto, email o llamada. Y en las estafas de inversiones, la criptomoneda cumple un rol central de dos maneras: puede ser tanto para una inversión como para pagar. Tras el acuerdo, y a través del sistema de monederos que se utiliza con los bitcoins -una especie de cuenta corriente – comprador y vendedor han hecho la transacción en segundos. Ahora, explica Platero, “sólo hay que ir al notario a formalizar la compraventa”. Por supuesto, si aún no hay disponibles cajeros Bitnovo Bitcoin en tu región, ¿sabes que también hay otras formas de comprar bitcoin en efectivo?

    Con la ayuda de los botones VENDER y COMPRAR podemos ver dos precios para una criptomoneda determinada y, por supuesto, comprarla o venderla. El precio de compra se llama precio ASK y el precio de venta se llama precio BID. Por supuesto, las posiciones largas en criptomonedas se abren haciendo clic en COMPRAR y seleccionando el volumen de la transacción. Las posiciones cortas, cuando está ganando dinero cuando el precio del instrumento está cayendo, por supuesto, se abren haciendo clic en VENDER y seleccionando el volumen de la transacción.

    The structure of the legal situation of gambling is as clear when it comes to online casinos in Canada. Each province has their own laws concerning remote gambling and have their right to apply and enforce them in their province. With that said, the general view on the legality question is that online gambling is legal in Canada. To be safe you can research the current situation in your province but according to calvinayre, no player should get convicted of an offence outside of Canada (which applies to remote gambling). One of the best ways to make sure you’re choosing a legal and safe online casino in the US is by reading our operator reviews. We only recommend trusted online casinos that comply with all legal and regulatory requirements set out by the state it’s operating in and offer reliable and secure online gambling services, including a secured online site and trusted payment methods.

  8. The relatively slow pace of crypto adoption by the mainstream wealth industry has created space for new players, such as ZeroCap, to attempt to fill the gap in the market by offering crypto products to wealthy investors. Many governments have taken a hands-off approach to crypto, but its rapid ascent and evolution, coupled with the rise of DeFi, has forced regulators to begin crafting rules for the emerging sector. Regulations vary widely around the world, with some governments embracing cryptocurrencies and others banning them outright. The challenge for regulators, experts say, is to develop rules that limit traditional financial risks without stifling innovation. In contrast to cryptos, Central bank digital currencies (CBDC) are fully centralized, issued by a legal entity and bound by regulatory framework. On the contrary, crypto-currencies are decentralized, with a transaction ledger visible to all.

    However, the downside of not owning your Bitcoin is you cannot spend it or withdraw it to a private wallet. Also, this means users won’t have access to typical investing activities you’d find on other platforms like lending. The leading crypto brands in the UK are eToro and Coinbase. Learn what the Bitcoin Ordinals are, their history, their basic operation and everything that this technology can offer … You can buy bitcoin directly on crypto exchanges, bitcoin ATMs, P2P marketplaces or traditional brokers. Likewise, you can also sell bitcoin via any of these channels, with the exception of some bitcoin ATMs. However, you should bear in mind that you should sell Bitcoin as soon as possible once you have made the decision to sell. And with reason – BTC is highly volatile. You need to act fast to get the gains you want from any sale because its price can quickly roll over. A simple and fast process will be vital to you.
