1) What is an API?
An API (Application Programming Interface) defines the possible interactions with a software component. It includes information on WHAT you can do and HOW you can make it do it. But doesn’t explain what happens inside.

2) In the article the author compares Java API to Twitter API. What is the main difference between these two APIs?
TwitterAPI is a web-based API, used to interact with the public data of twitter (example: Check how much likes you have) data is sent in JSON

JavaAPI is a library with a list of components that are regulary used, making the programmers life easier

3) The section in the article about abstraction is important, try to understand it and write down an abstraction from your daily life.
You can buy energy drinks ready made saving you the hassle of mixing water and powder. (in this case the powder is also an abstraction, the powder is ready made. You don’t have to go out and buy every ingredient separate, grind it up weigh it out, …)

  1. An API (application programming interface) is essentially the input layer resting between humans and computers that allows them to communicate to each other in powerful ways. Essentially we can tell a computer what to do and it does it like a perfect pet.

  2. Java is the technology related to hardware based programming, basically a technology built into the pc itself once the Java library is downloaded, whereas a Twitter api is a software based technology, nah computer with access to the internet can use it when online.

  3. Tesla autopilot button. Once within a certain, predetermined set of parameters, once I press the button the car will be able to drive itself to the destination, a very simple abstract application to a very complex problem

Answers For What is an API Assignment.

  1. An Application Programming Interface is a term used to describe the way a program interacts with separate software components, programs, and resources.

  2. Twitter is a web-based JSON API that allows programmers to interact with Twitter data. While the Java API is a library of software components that can implement common tasks that generally create increased productivity by allowing programmers to not have to write common tasks from scratch.

  3. Driving is an example of abstraction from daily life. When one would like to travel they only need directions to a location, gas, a driver’s license, and a key to the car. The driver does not need to know how combustible engines work, we don’t need to know the underlying mechanics of a specific automobile, or understand how the network of roads intersect in order to drive and get to a destination.

  1. an API is a term used to describe how programs interact with each other and contains all the possible interaction with such program/software component.

  2. the Java API comes with the Java development kit as a sort of manual and probably can be used without having an internet connection. the Twitter API is web-based and lets you interact with Twitter data by sending HTTP requests just like a browser.

  3. an API is an abstraction in the sense of it “dumbing down” actions and their outcome. using an API gives you the outcome of a set of happenings without having to know those in-between happenings. like the AMZN dash button. you push the button and soon after you get toilet paper (or whatever you order) delivered at your door, in between many things happen but you don’t (have to) know all that. another example would be that by blinking your eyes every once in a while they won’t begin to hurt. just close your eyes very shortly every so often and you’ll be good, you don’t need to know about the inside of your eyelids putting a small blanket of moisture over your eyeballs which is what keeps them from hurting. assuming blinking is something you don consciously.

  1. What is an API
    Application Programming Interface. It uses the concept of abstraction in computer science to basically reduce the workload of a developer by using a set of preprogrammed actions for a specific work which can be used in by multiple users that don’t want to repeat these lines of code again.

  2. In the article the author compares Java API to Twitter API. What is the main difference between these two APIs?
    Java API is on your computer whereas Twitter API can only be accessed via internet as it is web based API.

I am a tour guide with a tour company. A tourist comes to us and orders a private tour guide. The tourist gets our guide API which has done all the work of training and licensing the guide, making sure there is a proper website that promoted our service, the invoice is generated for the tourist, coordination of where and when the tour will start.

    In my daily life apple pay has saved my life many times and this process has become so simple as to type my password into my phone and hold my phone to the card reader to see the transaction has been approved. This is the frontend process but the backend process has to communicate the transaction cost and verify that my bank balance has the funds necessary to cover the transaction.

  1. What is an API?
    API means Application Programming Interface, it is a set of pre-determined rules or codes that help you in your functionality of your programming.

  2. In the article the author compares Java API to Twitter API. What is the main difference between these two APIs?
    Java API has a list of commands that you can use in your programming. Instead of developing from ground zero, you don’t have to do that anymore with Java script.

As for Twitter API, it is web-based programming you can use to extract data from the Twitter dataase.

  1. An API can be defined as what a software component can do and how it can do the things it can do. APIs are all of the parts of a software component what make it what it is.

  2. The Java API is a library of software components which are designed to make life more easier for programmers since they don’t have to start from scratch. Essentially, Java’s API makes it easier to program simple components such as lists.

Twitter API is web-based and allows developers to interact with Twitter data. For example, tweets, a basic element in Twitter is broken down in the API so that we know what we can do with them and how we can perform such actions.

  1. An abstraction in my life would be the concept of oyster cards that you tap on the barrier when exiting a train station. The barriers can read how much money you have on your oysters and make a decision to open or remain shut if. The barriers open if you have enough money on your oyster and stay shut if you don’t have enough money.

How I see it is that I tap a card on a barrier and the doors open. However, the process is much more complex. The oyster card reader has to read my balance, and then send this information to the motors of the barrier door via an electronic signal, only if my balance is above the minimum amount required for travel (I’m probably waffling here but ik what I’m saying :joy:)

  1. API stands for Application Programming Interface. APIs are a set of functions a procedures that allows for the creation of apps that can access data and features of other apps, operating systems and services.

  2. Java APIs include classes, interfaces and user interfaces in the JDK. They enable developers to integrate various apps and websites and offer real time information. And Twitter API is a web based JSON API that lets you read and write Twitter data.

  3. Every morning when I make coffee it would be an abstraction process. I would insert my coffee pod into the coffee machine and after 1 minute as the machine would do it’s thing I would have a fresh cup of coffee ready to be enjoyed.
