  1. An API is an application which you program to interact with software components.

  2. Java API and Twitter API is different in relation to interactability. Java API allows for simplicity in using the programming language by hiding some complexities. It’s a library of software components (Developers kit) that implements common tasks, which simplifies, and increases productivity for the Java developer, straight out the box. Whereas Twitter API is web-based and a request must be made to get access for programmatic interaction of Twitter data.

  3. A daily life’s abstraction, my eyes open from awaking from sleep, that’s complicated in itself as per the internal processes to make that occur. I eat some breakfast and digestion takes place, the byproducts of digestion goes on to produce energy. As programmed by the developer, the specifications that’s responsible is beyond my control, all hidden under the hood. What a wonderful design!

Response:

  1. An API is an interface that helps apps and software communicate with each other to make the user experience enjoyable.
  2. The main difference between the two is that Twitter API is web-based and Java API needs the Java dev kit in order to function.
  3. An abstraction from my life…paying for everyday items using my phone, through SamsungPay/Cashapp/etc. I’m sure there are several API’s involved within to make purchases happen. The app must communicate with processing companies who check and verify that I have sufficient balance before letting the merchant know I’m good to leave with my purchase.

An API is a set of specifications that allows software components to communicate through one common interface.

The twitter API is a web-base API that is access over the internet
The java API is a literary of components that you have access to when you download the development kit.

An abstraction for me is when I uses Apple Pay at the store, I don’t have to wait for change with cash, or put in my PIN number is using debit. Another abstraction for me is having direct deposit with my job. I don’t have to physically take the check to my bank to have it deposited.

1) What is an API?

API stands for Application programming language, and it is a 2 fold “entity”:

  1. The theoretical specification describing the methods of interacting with a backend app
  2. A specific implementation of the API specification that does what the specification defines for every API method

2) In the article the author compares Java API to Twitter API. What is the main difference between these two APIs?

JAVA API is the internal development API as used within the Java Environment.
Twitter is a REST API to be used over the web by any application on any platform that can “talk” REST

3) The section in the article about abstraction is important, try to understand it and write down an abstraction from your daily life.

An abstraction, is a description what is done, without necessarily specifying how and why.
From my life:

WakeUpEarly
Hydrate
GetEnergized
InvestInMyself
Feed
doWork
etc

** What is an API?**

Is the piece of code which allow component to interact with each other in different way (share information,data,etc)
2) In the article the author compares Java API to Twitter API. What is the main difference between these two APIs?

The Twitter API is a web-based JSON API that allows developers to programmatically interact with Twitter data. Unlike the Java API, which is included in the Java Development Kit, the Twitter API is a web-based API.

1) What is an API? I consider it as a toolbox. In code, they are preloaded recipies or code ready to use in a software.

2) In the article the author compares Java API to Twitter API. What is the main difference between these two APIs? Java API is local library to be included in the code so it can be run without Internet. It is a general purpose set. Twitter API needs Internet to be accessed by the webApps. With Twitter, it is specific to a set of data, users tweets. The app can handle only tweets. Java can add a layer of abstraction with generic methods on the twitter dataset after the request t the server.

3) The section in the article about abstraction is important, try to understand it and write down an abstraction from your daily life. As I understand, the API is my morning routine. I don’t need to remember the sequence of my routine (API) and I will be at work on time. Another API is the employee who spread the news and digest the business information so I use it in my decisions.

  1. What is an API?
    An API is an Application Programming Interface used to exchange data between different applications and systems. You don’t have to know anything about the underlying technology of the other application, you only need to know which APIs are available and how to call them.

  2. In the article the author compares Java API to Twitter API. What is the main difference between these two APIs?
    Java API is a library of predefined components that come with the JDK (Java Development Kit) and are ready to be used.
    The Twitter API is a REST API which can be called with an HTPP request to the web server and the data is accessed in JSON format.

  3. The section in the article about abstraction is important, try to understand it and write down an abstraction from your daily life.
    An abstraction could be when you order food take-out and it arrives at your door. You don’t have to worry about how it was prepared or the process that they went through to get the ingredients, which type of cooking equipment they use or the name of the chef, all you need to do is order your favorite foods and it comes straight to your door.

  1. API is defined as a specification of possible interactions with a software component.

  2. Java API is a library of components from software, but Twitter API is a web-based JSON API.

  3. Abstraction is things that we do not need to know in order to get a result. like when we use our debit cars, the way of money floating is a huge systematic thing.

  1. What is an API?
    API allows users to interact with various programs / software components / resource.
  2. In the article the author compares Java API to Twitter API. What is the main difference between these two APIs?
    Java API allows users to use the Java data structures while Twitter API interfaces based on JSON API to interact with twitter data.
    Main difference is the Twitter API is web-based API, accessed by making requests over the internet rather than to your local installation drive within the computer / local network.
  3. The section in the article about abstraction is important, try to understand it and write down an abstraction from your daily life.
    Abstraction organises complex systems so that tasks can be handled in simple ways. An example of abstraction for the “button” for attending a meeting on client site:
    -Button pressed, leading into queries on meeting details, locations, client site representative, then automate the process
    -Smart phone calendar reminds me the night before of the day’s meeting
    -In the morning the smart phone displays weather and traffic information, simplifying my decision to know whether to carry an umbrella or not, and when to leave the house
    -ride-sharing app finds a driver in the area to drive me to the client site

  1. API is an application program interface. It is a way that software programs interact with each other, such as how servers interact with clients to return data and the sets of rules these adhere to
  2. Twitter API is web-based and any interactions between programs come from services that twitter hosts, whereas Java API is a library of software components included in the Java development kit
  3. I have a coffee station in my home where my grinder, machine, scale, beans, and tools are stored so that I can access them all easily and efficiently.

  1. An API is a program that simplifies the communication between the backend and frontend.
  2. The Java API connects to the Java Platform installed in the local computer and helps in building the application. Twitter API is REST API sending JSON messages back and forth with the server via the internet.
  3. An abstraction layer contains multiple activities and makes them available as a package.
    For example, leaving products in the freezer to get cold. In this case, the fridge activates a temperature sensor to keep at a set temperature, and if needed it runs a motor to compress and circulate gas for heat dissipation. All the activities of the fridge are abstracted from the user.

1) What is an API?

an API is like a bridge between two different pieces of software/programs/code, it can be a bridge between a FE application and a BE server app, but there are other examples inside the same article. The idea of the API is that developers could abstract from all the complexity there is to connecting their own developed FE application (for example) to an existing BE server app, used already for many others FE apps

2) In the article the author compares Java API to Twitter API. What is the main difference between these two APIs?
The Twitter API is Json based using HTTP (it is web based), while the Java API makes use of libraries to deliver the info from the server.

3) The section in the article about abstraction is important, try to understand it and write down an abstraction from your daily life.

Using Uber Eats or any other Food app might be an everyday example of an API. I can just repeat some order which I already made last time, and I dont have to go through all the process of choosing the meals individually, insert my card data, my address and so on

1.Set of predefined rules which allow 2 or more applications to talk to each other, by abstracting the complexity of individual systems.

  1. Java API is set of rules which comes out of the box with Java SDK which can be used to build custom applications using the Java libraries, classes, lists etc. Twitter API lets you or your application read and write Twitter data. These API calls can either be a GET or POST. API calls generally done over the web using HTTP or HTTPS.
