Encapsulation in Java
Java is one of the most important programming languages today. A system that is used for the development of all kinds of devices and applications. In this article we are going to see how to use the data structure in Java to improve your code.
However, if you want to become an expert in Java, the best thing you can do is to train yourself. With a specialization in this programming system, you will not only master the Java data structure, but you will also become a Java programmer. One of the most demanded professional profiles in the IT sector.
The Java data structure is the system by which data is organized in the memory of the application being programmed. There are many ways to organize data in memory.
For example, an array is a collection of memory elements in which data is stored sequentially. This type of organization is done with the help of a series of data structures. There are also other ways of organizing data in memory.
Modularity in java
Abstraction consists of selecting data from a larger set to show only the relevant details of the object. It helps to reduce complexity and programming effort. In Java, abstraction is achieved by using abstract classes and interfaces. It is one of the most important concepts of OOPs.
However, the same information once extracted can be used for a wide range of applications. For example, you can use the same data for the hospital application, the job portal application, a government database, etc. with little or no modification. Therefore, it becomes your Master Data. This is an advantage of Abstraction.
At a higher level, Abstraction is a process of hiding implementation details and showing only the functionality to the user. It only indicates important things to the user and hides the internal details, ie. While sending SMS, just type the text and send the message. Here, you do not care about the internal processing of message delivery. Abstraction can be achieved by using abstract class and abstract method in Java.
Example of abstraction in programming
Java is one of the most widely used programming languages by technology companies. A professional profile that is highly demanded, so specializing as a Java programmer will open many doors in the labor market.
One of the biggest advantages that you will find when you specialize in Java is that it is a programming language with an easy learning curve. This is, in part, because it is an object-oriented programming system. In this article we are going to tell you what this type of programming consists of and what an object in Java is. Read on!
It may seem obvious, but the basis of object-oriented programming is the object. But what is an object in Java? An object in Java is nothing more or less than the same as an object in the real world.
Objects in Java have no physical existence, you can’t touch them, but they do exist as something that contains information about itself and its state. You can interact with it and you can modify it to meet your programming needs.

Abstraction (Lat. abstractio = to take out of) is a process that involves reducing the fundamental information components of a phenomenon to retain its most relevant features in order to form categories or concepts. For example, abstracting from a willow tree the concept of a tree implies retaining only the information (characteristics, functions, etc.) of the willow that can be applied to be included within the general category of trees.
An essential question in psychology consists in trying to explain this abstraction process. For example, how people manage to form concepts from experiences with individual objects.
In education, the idea of abstracting is related to the moment when knowledge becomes part of the subject’s life (initially in a mental category) and is confirmed by explicit behavior that allows us to see that “abstraction” has been achieved.
