Introduction to the OOP Concepts in Java

OOPs, or object-oriented programming, implies to the languages that uses objects in programming. It works on the principles of inheritance, abstraction, polymorphism, and encapsulation. OOPs is the fundamental concept of top programming languages like Java, Python, C++, Ruby, etc. Thus, it is imperative to learn OOPs to build a programming career, especially in Java. OOP concepts are the core of Java coding. It enables Java developers to improve code reusability and readability by efficiently defining Java programs. You can develop a deep understanding of Java OOP concepts by joining a Java coding bootcamp. If you also want to learn about OOPs concepts, let’s guide you through them.

Object-Oriented Programming in Java

Today, Java is the most sought-after coding skill, and everything in Java is based on an instance of a class known as an object. It contains an address and occupies some space in the memory. All objects in Java coding can communicate without knowing the details of each other’s code or data. The central objective of OOP is to combine the data and the functions that run on them so that no other part of a code can access this data except that function.

Four Basics Principles of OOPS in Java Coding

1. Encapsulation: It is one of the key concepts in OOPs that binds together code and data into one unit and keeps them safe from any external misuse and interference. In Encapsulation, only the current class’s methods can access data as it is hidden from the other classes, which is called data hiding. Encapsulation acts as a protective shield that prevents outsiders from accessing data and code, thus keeps that data and code safe within a class itself. It is attained by declaring variables as private and enabling public setter and getter methods to view and modify the variable values. In this OOPS concept, a class’s fields are made write-only or read-only which improves code reusability. Encapsulation allows you to reuse objects like code variables or components without providing open access to the data system-wide.

2. Abstraction: Abstraction is a process where you only display an object’s essential information and hide unnecessary details from the users. It can be achieved in two ways interface and abstract class. You can obtain partial abstraction with an abstract class, while total abstraction is only possible through interfaces. It helps to reduce data complexity and avoid code repetition. Abstraction provides flexibility to developers to change the implementation of an abstract behavior.

3. Inheritance: This OOP concept allows you to create a child class that can inherit the methods and fields of a parent class. The child class can override the methods and values of a parent class, but it is not necessary. It can also add new data and functionality to its parent. Parent classes are also known as base classes or superclasses, while child classes are called derived classes or subclasses. Java deploys the extends keyword to implement inheritance in code and to create a child class. Inheritance implements the Don’t Repeat Yourself (DRY) coding principle and improves code reusability.

4. Polymorphism: Polymorphism allows you to differentiate between entities with the same name. It lets developers perform an action in multiple ways. A single variable in Polymorphism can be used to store different data types. There are two types of Polymorphism in Object-Oriented Programming, as below:

Static polymorphism: It is a polymorphism resolved during the compile time, for example, method overloading.

Dynamic polymorphism: A polymorphism resolved during run time is called dynamic polymorphism, for example, method overriding.

Having a solid foundation in OOP concepts in Java can help you write reusable, cleaner, and modular code. It also enables you to comprehend the codebases of your prospective company. If you want to learn the real-world implementation of OOP concepts, take the best Java Training in Denver.

Benefits of Learning OOP Concepts

OOPs is the core development approaches of Java that offers several benefits to developers, such as:

Simplifies code maintenance: OOPS streamlines the process of maintaining existing codes as new objects in Java coding. Thus, it saves time as one can incorporate new changes to the existing code.

Allows code reusability: Another benefit of learning OOPS is it facilitates Java developers to write code once and use it multiple times.

Higher Security: Abstraction and data hiding limit the code exposure and allow users to only access essential data which maintains security.

Debugging and troubleshooting get easy: Knowing your way around OOP concepts allows you to troubleshoot any problem with ease. Encapsulation removes the possibility of code duplicity as objects are self-constrained.

A Beginner's Guide to How to Code in Java

Java is the most popular coding language in the world. It is an easy, readable, and versatile language used for a broad spectrum of applications. Java is the top choice to learn for freshers and experienced developers which is why it has thousands of searches each day on how to code in Java. If you also want to kickstart your Java programming career, let’s guide you. This blog covers everything from why you should learn Java to the tools you need to know and how a Java bootcamp can help you master this language.

Use of Java Programming

Java runs on various devices and applications such as laptops, TV sets, embedded systems, mobiles, computers, etc. Java plays a dominant role in Android app development. Almost all Android operating systems and applications are built on Java. Besides, Java is a widely used language for building robust backend web apps for large websites. Reportedly, around 80% of the world’s largest websites deploy backend web applications built on Java. It means that knowing your way around Java coding can enlarge your job prospects. Thus, joining a coding bootcamp for Java training seems to be a safe bet for your career. 

Why do Developers prefer Java over other Languages?

Java can run on any operating system or platform through Java Virtual Machine (JVM). Being platform-independent Java-based programs only have to be written once.

Java is extremely scalable, so a Java application can deal with many users by changing the hardware configuration instead of the application itself. It enables developers to keep the code running smoothly without any bugs.

Java has a simple, English-like syntax, making it the best language to start as a beginner. Moreover, Java offers a variety of pre-built development and testing tools that further streamlines developing, designing, deploying, testing, and maintaining high-end applications.

Apart from the ease of using Java, it offers many other benefits like remunerative salaries, long-term stability, different career options to professionals competent in Java programming. Thus, getting upskilled in the best Java bootcamp can be a lucrative career decision.

Tools that every Java Developer should know:

Many online tutorials and courses may enable you to write Java codes directly into the code editor, but that doesn’t work in the real world. It is indispensable for you to learn the right set of Java tools. Let’s understand the two most important tools to get started in Java:

JDK (Java Development Kit): It is a program that allows you to write codes in Java from the comfort of your desktop. JDK consists of many tools that facilitate creating, optimizing, and running the Java code.  

The Eclipse IDE: It is another popular tool used in conjunction with the Java Development Kit. The Eclipse IDE simplifies the basic tasks such as code compilation, debugging, organizing code files, and allows you to concentrate better on writing and testing processes.

Java Event: Types and How They Work?

Java programming is the backbone of several websites, mobile applications, servers, and desktop GUI. Due to its platform independence, versatility, robustness, security features, it has been a core language for multiple startups and top tech organizations.

Many beginners like to start their coding career with Java as Java coding is simple. The simple English-like syntax makes it easy for the programmers to learn it with training and practice. Considering this, many institutions offer short-term training programs for Java. Most Java training in San Francisco is 3-6 months long and can teach the learners basic and advanced programming skills from scratch. The training is aimed to help tech enthusiasts build a solid coding foundation.

You'll learn several concepts as part of your Java training. One such popular concept is an event related to Java's event handling mechanism in the Swing GUI library.

Java Swing is a lightweight GUI (graphical user interface) widget toolkit, offering a rich set of widgets and several packages useful for developing desktop Java applications.

Java Swing Event Handling

Swing GUI applications are event-driven, meaning they react to numerous events generated throughout their lives. These events result from user interaction with the application or other means.

This article will help the learners understand what an event is, its types, and how event handling works.

What is an Event?

An event is a change in the state of an Object. It is triggered by any change in the Graphical User Interface (GUI. Whenever a user clicks on a button, moves the cursor, clicks on the combo box, types characters in the field, scrolls page, closes the window, etc., a relevant object event is created.

In simple words, an event is a signal that the operating system gives to the program whenever a user does something, or a change occurs in an instant in time. It indicates the user's interaction with the GUI components.

Let's understand this phenomenon with an example. Let's say you have a JButton, a push-button; so, whenever a user clicks on this button, an event will be triggered and created.

The created event will then be sent to the relevant event listener. For an event like this, ActionListener is the relevant listener, which has the implemented code defining the action to be taken if such an event occurs.

The ActionListener interface is a part of the Java.awt.event package and has only one method: actionPerformed (). This method is automatically invoked when you click on the JButton.

It is imperative to note that the component should be paired with the event listener. Otherwise, no action will initiate from the trigger caused by the change in the GUI.

An event is generally classified into two categories

Foreground Events – These events occur when the user directly interacts with the GUI components by clicking on a button, moving the cursor, typing a character through a keyboard, scrolling the page, clicking on an item from a list, etc. They are generated by direct user interaction and triggered when any related change happens.

Background Events – Unlike the foreground events, these events don't require the user's interaction. They generally happen due to interruption in the operating system, hardware/software failure, timer expiration, completion of the operation, etc. All these events have less to do with user interaction and happen in the background.

Event Handling

Event handling is an instrument by which the events can be controlled. It determines what action to take after an event takes place. Java coding follows the Delegation Event model to handle the events.

The delegation Event Model comprises two key elements: source and listener. Event Handling requires the source to be registered with the listener.

Source: Events occur when you make changes in the GUI, and sources are how you make those changes. Examples of sources are the push button, checkbox, menu items, scrollbar, drop-down list, text components, etc.

Listener: An event listener is responsible for handling the event. Each source has a specific event listener that manages the events triggered by their use.

Types of Events

There are various types of events and listeners in Java. Each event is associated with a matching listener. Let's look at some common events types in Java and their corresponding listeners.

ActionEvent: It occurs when a graphical element is clicked, like a button or an element in a list. ActionListener is the event listener for the ActionEvent.

KeyEvent: This Event is triggered when the user presses, types, or releases a key. The event listener related to it is, KeyListener.

ContainerEvent: It is an event that occurs in the GUI's container. It is triggered when a user makes changes to the interface by adding or removing an object. ContainerListener is the event listener for it.

MouseEvent: This Event occurs after clicking or pressing the mouse. MouseListener is the related listener for it.

WindowEvent: It is an event relating to changes happening in the window. For example, when a window closes, it is activated or deactivated. WindowListener is the Related listener for this event.

Remember that multiple event sources and listeners can interact with one another at a single point in time. It happens because a single listener can register multiple events of the same type.

One event listener can handle a set of components performing a similar action. Similarly, a single event can be related to multiple listeners. However, it's a rare occurrence. How Do Events Work? Let's understand how an event works through a common type of Event, ActionEvent. ActionEvents are generated when a user clicks an item in the list or a button.

As a result of the user interaction, an ActionEvent object matching the corresponding event is created. The object includes the event source information and the action performed by the user. This information is passed to the related ActionListener object's method:

void action Performed (ActionEvent e)

After the method is executed, an appropriate GUI response is returned, which could be to open or close a dialogue box, give a digital signature, download a file, or any action available to the users in the interface. ConclusionThis article discussed the event, its types, and event handling in detail. Similar to this concept, there are several concepts in Java. If you want to familiarize yourself with the advanced Java concepts through hands-on training, a Java coding bootcamp like SynergisticIT can help.
