Java Concept and Features
Java Course Fees in Hyderabad
The fundamental principles that are fundamental to Java is it’s object-oriented programming (OOPs) characteristics. OOP helps simplify development of applications and software and maintenance through the use of concepts, such as:
1.Object: An object is an element or entity with a status and behaviour. For instance the dog could be considered to be an object that has the colour, breed, and even a name. It can also be identified by its behaviour, such as eating and barking.
2.Class The term “class” refers to a set of many objects. It’s a blueprint that could be utilized to build any number of objects you’d like. The classes are utilized to arrange codeine the same way that vegetables, fruits and medical products are separated into various sections of the supermarket.
3.Constructor Constructor could appear as a method, but it’s not a method. The name of the constructor is the identical to the class name but it does not provide any value.
4.Inheritance Inheritance is the idea that a class inherits the characteristics and behaviours of its parent class.
5.Polymorphism Polymorphism refers to the method of performing the same task in various ways. Programmers can make use of the same term to refer to different terms in various situations.
6.Abstraction Abstraction in Java can be utilized to hide internal information and display only the important information.
7.Encapsulation: The process of binding or wrapping data and code together to form an entire unit (like capsules) is called Encapsulation. The Java Class is an illustration of Encapsulation.
Java is a great language with many qualities and features, such as:
- The simple syntax is extremely easy to comprehend and master
- Java language is extremely robust.
- Eliminates mistakes that can occur when using C and C++ languages. C or C++ languages
- Java is comprised of features like garbage collectors and handling of exceptions
- Since it is a portable language Java can be used on any platform
- Java is safe and is able to perform multitasking
- Java isn’t as efficient as C or C++ however, it is more efficient than other languages.
After having talked about the various features of Java Let’s look at the various parts in this Java programming language.
Components of Java
There are three primary elements in Java, the Java programming language, which includes:
- JVM – JVM is the Java Virtual Machine or JVM is an independent platform Java component that offers an environment to run Java programs. Therefore, JVM loads the code and validates the code. Then, it executes the program, and then provides an environment for running.
- JRE – It is the Java Runtime Environment or JRE creates an environment where the Java files can be executed and run. It is a program that includes JVM as well as Java class libraries, as well as Java Class Loader.
- JDK- It is the Java Development Kit also known as JDK is a subset that is a subset of JRE and is an application development environment that allows you to create Java Applets and applications. The JDK comes with an exclusive JVM as well as a number of other tools to complete the creation of the Java application.
Java OOPs Concepts
There are four main concepts of object-oriented programming (OOP), including:
- Abstraction – Abstraction is the process of displaying relevant information and hiding the details that are internal or behind the scenes. In the following example to allow a student be admitted to a college, the information required will be name address, address, parents name as well as high school marks. Particulars like favorite foods, sports or even movies aren’t relevant.
- Encapsulation – It is the same as capsules. The entire source code as well as the entire information are bundled into one single unit. All variables and methods are stored under the same classification name. only the identical class object can be used by it.
- Polymorphism- Polymorphism refers to the fact that a particular task can be accomplished in different ways. One function can be utilized to accomplish different tasks. In the case below Method Draw() is a function that can be utilized at various places to draw various shapes, such as a rectangle, triangle or a circle.
- Inheritance – If a class inherits characteristics and attributes from other classes, this is called inheritance. There’s always a superclass as well as subclass. Subclasses inherit attributes of the superclass. In the following example the animal is a superclass that includes attributes like eating() as well as sleep(). Subclasses of reptile, mammal and human have these attributes.
