Seven Basic Things In Java

Java:

Java is a high-level, generic, object-oriented, secure programming language developed in 1991 by James Gosling of Sun Microsystems, Inc. It is formally known as OAK. Sun Microsystems changed its name to Java in 1995. In 2009, Oracle acquired Sun Microsystem.

Edition Of Java:

Each version of Java has different characteristics. Java has three versions. Java Standard Editions (JSE) - used to create desktop computer software. Java Enterprise Edition (Jee): it is used to create large programs that are performed on the server and manage intensive traffic and complex transactions. Java Micro Edition (JME): It is used to provide applications for small devices such as set boxes, telephones and devices.

Types Of Java Applications:

Standalone Applications: 

Standalone Java applications use GUI components such as AWT, Swing, and JavaFX. These components include buttons, lists, menus, scrollbars, etc. They are also known as office aliens. Enterprise software is distributed software in nature called enterprise application. 

Web Applications: 

Applications running on a server are called Web applications. We use JSP, Servlet, Spring and Hibernate technologies to build web applications. Mobile Applications: Java ME is a cross-platform platform for developing mobile applications that run on smartphones. Java is the Android application development platform.

Java Platform:

The Java platform is a collection of programs. It helps you develop and run programs written in the Java programming language. Java is a platform independent language. To improve your knowledge, get through Java Training in Chennai.

Features Of Java:

Simplicity: Java is a simple language because its syntax is simple, clean and easy to understand. Complex and ambiguous concepts in C ++ are removed or reintegrated in Java. 

Object Oriented: 

In Java, everything is in the form of an object, that is, it contains some data and behavior. The program must have at least one class and one object

Strong: 

Java strives to check for errors at runtime and at compile time. It uses a powerful memory management system called Garbage Collector Exception and is powerful with the garbage collection feature.

Safe: 

Java is a safe programming language because there are no explicit pointers and no programs running in virtual machines. Java has a security manager that defines access to Java classes.

Portable: 

Java bytecode is portable to all platforms. There are no implementation-dependent features. Everything about the storage is predetermined, for example the size of the raw data types.

Decentralised: 

Java also has networking capabilities. It is designed for the distributed environment of the Internet as it supports the TCP/IP protocol. It can be played online. EJB and RMI are used to build distributed systems. 

Multithreading: 

Java also supports multithreading. This means running more than one business at a time.

OOPS ( Object Oriented Programming System ):

Object-oriented programming is a way of solving a complex problem by breaking it down into small sub-problems. It's easy to develop a program with an object. In OOP, we build programs in a structured way using classes and objects.

Class:

A class is a model, Blueprint, or prototype that defines the data members and methods of an object. An object is an instance of a class. You can define a class using the class keyword. 

Objects:

An object is a real-world entity that can be uniquely identified. For example, a table or a circle can be considered as objects. Objects have their own behavior, identity, and state. A data field with its current value represents the state (also called a property or attribute) of an object.

Abstraction: 

Abstraction is a method of hiding irrelevant information from users. For example, a driver only knows how to drive a car. A class can be abstracted using the abstract keyword. 

Encapsulation: 

Encapsulation is the process of associating data and functions into a single unit. Categories are an example of encapsulation. In Java, a Java Bean is a fully encapsulated class.

Inheritance: 

Inheritance is the system in which a class inherits all the characteristics of another class. We can achieve inheritance using keyword extension. The code is easy to reuse.

Conclusion:

Java provides a way to write most programs in a type-safe language. However, for Java to be widely useful, it must have more expressive power than it currently has. This white paper covers an area where more strength is needed. To be a successful python programming language you can get a Python Training in Chennai.
