Introduction to Java | Java Tutorial | Java language

Java is a powerful general-purpose programming language. It is used to create mobile and desktop applications, embedded systems, and other applications. Java is one of the most widely used programming languages.

Java was one of the most popular programming languages. Java is an object-oriented programming language.
It is not considered pure object-oriented, however, because it supports primitive data types (like int, char, etc). JAVA was created in 1991 by James Gosling at Sun Microsystems Inc, which was later acquired by Oracle Corporation. It is a straightforward programming language. Java simplifies the process of writing, compiling, and debugging programs. It helps in the formation of reusable code and modular programs.

  • Object-Oriented–> Java is an object-oriented programming language. It is not considered pure object-oriented, however, because it supports primitive data types (like int, char, etc).
  • Platform Independent–> Unlike many other programming languages, including C and C++, when Java is compiled, it is compiled into platform-independent byte code rather than platform-specific machine code. This byte code is distributed over the internet and interpreted by the Virtual Machine (JVM) on the platform on which it is run.
  • Simple–> Java is intended to be simple to learn. It is simple to master if you understand the fundamental concepts of OOP Java.
  • Safety –> Java’s secure feature enables the creation of virus-free and tamper-proof systems. Public-key encryption is used in authentication systems.
  • Architecture-neutral–>With the inclusion of the Java runtime system, the Java compiler generates an architecture-neutral object file format, which makes the compiled code executable on a wide range of processors.
  • Portable–>Java is portable because it is architecture-neutral and has no implementation-dependent features of the standard. The Java compiler is developed in ANSI C, which is a POSIX subset, with a clean portability border.

Java Application Types

Java programming can be used to create four different types of applications–>

Standalone Application Web-based Application Enterprise Application Mobile Application
Desktop applications and window-based applications are also known as stand-alone applications. These are traditional software that must be installed on each machine. Examples of standalone applications include media players, antivirus software, and so on. In Java, AWT and Swing are used to create standalone applications. A web application is an application that runs on the server and generates a dynamic page. Currently, technologies such as Servlet, JSP, Struts, Spring, Hibernate, JSF, and others are used to develop Java web applications. An enterprise application is a type of distributed application, such as a banking application. It offers benefits such as high-level security, load balancing, and clustering. EJB is a Java framework for developing enterprise applications. A mobile application is an application designed for mobile devices. Android and Java ME are currently used to develop mobile applications.

Java Platforms

Java Standard EditionJava Enterprise EditionJava Micro EditionJavaFX
It is a programming platform based on Java. Java programming APIs such as java.lang, java.io, java.net, java.util, java.math, java.sql, and others are included. It covers fundamental concepts such as OOPs, String, Regex, Exception, Inner classes, Multithreading, I/O Stream, Networking, AWT, Swing, Reflection, Collection, and so on.It is an enterprise platform primarily used for the development of web and enterprise applications. It is based on the Java SE platform. It covers topics such as Servlet, JSP, Web Services, EJB, JPA, and others.It is a micro platform devoted to mobile applications.It is used to create high-quality internet applications. It makes use of a  lightweight user interface API.

Why Should You Use Java?

  • Java runs on a variety of platforms (Windows, Mac, Linux, Raspberry Pi, etc.)
  • It is one of the most widely used programming languages in the world. It is simple to learn and use.
  • It is open-source and free to use.
  • It is safe, quick, and powerful.
  • It has a lot of community support (tens of millions of developers)
  • Java is an object-oriented programming language that gives programmes a clear structure and allows code to be reused, lowering development costs.

History

Java’s history is fascinating. It is a programming language that was developed in 1991. The Java language was created in 1991 by James Gosling, Mike Sheridan, and Patrick Naughton, a team of Sun engineers are known as the Green team. Sun Microsystems released Java 1.0, the first public implementation, in 1996. It offers free run-times on popular platforms. Arthur Van Hoff rewrote the Java1.0 compiler in Java to strictly adhere to its specifications. With the introduction of Java 2, new versions included multiple configurations for various platforms.

Sun Microsystems approached the ISO standards body in 1997 and later formalized Java, but it quickly dropped out of the process. Sun used to make the majority of its Java implementations available for free, despite the fact that they were proprietary software. Sun made money from Java by selling licenses for specialized products like the Java Enterprise System.

Sun released a large portion of its Java virtual machine as free, open-source software on November 13, 2006. Sun completed the process on May 8, 2007, by making all of its JVM core code available under open-source distribution terms.
