Java Programming Language

Java is widely known as a general-purpose, object-oriented, class-based programming language invented for having more secondary implementation provinces. Java is a popular computing platform that is used for the development of applications. This programming language is fast, reliable, and secure. Thus, it is used widely for the development of Java applications for cell phones, data centers, laptops, scientific supercomputers, game consoles, etc.

What is Java Platform?

Java Platform is a compilation of programs that support programmers to build and run applications based on Java efficiently. It comprises a complete set of libraries, a compiler, an execution engine, etc. It is a collection of computer programs and stipulations. James Gosling was the founder of the Java platform at Sun Microsystems. Later, it was obtained by the Oracle Corporation.

This general-purpose programming language is designed to provide all the ease to the application developers. Java works on the WORA (write once, run anywhere) concept, which means that selected Java code can operate across different platforms supporting Java. There is no need for recompilation.

The majority of Java applications are often compiled to bytecode. These applications can operate on different Java virtual machines (JVM) despite the underlying computer structure. The Java syntax is very similar to C++ and C but has minimum low-level abilities than each of them. The Java runtime implements productive capabilities. This includes representation and runtime code alteration. These capabilities are not typically available in conventional compiled programming languages. According to GitHub, Java was one of the most prevalent programming languages in 2019. This statement was released on the basis of client-server web applications. It was reported by 9 Million developers.

The Fundamental Principles of Java Programming Language

There were five fundamental principles in the development of the Java programming language:

  • Java should be easy, object-oriented, and forward.
  • Java should be reliable and robust.
  • Java should be manageable and architecture-neutral.
  • Java should run with seamless performance.
  • Java should be interpreted, productive, and threaded.

History of Java Programming Language

As mentioned earlier, Java was formerly originated by James Gosling at Sun Microsystems. Since then it has been obtained by Oracle. Later in 1995, this was released as a core element, the Java platform of Sun Microsystems. The primary and associate implementation Java compilers, class libraries, virtual machines, were formerly released by Sun Microsystem. This was released under established licenses.

In May 2007, Sun relicensed the majority of its Java technologies under the General Public License (GNU) in agreement with the terms of the Java Community Process. The most advanced version of Java is Java 15. This was launched in September 2020. The Java 11 is a currently established long-term support (LTS) variant. This variant was launched on 25 September 2018. Oracle launched for the provision Java 8 LTS; this was the final zero-cost public update that came out in January 2019 for practical use.

Top Reasons to Use Java Programming Language

  • Java runs on various platforms which include Mac, Windows, Raspberry Pi, Linux, etc.
  • This is one of the most prominent programming languages worldwide.
  • Java is simple to learn and easy to use.
  • Java is a free and open-source platform.
  • Java is a reliable, secure, agile, and robust platform.
  • Java comes with vast community support. There are around 10 million developers working behind it.
  • This object-oriented programming language provides a definite structure to programs and enables programmers to reuse the code, reducing the cost of development.
  • Java is very similar to C++ and C#. This makes it easier for developers to shift to Java or vice versa.

What are the Purposes of Java Programming Language?

Here are some important uses of Java programming language:

  • It is utilized for the development of Android Applications.
  • Java can also be used for the development of Enterprise Software
  • Java also supports Mobile Applications Development.
  • The Scientific Computing Applications are also developed on Java.
  • Java also Supports Big Data Analytics.
  • Utilized for Server-Side Technologies such as JBoss, Apache, GlassFish, etc.

Elements of Java Programming Language

The Java Programmers always write a program in a human-readable programming language. This is known as Source Code. Hence, the computing systems or chips never learn about the source code composed in different programming languages.

These computing systems or chips only understand a single thing and that is known as code or computer language. These computer codes work at the CPU level. This means there must be distinctive machine codes for different paradigms of CPU.

Java Development Kit (JDK)

Java Development kit can be defined as a software development environment that is utilized for creating Java applications and applets. JDK is the abbreviated form of the Java Development Kit. Java programmers can utilize it on Solaris, macOS, Windows, Android, and Linux. JDK makes it easier for them to write code and operate Java programs. It is simple to install more than a single JDK version on the very computer.

Java Virtual Machine (JVM)

Java Virtual Machine (JVM) can be defined as the engine that renders a runtime environment to manage the applications and Java Code. It changes Java bytecode into a computing language. JVM is one of the important components of the Java Run Environment (JRE). In different programming languages, the compiler generates computing code for a distinct system. However, the Java compiler generates code for a Virtual Machine. This is called the Java Virtual Machine.

Java Runtime Environment (JRE)

JRE is a portion of software that is composed to operate other software. It comprises the loader class, class libraries, and Java virtual machine. In concise terms, for efficiently running a Java program, there is a need for JRE. Those who are not a {"programmer"}, there is no need to install the Java Development Kit; with just JRE it is possible to run Java programs.
