History of Java Programming Language

Since its birth, Java has passed several milestones and has gathered many achievements. Here is a brief timeline of the programming language’s evolution:

  • 1991. Upon the release of C++ and updated C, Sun Microsystems started inventing more effective coding languages independently from individual architecture and specialized platforms. The last decade of the previous century coincides with the World Wide Web progression and searching for ways to optimize the coding process for the web environment. So, by replacing Python and Ruby, Sun Microsystems gave the background for object-oriented and class-based language.
  • 1995. James Gosling works in Sun Microsystems and fulfills the best solution for running codes in any appropriate environment with simplified backend maintenance and named it Java. Although the previous versions were known as Oak, the Java development company decided to change the language name to eliminate the risks of plagiary.
  • 1998. Java occupies the IT market, especially web users, pretty quickly and significantly improves its security and performance metrics. Encouraged by the success, Sun Microsystems releases the updated Java 2 with an optimized configuration suitable for most platforms.
  • 2006 / 2007. Java development keeps transforming into free and open code under the GNU General Public License. As such, the company loses its author rights for Java.
  • 2010. Oracle acquires Java and enhances its functional capacities with its database solutions. Thus, integration with Oracle SQL services makes Java the top language perfect for Internet programming and household equipment automatization.

All About Java Application Development Process

Here is how a generic Java application development workflow works. 

Typical Java development process

A Java development company employs the above approach, which works step-by-step as below:

  • A program when built is compiled using javac, a Java compiler, which converts the code into bytecode.
  • In the next stage, the bytecode passes to the Java Virtual Machine (JVM) that converts the bytecode into machine code.
  • However, Java works on the principle of dynamic compilation – compiling code that’s currently running.
  • JIT (Just-in-time) compilation accomplishes dynamic compilation, compiling only the requisite bytecodes, and converting them into native code.

This is a technical snapshot of how Java programs execute. In enterprise application development, the course that a Java development company will choose may vary from project to project. However, this process will always remain the foundation of any Java development project.

Let’s understand these technical components of the Java development lifecycle in more detail.

  • JDK or Java Development Kit: This software package allows the creation of platform-adaptive codes and runs them on other Java-supportive systems. These functions become realistic thanks to embedded compiler and class libraries which receive commands and generate appropriate results.
  • JVM or Java Virtual Machines: Abstractive machines with significant performance capacities, JVM can convert codes developed by other programming languages. However, its genetic function is to read Java bytecode via machine mediums. However, you could hardly finalize the programming process if you do not install JRE and configure the application implementation and maintenance actions;
  • JRE or Java Runtime Environment. Deployment technologies in JRE software run application code programmed by the other languages. Its libraries and upgraded compiler efficiently process the client inquiries and verify the bytecodes. However, to increase the performance capacities, you should install both JVM and JRE to compile the Java-related programs with minimum omissions.

The above concepts practice the methodologies appropriate for any language. Java easily synchronizes with Waterfall, Kanban, or Agile techniques. Moreover, you may adjust automation verification processing to test the quality and correctness of the generated codes.

Java Development Lifecycle and Methodology

An application development lifecycle goes beyond the technological considerations of the project. Here is how the Java development lifecycle works:
