What is Java Development Kit (JDK) in Java?

When building Java-based software applications, JDK can help to fast-track the development process and simplify the project. Along with the JVM (Java Virtual Machine) and the JRE (Java Runtime Environment), JDK is among the core technologies used in Java programming.

A proper understanding of JDK can help you make vital decisions about the software building project. This blog explores JDK in detail.

What is JDK?

The term JDK stands for Java Development Kit and is basically a collection of software development tools and supporting libraries that proves handy in building Java-powered software solutions. It is used in combination with JVM and JRE.

In simple words, we can also say:

JDK(Java Development Kit) = JRE (Java Runtime Environment) + Development Tools
If you are new to Java programming, there can be significant confusion between JRE and JDK. The important point to note here is that Java developers can run programs on a machine with JRE only.

However, JDK is a must-have for building software applications.

What is the architecture of JDK?

JDK consists of JRE, which contains JVM, class libraries, and others. Let’s explore these in detail.

JVM (Java Virtual Machine)

Java Virtual Machine (JVM) basically provides a run-time environment for the Java source code to run. JVM is the reason why Java developers can leverage “Write once and run anywhere.” This means you can run Java programs anywhere. It stays on top of the host operating system and is responsible for translating the Java source code into ByteCode (machine language) and program execution.

JRE (Java Run-time Environment)

As the name suggests, the Java Run-time Environment is the platform for executing the Java applications source code. It integrates various plugins and jar files and also offers support for libraries for running the source Java code.

How Software Maintenance and Support Services Help You Stay Ahead?

Gone are the days when testing and deployment were the last stages of the software development life cycle. With new technological advancements capturing the market, leveraging continuous software maintenance services has become imperative. 

For example, imagine having an outdated website that lacks technology trends like 2FA, SEO optimization, neglected version updates, and takes too long to load. Most website visitors will complain of poor UX and seek alternative options.

Neglecting regular maintenance leads to severe security and performance issues with the software solutions. There are various kinds of support solutions you can leverage. 

This article will help you understand why software maintenance is important. The infographic below offers insights into the predictive maintenance market.

What is Software Maintenance & Support Services?

Software maintenance can be understood as the activities performed after the application’s launch/deployment to improve its performance & security or to keep it up-to-date with the latest innovations in the technological industry. Software development services companies recognize maintenance as the last but ongoing process for optimum results. 

It helps to keep your solution relevant for the users as it enhances the software according to the changing business requirements. Regular maintenance with bug fixes, upgrades, and performance enhancements is pivotal in optimizing the solutions, eliminating outdated features, and keeping them apt for the users.
