What is Java?

Java is a widely used object-oriented programming language and software platform that runs on billions of devices, including notebook computers, mobile devices, gaming consoles, medical devices and many others. The rules and syntax of Java are based on the C and C++ languages.

One major advantage of developing software with Java is its portability. Once you have written code for a Java program on a notebook computer, it is very easy to move the code to a mobile device. When the language was invented in 1991 by James Gosling of Sun Microsystems (later acquired by Oracle), the primary goal was to be able to “write once, run anywhere.”

It’s also important to understand that Java is much different from JavaScript. Javascript does not need to be compiled, while Java code does need to be compiled. Also, Javascript only runs on web browsers while Java can be run anywhere.


When is Java a good choice for a software application?

Java is a versatile language and can be a good choice for a variety of software applications. Here are scenarios where Java shines:

  • Cross-Platform Development: Java’s “Write Once, Run Anywhere” philosophy means that Java applications can be developed on one platform and run on virtually any other platform, as long as there’s a Java Virtual Machine (JVM) available.
  • Enterprise Applications: Java EE (Java Platform, Enterprise Edition) provides a robust, scalable platform for developing large-scale enterprise applications. Many big corporations rely on Java for their backend systems, CRM, ERP, and other enterprise software.
  • Web Applications: With frameworks like Spring, Hibernate, and JavaServer Faces (JSF), Java is a strong contender for building dynamic web applications. Servlets and JSPs in Java allow for creating web-based applications with ease.
  • Mobile Applications: Android, the world’s most popular mobile operating system, is primarily based on Java. If you’re aiming to develop Android apps, then Java is the language to know.
  • Embedded Systems: Java ME (Java Platform, Micro Edition) offers solutions for embedded systems and resource-constrained devices.
  • Big Data Technologies: Java plays a significant role in big data technologies. Hadoop, the widely-used big data processing framework, is written in Java.
  • High-Performance Systems: Java’s performance has improved considerably over the years. With the Just-In-Time (JIT) compiler and various performance enhancements in the JVM, Java can be used for high-performance applications.
  • Cloud-Based Applications: Java offers robust support for cloud-based applications, making it a good choice for cloud solutions. Java EE, Spring Cloud, and other frameworks offer tools and libraries specifically for this purpose.
  • Distributed Systems: Java has built-in support for distributed computing. Java RMI (Remote Method Invocation) and technologies like EJB (Enterprise JavaBeans) make it easier to create distributed applications.
  • IoT Applications: With the rise of the Internet of Things (IoT), Java’s portability becomes even more valuable. Its ability to run on a multitude of devices makes it a great choice for IoT applications.
  • Learning and Academics: Java is often chosen in academic settings for teaching the fundamentals of programming and object-oriented concepts because of its robustness and relatively straightforward syntax.

However, the choice of using Java (or any language) should be based on several factors, including the specific requirements of the project, existing infrastructure, development team expertise, and long-term maintenance considerations.

What products are built using Java?

Java, being versatile and scalable, has been chosen by many companies as the language of choice for building their SaaS products. Here are some SaaS products that are built with Java or have significant components written in Java:

  • N
    Atlassian Jira

    The popular issue and project tracking application.

  • N
    Atlassian Confluence
    A collaboration tool that acts as a wiki and workspace.
  • N
    Atlassian Bitbucket
    A Git repository management solution.
  • N
    A distributed search and analytics engine. While it can be hosted on-premises, there are SaaS versions and managed services available, like Elastic Cloud.
  • N
    New Relic
    An application performance monitoring tool that uses Java in its backend.
  • N
    While Jenkins can be self-hosted, there are also cloud versions (SaaS) of this popular continuous integration/continuous deployment tool.
  • N
    Known for its marketing, sales, and service software, HubSpot uses Java in various parts of its infrastructure.
  • N
    The enterprise content management and collaboration platform use Java for several of its services.
  • N
    A leading provider of enterprise cloud applications for finance, HR, and planning has some services that utilize Java.
  • N
    While not entirely written in Java, certain backend components and services, especially those related to the search functionality, use Java.
  • N
    While it might be better classified as a PaaS (Platform as a Service) or simply a service, it’s worth noting that Netflix, one of the largest streaming services globally, heavily utilizes Java in its backend systems, especially in its microservices architecture.

These are just a selection of the many SaaS products that utilize Java. Java’s scalability, performance, and rich ecosystem of libraries and frameworks make it an attractive choice for building robust and scalable SaaS products.
