The use of Java programming language in web development has become increasingly popular over the years. Created in the late 90s, Java is a high-level, object-oriented language designed with platform independency in mind. As a principle, Java code must be able to run on any operating system with a Java Virtual Machine (JVM) installed. This makes Java a popular choice for building web apps, as it can be utilized for both web client and web server purposes. It allows developers to write code once and run it on multiple platforms, translating to a more efficient and cost-effective web application development process. Companies specializing in back-end development services can choose from numerous Java APIs and libraries to create dynamic web pages and other complex web apps.
