What our customers are saying


At a Glance: Java Development

Java is a free, open-source, object-oriented programming language, plus a high-powered development platform used to build tiered applications and fast-running server applications. Because Java is a portable, “write once, run anywhere” language, Java developers are able to write code that is compatible everywhere. With components including libraries, frameworks (like Hibernate), Java APIs, the Java Runtime Environment, Java Plugins, and Java’s Virtual Machine (JVM), it’s fast and scalable, making it great for enterprise-level applications.

A highly skilled Java developer on Upwork can help build and maintain a high-traffic server-side application, or develop your Android mobile application with the Gradle build tool, an application programming software, which is based on the Java programming language. Core Java refers to a subset of developer skills within the platform—basic tools and knowledge that ensure the professional you’re engaging knows their way around the complex Java platform. Java developers handle server-side security and database architecture, using Java project management tools like Apache’s Maven. Java developers also handle software debugging, quality control, testing, and much more.
