Enterprise Use
Java has been the dominant enterprise backend language for decades. It powers large-scale distributed systems, financial applications, e-commerce platforms, and enterprise middleware. Major enterprise products built on Java include Atlassian Jira, Confluence, ServiceNow, and Cisco Webex. The Spring Framework makes Java the default choice for enterprise microservices and REST APIs. Android application development also relies on Java.
