**APIs profiled:** 9

Java is a high-level, class-based, object-oriented programming language developed by Sun Microsystems and now stewarded by Oracle. The Java Standard Edition (SE) platform provides a comprehensive set of APIs and class libraries for building cross-platform applications. Key APIs include Collections, Concurrency, I/O, NIO, Networking, JDBC, Reflection, and Streams. Java is the foundation for the Jakarta EE enterprise platform and is supported by an extensive ecosystem of open source projects, frameworks, and runtimes.
