  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.
