What’s the Difference Between Java 11 and Java 8?

There are always a lot of little things that go into a release of Java, or any product for that matter. However, the biggest differences between Java 8 and Java 11 are:

  • The introduction of modularity in Java 11 to better support scaling down to small computing devices. Modularization also enables code to be refactored for easier maintenance, through a self-describing collection of code, data, and resources.
  • A REPL (read-eval-print-loop) tool, JShell, was added to Java 11 support  interactive programming, similar to what is available in Python.  This is very interesting for serverless-compute and one-offs in Kubernetes
  • A developer-friendly keyword “var” was added in Java 11 to help to reduce boilerplate coding. The “var” keyword only affects local variables, and the Type Inference keeps you repeating the same text over and over again
  • Due to lack of browser support for Java plugins, the Applet API has been deprecated in Java 11
  • Oracle has chosen the Eclipse Foundation as the new home for the Java Platform Enterprise Edition. As a result, those packages have moved, and this will require changes to package imports.
