  • Running Single-File Java Source Code Without Compiling (Part 2)

    Let’s continue from part 1 of this series, by looking at JEP 330, Launch Single-File Source-Code Programs, which is one of the new features introduced in the OpenJDK 11 release. This feature allows you to execute a Java source code file directly using the java interpreter.

    The source code is compiled in memory and then executed by the interpreter, without producing a .class file on disk.

    However, this feature is limited to code that resides in a single source file. You cannot add additional source files to be compiled in the same run.

  • Running Single-File Java Source Code Without Compiling (Part 1)

    Instead of starting up the JVM, loading a class and executing the code, you can run single Java source files.

    Professionals can also make use of these tools to explore new language changes or to try out an unknown API.
