✍: FYIcenter


"javac" is the Java compiler command that allows you to compile Java source code into Java class binary file.

"javac" command is supported by the jmods\jdk.compiler.jmod module file, which is also linked into the lib\modules JImage file.

You can run the "javac" command using the lib\modules JImage file as described:
