Class FileSystemsNewFileSystemExamples

java.lang.Object
net.jrodolfo.java_evolution.java13.FileSystemsNewFileSystemExamples
public class FileSystemsNewFileSystemExamples extends Object
Demonstrates the FileSystems.newFileSystem(Path) convenience overload added in Java 13.

Before Java 13, opening an archive or other provider-backed path as a file system required more verbose overloads. That added ceremony to the common case where the path itself contained enough information.

The Java 13 overload solves that convenience problem by letting code open a supported file system directly from a Path.
