Once we have reference to a file system object, we can obtain a Path object using any one of several methods: ff getPath: This uses a system-dependent path to obtain a Path object. The Path object is used to locate and access the file. ff getPathMatcher: This creates a PathMatcher. It performs various matching type operations on a file and is covered in the Getting filesystem information recipe in Chapter 5. ff getRootDirectories: This is used to obtain a list of root directories. This method is illustrated in the Getting filesystem information recipe in Chapter 5.

When a Path object is created, it is not necessary that the actual path exists. For example, the Path may be created to create a new filesystem element. The Converting between path types recipe looks at methods used to convert between these different types of paths. Paths are system-dependent. That is, a path on one system such as UNIX is different from one found on a Windows system. Comparing two paths found on the same platform may or may not be the same. This is examined in the Determining whether two paths are equivalent recipe.

Here, we will illustrate this approach by creating three classes: ff One class that contains the main method ff Two classes that implement the AutoCloseable interface 1. Create two classes called FirstAutoCloseableResource and SecondAutoCloseableResource. println("SecondAutoCloseableResource manipulateResource method executed"); } } 2. Next, add the following code to a main method. println(throwable); } } 3. close(FirstAutoCloseableResourc ... UnsupportedOperationException: A problem has occurred in FirstAutoCloseableResource How it works...
