Path getFileSystem() method in Java with Examples

The Path interface was added to Java NIO in Java 7. The Path interface is located in the java.nio.file package, so the fully qualified name of the Java Path interface is java.nio.file.Path. A Java Path instance represents a path in the file system. A path can use to locate either a file or a directory.path of an entity could be of two types one is an absolute path and other is a relative path. The absolute path is the location address from the root to the entity while the relative path is the location address which is relative to some other path.

getFileSystem() method of java.nio.file.Path used to return the file system that created this Path object.

Syntax:

FileSystem getFileSystem()

Parameters: This method accepts nothing.

Return value: This method returns the file system that created this Path object.

Below programs illustrate getFileSystem() method:
Program 1:

// Java program to demonstrate
// java.nio.file.Path.getFileSystem() method

import java.io.IOException;
import java.nio.file.FileSystem;
import java.nio.file.Path;
import java.nio.file.Paths;

public class GFG {
    public static void main(String[] args)
        throws IOException
    {

        // create object of Path
        Path path
            = Paths.get("D:/workspace/AmanCV.docx");

        // call getFileSystem()
        // and get FileSystem object
        FileSystem fs = path.getFileSystem();

        // print separator of FileSystem
        System.out.println("Separator used for FileSystem: "
                           + fs.getSeparator());
    }
}

Output:

Separator used for FileSystem: /

Program 2:

// Java program to demonstrate
// java.nio.file.Path.getFileSystem() method

import java.io.IOException;
import java.nio.file.FileSystem;
import java.nio.file.Path;
import java.nio.file.Paths;

public class GFG {
    public static void main(String[] args)
        throws IOException
    {

        // create object of Path
        Path path = Paths.get("D:/Resume.pdf");

        // call getFileSystem()
        // and get FileSystem object
        FileSystem fs = path.getFileSystem();

        // print FileSystem is ReadOnly or not
        System.out.println("FileSystem is ReadOnly: "
                           + fs.isReadOnly());
    }
}

Output:

FileSystem is ReadOnly: false
