The Java 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.
getRoot() method of java.nio.file.Path used to return path object of the root component of this path object or null if this path does not have a root component.
Syntax:
Path getRoot()
Parameters: This method accepts nothing.
Return value: This method returns a path representing the root component of this path, or null.
Below programs illustrate getRoot() method:
Program 1:
// Java program to demonstrate// java.nio.file.Path.getRoot() method  import java.io.IOException;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:\\eclipse");          // call getRoot() to get root path        Path root = path.getRoot();          // print Root Path        System.out.println("Root Path: "                           + root);    }} |
Program 2:
// Java program to demonstrate// java.nio.file.Path.getRoot() method  import java.io.IOException;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("C:/Resume.pdf");          // call getRoot() to get root path        Path root = path.getRoot();          // print RootPath        System.out.println("Root Path: "                           + root);    }} |
