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.
getParent() method of java.nio.file.Path used to return the parent path of current path object, or null if this path does not have a parent. The parent path of this path object consists of this path’s root component and each element in the path except for the farthest from the root in the directory hierarchy. If this path has more than one element, and no root component, then this method is equivalent to evaluating the expression:
Parameters: This method accepts nothing.
Return value: This method returns a path representing the path’s parent.
Below programs illustrate getParent() method:
Parent Path: D:/workspace
Parent Path: D:
