Path getNameCount() 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.

getNameCount() method of java.nio.file.Path used to return the number of name elements in the path. If this path only represents a root component then method will return 1.

Syntax:



int getNameCount()

Parameters: This method accepts nothing.

Return value: This method returns the number of elements in the path, or 1 if this path only represents a root component.
