File Navigation and IO

There are several other classes that we would be going through to get to know
the basics of File Navigation and I/O.

  File Class
  FileReader Class
  FileWriter Class

File Class:

Java File class represents the files and directory pathnames in an abstract manner.
This class is used for creation of files and directories, file searching, file deletion etc.
The File object represents the actual file/directory on the disk.

There are following constructors to create a File object:

 File(File parent, String child);
 File(String pathname)
 File(String parent, String child)
 File(URI uri)

METHODS:

public String getName()
public String getParent()
