A file or a directory in the file system is represented by two abstract concepts in java. These abstract concepts are java.io.File and java.nio.file.Path .

The File class represents a file in the file system whereas the interface Path represents the path string of the file. In this tutorial we look at various operations on File or Path. We get a handle on the File using

Syntax :

File file = new File("c:\\filefolder\\file.txt");

But in your case first check whether location is available through file explorer,and use the same address.
