Given a file, and we have to check whether file can be read or not using Java program.

In this program, there is a file named "C.txt" which is saved in "E:\" drive in my system, so that path is "E:/C.txt".

To check that file can be read or not, there is a method canRead() of "File" class, it returns 'true' if file can be read or returns 'false' if file cannot be read.
