Chapter 20.5, Problem 14SC

Explanation of Solution

To make a backup copy of a file:

Obtain a path for the backup file first.

Alter the suffix as follows,

Path q = Paths.get(p.toString().replace(“.txt”, “.bak”));

The user can also alter the suffix as is usual in Linux, insert a “~” to the file name:

Path q = Paths.get(p.toString() + "~");

To copy a file, the method “copy()” is used as follows,

Files...

Explanation of Solution

To overcome the problem:

To copy a file, the method “copy()” is used as follows,

Files.copy(p, q);

If “p” does not exist, the function invocation on the “copy()” method throws an exception.

Similarly, if the backup file “q” is already exists, then also the call to the method “copy()” throws an exception.

To overcome the problem of file existence, first delete the file using the method “delete()”, if it already exists...
