Rewrite Exercise 17.10 with a GUI, as shown in Figure 17.21a.

Suppose you want to back up a huge file (e.g., a 10-GB AVI file) to a CD-R. You can achieve it by splitting the file into smaller pieces and backing up these pieces separately. Write a utility program that splits a large file into smaller ones using the following command:

java Exercise17_10 SourceFile numberOfPieces

The command creates the files?SourceFile.1,?SourceFile.2, . . . ,?SourceFile.n, where?n?is?numberOfPieces?and the output files are about the same size

(a) The program splits a file.
