Reading text data from a file and writing text data to a file are common programming tasks. This discussion has you look at the most common approaches to file input and output. Since problems at runtime are always possible when working with files, the code for this discussion also demonstrates basic exception handling using try-and-catch blocks.
Download and unzip the course file TextFile.zip. Open the project in NetBeans.
Build and run the program a couple of times to see how it works. Then, read through the source code to see how the file access and exception handling work.
The program includes exception handling, but it is not triggered during normal operation. How could the working of the exception handling be tested?
