Start by downloading CS201_Lab05.zip and importing it into Eclipse. You should see a project called CS201_Lab05.
You will make changes to the class called ReadFile.
Your Task
Complete the progam so that it prompts the user for the name of a file, and then prints the contents of the file to System.out.
There are several important requirements:
- The main method must not be declared to throw any kind of exception.
- The program must not test whether or not the requested file exists before attempting to open it.
- The program must use a try/finally block to make sure that the reader or input stream reading the file is closed before the program exits.
Assume that the file myFile.txt contains the following contents:
Oh freddled gruntbuggly
Thy micturations are to me
As plurdled gabbleblotchits on a lurgid bee.
Groop I implore thee, my foonting turlingdromes
And hooptiously drangle me with crinkly bindlewurdles,
Or I will rend thee in the gobberwarts with my blurglecruncheon,
See if I don't!
Here is an example session showing a file being printed successfully (user input in bold):
Which file? myFile.txt Oh freddled gruntbuggly Thy micturations are to me As plurdled gabbleblotchits on a lurgid bee. Groop I implore thee, my foonting turlingdromes And hooptiously drangle me with crinkly bindlewurdles, Or I will rend thee in the gobberwarts with my blurglecruncheon, See if I don't!
Here is another example session showing what happens when the user enters the name of a nonexistent file:
Which file? nonexistent.txt Error: nonexistent.txt (No such file or directory)
Hints
Use a try/catch block to handle an IOException or FileNotFoundException that might occur. Print the error message from the catch block. You can call the getMessage method on the caught exception object to get a string containing a textual description of the error that caused the exception.
Submitting
When you are done, submit the lab to the Marmoset server using either of the methods below.
