In this activity, you will practice with file I/O and exception handling.

1. Start a new project and name it FileIO. Copy the english text and save the file in your project directory.

2. Open FileIO.java, add a new method as follow:

public static void copyFile(String fileName, String fileName2)

3. Implement this method, so that it reads each line from a file (named fileName) and writes it into a new file (named fileName2). Make sure that you use try catch block to handle the exceptions.

4. After you implement this method, add the following statement to the main() method and run your project.

copyFile("english.txt", "copy.txt");

If everything works, you should see a copy of the original file created in your project folder.

5. In your FileIO.java, add another method:

public static void translateFile(String fileName, String fileName2)

6. Implement this method, so that it reads lines from a file as input and translates each word to "Pig Latin". The rule is to convert a word by removing the first letter, placing that letter at the end of the word, and then appending "ay" to the word. Here is an example:

English: HOW ARE YOU

Pig Latin: OWHAY REAAY OUYAY

You will use String methods. If you are not familiar with the String class, browse its API here:

https://docs.oracle.com/javase/9/docs/api/java/lang/String.html (Links to an external site.)

In particular, read about the following methods:

• subString(int index)
• charAt(int index)

Hint: to concatenate two strings or a string with a character, you may use "+" sign.

7. After you implement this method, add the following statement in the main() method to test it:

translateFile("english.txt", "piglatin.txt");

If everything works, you should see a new file created in your project folder, and the content of the file is the pig latin version of the original file.

english.txt
