Hence, the correct answer is option “B”.

Expert Solution & Answer

Explanation of Solution

Exception:

In Java, the exception is an object used to signal the unexpected error occurred during a program execution.
Exception is the error, which arises at run time and such errors can be handled in Java by exception handling.
The exception handling allows a method to throw an error to its caller and allowing the caller to manage that error.
- The called method itself must manage the error or end the program without this exception handling. But the called method does not know when error occurs.
- The library method helps to find the error, but only caller method knows how to handle that errors.

3.) File Encryption and DecryptionWrite a program that uses a dictionary to assign “codes” to each letter of the alphabet. For example: codes = { ‘A’ : ‘%’, ‘a’ : ‘9’, ‘B’ : ‘@’, ‘b’ : ‘#’, etc . . .}Using this example, the letter A would be assigned the symbol %, the letter a would be assigned the number 9, the letter B would be assigned the symbol @, and so forth. The program should open a specified text file, read its contents, then use the dictionary to write an encrypted version of the file’s contents to a second file. Each character in the second file should contain the code for the corresponding character in the first file. Write a second program that opens an encrypted file and displays its decrypted contents on the screen.

Returns an US standard formatted phone number, in the format of (xxx) xxx-xxxx the AreaCode, Prefix and number being each part in order. Testing Hint: We be exact on the format of the number when testing this method. Make sure you think about how to convert 33 to 033 or numbers like that when setting your string format. Reminder the %02d - requires the length to be 2, with 0 padding at the front if a single digit number is passed in.

Here are some notes to help you work the problem: • strcpy(char *dst, char *src) copies the string at address src (including the terminating '\0' character) to address dst. It does not check the size of the destination buffer. You will need to know the hex values of the following characters:
