Creating a Fun Telephone Number Application!

How can we create a fun application to extract and display different parts of a telephone number?

Let's use the data provided to create a playful and interactive telephone number application!

Solution:

Let's dive into the code and understand how we can tokenize and manipulate the given telephone number:

The given code snippet is written in Java and allows us to input a telephone number in the format (555) 555-5555. By using the String method split, we can extract the area code, the first three digits, and the last four digits of the phone number as separate tokens.

We first prompt the user to enter a telephone number in the specified format. The code then splits the input string based on spaces to separate the area code and the rest of the phone number. We then further split the phone number based on the hyphen character to extract the first three digits and the last four digits.

After obtaining these tokens, we concatenate the first three and last four digits to form a single string representing the seven-digit phone number. Finally, we combine the area code and the seven-digit number with a space in between to create the full phone number.

By running the application, users can see the extracted area code, the phone number (without the area code), and the full phone number with the area code included. This playful application adds a fun twist to handling and displaying telephone numbers!
