Zip-code-converter

This project consists of two Java classes, Zipcode and ZipTest, which provide functionality for converting between ZIP codes and barcodes.

Zipcode Class

The Zipcode class provides methods to convert ZIP codes to barcodes and vice versa. It contains the following methods:

1. Zipcode(int z): Constructor that initializes a Zipcode object with an integer ZIP code.
2. Zipcode(String b): Constructor that initializes a Zipcode object with a barcode string.
3. getZIPcode(): Converts the barcode to a ZIP code string.
4. getBarcode(): Converts the ZIP code to a barcode string.
5. createCheckDigit(): Calculates the check digit for the ZIP code.
6. arrayToString(String[] barCode): Converts a string array representing a barcode to a single string.
7. arrayToString(int[] zipCode): Converts an integer array representing a ZIP code to a single string.
8. isValidCheckDigit(String barcode): Checks if the check digit of the barcode is valid.

ZipTest Class

The ZipTest class serves as a tester program for the functionality provided by the Zipcode class. It allows users to interactively test the conversion between ZIP codes and barcodes.

Usage

To use the ZipTest program:

Compile the program. Run the compiled program. Follow the prompts to enter either a ZIP code or a barcode. The program will display the corresponding barcode or ZIP code based on the input provided
