Someone asked me to write an application that:

• Use an array to store the data for the different brands.
• Must have 4 additional index positions available for data entry so that I may be able to add
• Must ensure that PR or Plain Wrap is not duplicated in data entry
• Cannot use scanner
• You may choose to use 2 dimensional array (one class needed) or object of array(two classes needed)

Output:
• You will need to display the plain wrap number chosen and the corresponding Brands for that particular part.

So here it is:

Code:
