Scenario:

A grocery store manager wants to establish a system to

manage product inventory. The manager would like to use the

system to input information such as product code, product

name, quantity in stock, minimum reorder level, and shelf

number for each product. The system will categorize products

based on their type, identified by a product code prefix as

shown in Table $1.$

Table $1$

Product Code Prefix Category

The product code must start with the specified prefix followed

by $4$ digits $($e$.$g$.,"$FD$0123"$ for a food product$).$ Ensure that the

quantity in stock and minimum reorder level are non$-$negative

values. The shelf number should be a value in the range of

$100-990.$ Allow the manager to rectify any invalid input and

continue the data entry process until they decide to stop.

Once the manager finishes entering records, display the total

quantity in stock for each product category.

Question $1$:

You are required to perform $3$ tasks.

Task $1$: IPO Table

Create a table to divide the problem into $3$ different

components $($Input$,$ Output & Processing$).$

Task $2$: Solution Algorithm

Design a solution algorithm using flow$-$charts or

pseudo codes based on the preceding IPO table.

Task $3$: Checking the Solution Algorithm

Perform desk checking with $2$ sets of input test data.

Question $2$ :

Program Implementation

Convert your solution algorithm to a complete Java program.
