Here are my code files. Any help would be appreciated. We are supposed to use hashcode, the contains ()method, and also collections sort() to sort the list by stock number. I need to be able to store it in a 2d array which is giving me the most trouble right now.

O Assignment: Create a Java class named InventoryItem that contains the following members: Properly named variables of appropriate data types for the following information: Stock number (alpha-numeric), item description, item price Create a Java class named Homework7 that performs the following: This file will include your mainline logic (e.g. main method) Given the activity diagram provided in Figure 1 below, create the necessary Java code to satisfy the algorithmic requirements The conditional testing of y input must be case invariant O O O Note: Your program should create the correct output and repeat correctly using data values entered by the user. Table 1 below shows the example input/output used by MISGrader's test case, there are other hidden test cases that you do not have knowledge of the values provided. What is item #1's stock number? 123456 What is item #1's description? Pencil What is item #1's price? 0.59 Are there any other items to add to this transaction? (Y/N) Y What is item #2's stock number? a789z234 What is item #2's description? Eraser What is item #2's price? 2.99 Are there any other items to add to this transaction? (Y/N) Y What is item #3's stock number? d99e-ef What is item #3's description? Paper, college-rule What is item #3's price? 0.89 Are there any other items to add to this transaction? (Y/N) N Did this transaction contain item #123456: true Item 123456 hashcode is: 1450575490 Item a789z234 hashcode is: 481530223 Item d99e-ef hashcode is: 243612588 InventoryItem [sku=123456, desc=Pencil, price=0.59] InventoryItem [sku=a789z234, desc=Eraser, price=2.99] InventoryItem [sku=d99e-ef, desc=Paper, college-rule, price=0.89] Table 1 - Example program input & output act Activity diagram Repeat n times M Input "What is item #" value "'s stock number?' Store stock number in a local variable LIN Output "Did this transaction contain item #123456" value Input "What is item #" value's description?" Store description in a local variable Input "What is item #" value "'s price?" Store price in a local variable Output "Item" value" hashcode is:" value More items in the collection?
