## Lab Tasks

### Task 1: Complete your blog!

In the previous lab, we've created a simple blog, you should complete this blog, you should add a class named `Category`, this class will hold the posts of this category, you could only list posts in a certain category, assume that each category stores its posts in a different folder.

You will have a static list of categories:
- General
- Personal
- Work
- Notes
- Java Notes

### Task 2: Simple Accounting program.
In this task, you should create a simple accounting program, in the main menu of the application you will have the following options:

1. Create Receipt
2. Add Item
3. Edit Item
4. Delete Item
5. Exit

if you entered `1`, you should allow the user to add item code and quantity, and if the user adds `0` as the code the program will print the receipt.

Enter Selection: 1
  Enter Item Code: 100
  Enter Item Qty : 2
  Enter Item Code: 101
  Enter Item Qty : 1
  Enter Item Code: 110
  Enter Item Qty : 1
  Enter Item Code: 0
------------Receipt------------
ITEM NAME         QTY      PRICE        TOTAL
Item 100 Name      2       1.00          2.00
Item 101 Name      1       5.00          5.00
Item 110 Name      1       10.00         10.00

if the user entered `2`:

Enter Selection: 2
  Enter Item Code : 101
  Enter Item Name : Item 101 Name
  Enter Item Price: 1

  Enter Item New Name : (If empty leave it as it is)
  Enter Item New Price: 2
Item saved!

if the user entered `4`:

Enter Selection: 3
  Enter Item Code : 101

All items should be saved in a text file `items.txt`.

Think about your program, and design your UML digram, then solve the code.
