Currently, the code throws out NoProductException if an invalid path is specified when deleting a product.

https://github.com/rohanrajpal/advanced-programming-tutorials/blob/main/tut-6/Database.java#L53

Create a new exception to do the same.

When we give unexpected input, program get terminated. I think to handle these exception, program should show error message then ask for input again.
I would like to contribute to this by handling these exception. If you want these exception to be handled in some other way, please let me know.

Hi! ✋
In tut5/Main.java while we are checking if a target has been hit or not, we need not iterate over all the previous hits to check, rather keep a HashMap / HashSet for the same in order to achieve a better time complexity!

While running tut-7 i found a bug that it hero hp can go negative. I think this should not be less than zero as mentioned in tut-7 pdf.

You choose to attack
Your Hp: 60/100Monsters Hp :180/200
Monster attack!

   Monster attack!
   Your Hp: -4/100Monsters Hp :180/200
   You have died start over

5. Go to Location 6

When i run tut-6 it is really difficult to understand what to enter because it is not printing what we have to enter. Also sometimes we need to enter 2 and 3 inputs together so it is really confusing what we have to enter.

When we create multiple user in program it don't ask for username. It is because you used nextInt in tut7/Game.java and tut7/Menu.java, while taking integer input. I think by taking input as string and parsing it using Integer.parseInt() function to int will resolve this.

condition of checking equality might be wrong.

tut-5/SoftToy.java

System.err.println("Enter a valid type");
System.exit(0);

Above error handling is been done only in SoftToy class. This should also been done in CandyBar and Statitems Classes.
