Help me out on the following program for my project. Its urgent . thank you

Question

Create a class ToyCollection that stores information about different toys in a toy shop. The information to be stored about a single toy is,
- Toy identification as String
- Name of the toy as String
- Short description about the toy as a String
- Price of the toy as float
- Quantity of the toy in hand as short integer.
This class contains following methods,
- Constructor method that assigns user input values to above mentioned variables.
- main ( ) method that creates array of 4 objects of ToyCollection class and that takes input for all above details from the user and
calls method to check validity of Quantity and Price values. If all values are valid then create the objects and display the details
for all 4 toys.
- Method that checks validity of quantity and price. If the quantity is 0 or negative then method should throw user defined
exception with appropriate message and come out of program. Similarly if the price is 0 or negative then it should throw user defined exception with appropriate message and come out of program.
- Method that displays all details about a single toy in the following format, e.g. Here Total price should be calculated.
Toy Identification : S-1
Toy Name : Small Scooter
Toy Description : Ordinary 3 wheeler scooter
Toy price : 650.50
Quantity in hand : 3
Total price of Toys : 1951.50
