Question

You are going to create a console based program to keep track of a small business that sells Doodads.

First you will need to create a class Doodad that keeps track of two integers and two Strings.

Next, create a constructor for the Doodad.

Next, add getters and setters for each of the fields (two integers and two Strings).

You need to use Doodad.java (see the starter code)

Inside your main method ask the user to read in the two integers and two Strings. Create a Doodad object and add it to an array of 100 Doodad objects. Allow the user to keep entering in Doodad objects until the user wishes to quit.

Once the user is done entering Doodad objects, show the information about the Doodads they entered.

You will show the first number, followed by a space, followed by the first word.

Answer: Hey dear student finds the solution of your query, if you have any doubt feel free to ask. Thanks!!

C++ Code: this code had Doodad class has two integer type data members ,two String type data members. Class has a parametrized constructor. In Main, read values for integers and strings and create array of object Doodad class and passing the values to set data members of the class , ask from user if he wants to exit from input and print all entered values.

Any query asks in the comment box.
