.Test Cat class by creating 2 Cat instances

Expert Solution

Step 1: Algorithm:

Start.
Create a class named "Cat" with private instance variables (name, age, color, type) and a static variable (numberOfCats) to keep track of the number of cat objects created.
Define constructors for the Cat class to initialize its properties. One constructor takes all properties as arguments, and another constructor takes only name and age, with default values for color and type.
Implement methods for the Cat class, including "eat," "play," and getter methods for the instance variables.
Include a static method to get the number of cat objects created.
In the main method:
a. Create two Cat instances with different properties.
b. Call methods on the Cat instances to simulate cat behavior.
c. Print the number of cat objects created using the static method.
End.
