Question

Create a java class with name Cat.

Instructions for Cat class:

This class is modeled after a Cat. You should have instance variables as follows:

• The Cat’s name
• The number of mice caught by the Cat.
• Whether or not the Cat is secretly plotting to kill you

Note that you will need to choose both good types and meaningful identifiers for each of these instance variables. You may also assume that the Cat is not automatically always secretly plotting to kill you. Sometimes the plot is out in the open.

Your class should contain two constructor methods. A default constructor and a constructor that allows you to instantiate an object of the Cat class and choose initial values for each of the three instance variables.

Your class should also contain accessor and mutator methods for all three instance variables (Cat’s really don’t care what you call them, they won’t listen regardless, and it is potentially possible that it will stop plotting to kill you, although this is both unlikely and only temporary).

You will also need to override the toString method to work properly for the class. It should return a String containing the Cat’s name, the number of mice caught by the Cat, and whether or not the Cat is secretly plotting to kill you.
