Pet Clinic total earnings Java program<\/h1>\n

Problem Statement<\/h3>\n

A pet doctor treats dogs, cats, and cows in his pet clinic. Write a simple Java program to calculate his earnings in the clinic if he treats 25 dogs, 10 cats, 2 cows in a day. Use an object-oriented approach.<\/p>\n

Treatment Menu: Fee<\/p>\n

Dog\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 100$<\/p>\n

Cat\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 250$<\/p>\n

Cow\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 1250$<\/p>\n

Solution:<\/h3>\n

Total Pet Doctor Earnings $:7500<\/strong><\/p>\n

Calculation = ( 25 * 100)\u00a0 + ( 10 * 250 ) + ( 2 * 1250 )<\/strong><\/p>\n

Single inheritance<\/strong><\/h3>\n
All derived classes have Animal as the super class. We have used single inheritance for the derived classes.\u00a0Single inheritance is a mechanism that allows a class to only inherit from a single base class.<\/p>\n

 <\/p>\n
Further Enhancements<\/h3>\n
We can make further enhancements to the program. Consider designing an interface contract for the treatable animals.<\/p>\n
Let’s name The interface as ITreatable.<\/p>\n
public interface ITreatable {<\/strong>
\npublic int getTreatmentFee();<\/strong>
\n}<\/strong><\/p>\n
Now all treatable animals can implement this interface.<\/p>\n","protected":false},"excerpt":{"rendered":"
