Function and Constructors - 1 (Full question in description) | JAVA | ICSE

Write a program to create a class Function with the following functions:
1) void Fibonacci (): which calculate and print first 20 terms of the fibonacci series
2) void Profit (double, double): which input CP and SP of an article, calculate and print profit% or loss%, if CP and SP are equal then print "no profit no loss".

In the above video we understand the problem in more detail and then we learn how to write a Java program to solve it; along with dry run for better understanding.
