what is the java code for the class and Write one or more tests that check that the method works as specified in all cases? intro: A Fibonacci series is a popular sequence of numbers. The first two numbers of this series are 0 and 1. After this, the next Fibonacci number is obtained by adding the previous two. Thus the Fibonacci sequence is 0,1,1,2,3,5,8,13,... A Fibonacci counter is a machine that counts Fibonacci numbers. Much like a step tracker, it can be started at any count. It can be incremented or decremented by 1 (count falling below 0 is invalid). Given a number ’n’, the nth Fibonacci number can be calculated directly using Binet’s formula: ???(?)=15√((1+5√2)?−(1−5√2)?) what to do: Write a class FibonacciCounter that represents a single Fibonacci counter. This class should contain the following: A constructor that takes the initial count value and initializes the object appropriately. A method that returns a FibonacciCounter object with its count incremented by 1. A method that returns a FibonacciCounter object with its count decremented by 1. If it cannot be decremented, it returns the object with the same count. A method that returns the current count of the counter. A method that returns the Fibonacci number corresponding to the current count. For each method: Design the signature of the method. Write Javadoc-style comments for that method. Write the body for the method. Write one or more tests that check that the method works as specified in all cases. You may find the Math class useful for this lab. Look at the documentation for the Math class and try to understand how to use it.
