- For this Bank Teller's program, your assignment is to add in methods after each case in Java using Netbeans 8.2.arrow_forwardFor this problem you will write a method that computes the number of boxes in a pyramid of boxes based on the number of boxes in the base. The boxes in each layer of the pyramid are stacked directly on top of one another (i.e. not offset between two boxes below). For example, below are shown two pyramids, one with base 5 and one with base 6. [] [][] [][][] [][][][] [][][][][] [][][][][][] Implement and test the computePyramidBoxes() method in the PyramidBoxCount class. When testing the computePyramidBoxes() method you should be sure to have at least one test method for each base case and at least one test method for each recursive case in your program.arrow_forwardWrite a JAVA CODE with a main() method that asks the user to input an integer array of 10 elements.Next, create three methods described below.

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.
