PLEASE WRTE JAVA CODE

2. A. Modify your program to contain a package with the following two classes: ScientificCalculator and Driver. The class ScientificCalculator will contain the following static methods: displayMenu, calculate Power, calculateSquareRoot, calculateMaximum, and calculateLogarithm. The method displayMenu prints out the menu; whereas the other methods compute the corresponding operations. To implement these methods, you are free in your design to calculate the related operations (either code the algorithms of the operations yourself or call the corresponding methods of class Math). The class Driver will just contain a main method to test the methods of class ScientificCalculator. Illustrate the main method similar to the one in your first program. B. Modify your class ScientificCalculator to contain another static method called calculateFibonacci. This method shall take an integer input value and return the fibonacci number corresponding to that input. Try to use a recursive algorithm to compute the fibonacci value
