Besides main() this program has one method that computes the amount of raise and the new salary for an employee. The current salary and a performance rating (a String: "Excellent", "Good" or "Poor") are input. import java.util.Scanner; public class Salary { public static void main (String[] args) { Declare variables Prompt for and read current salary and rating For an excellent rating compute raise as 0.06 of current salary For a good rating compute raise as 0.04 of current salary For a poor rating compute raise as 0.015 of current salary You can use abc.equals(“xyz”) to verify the rating read For an invalid rating display an appropriate message and display the salary without change; otherwise, compute and print new salary and raise amount main() must display the message } } Note:- Please type and execute this java program and also need an output for this java program as soon as possible.

The Java code provides a Class named Function in Function.java that has a static method named f that takes a double argument and returns the value of . It also has a static method named fprime that takes a double argument for x and returns the value of the slope of f(x). The slope of f(x) can be calculated as . Implement this method. public class Function { public static double f(double x) { return Math.pow(x,3) - 3 * x; } public static double fprime(double x) { // your code goes here } }
