I want to use switch statements in my program. I've got my code working already but want to use switch statements. How do I do it? Here is what i got so far. import java.util.Scanner; public class ReviewApplication { public static void main(String[] args) { Scanner keyboard = new Scanner(System.in); double sum = 0; double difference = 0; double product = 0; double divide = 0; double[] array = new double[5]; System.out.print(" Enter 5 floating point numbers: "); for (int i = 0; i < array.length; i++) { array[i] = keyboard.nextDouble(); sum = sum + array[i]; } char choice; while (1==1) { choice = processMenu(); if(choice == 'a') { System.out.println("the sum is " + sum);} else if (choice =='s') { difference = array[0]; for (int i = 0; i < array.length; i++) difference = difference - array[i];
