And then add the two digits. so 1 + 2 = 3.) I'm having problem with the code that its not reading where it replace the lower to upper and vice versa. this is my code so far: import java.util.Scanner;public class Convert {public static void main(String[] args) {Scanner input = new Scanner(System.in);String original, converted;while (true) {System.out.print("Original String (input):");original = input.nextLine();if (original.equals("q") || original.equals("Q")) {break;}char[] chars = original.toCharArray();for (int i = 0; i <...
