provide flowchart for the following code public class MorseCode_Converter { public static boolean isValid(String str) { char ch; for(int i = 0; i < str.length(); ++i) { ch = str.charAt(i); if(!Character.isUpperCase(ch) && ch != ' ' && ch != ',' && ch != '.' && ch != '?' && !Character.isDigit(ch)) { return false; } } return true; } // main function public static void main(String args[]) { // declare variable String input; // to get user input Scanner scan = new Scanner(System.in); // display while (true) { System.out.println("Enter a String to get its Equivalent Morse Code"); input = scan.nextLine(); if(isValid(input)) { break; } System.out.println("Input is not valid. Try again!"); } // create an object Morse Mr = new Morse(input); // display System.out.println(" Original String ."); System.out.println(Mr.getOriginal() + " "); // display System.out.println("Equivalent Morse Code ."); System.out.println(Mr.getMorseCode()); } }
