Write an application that prompts the user for a password that contains at least two uppercase letters, at least three lowercase letters, and at least one digit. Continuously reprompt the user until a valid password is entered. Display a message indicating whether the password is valid; if not, display the reason the password is not valid. Save the file as ValidatePassword. java

import java. util. Scanner;

public class ValidatePassword {

public static void main (String[] args) {

/ / TODO Auto-generated method stub

Scanner scanner = new Scanner (System. in);

do {

System. out. print ("/nEnter Password:");

String password = "";

password = scanner. nextLine ();

int upperFound = 0, lowerFound = 0, digitFound = 0;

for (char c : password. toCharArray ()) {

if (Character. isUpperCase (c)) {

upperFound++;

} else if (Character. isLowerCase (c)) {

lowerFound++;

} else if (Character. isDigit (c)) {

digitFound++;

}

}

String errorMessage = "";

if (upperFound < 2) {

errorMessage + = "/n uppercase letters";

}

if (lowerFound < 2) {

errorMessage + = "/n lowercase letters";

}

if (digitFound < 2) {

errorMessage + = "/n digits";

}

/ / System. out. println (errorMessage);

if (errorMessage. length () > 1) {

System. out

. println ("The password did not have enough of the following: "

+ errorMessage);

} else {

System. out. println ("Valid password");

break;

}

} while (true);

}

}
