Question

Write a java program to implement a password testing system. Your program will use a loop to prompt a user to enter a password and repeat until the password passes five tests. It is long enough (8 or more characters) 1.

Answer 1

A Java program can implement a password testing system using a loop that requires user input until the password condition of being at least 8 characters long is met, utilizing a while loop and the length() method.

Step-by-step explanation:

In Java, a password testing system can be implemented using a loop that continues to prompt the user for input until the password meets certain conditions. Below is an example of a simple Java program that checks if the entered password is at least 8 characters long, thus satisfying one of the tests for password strength.

import java.util.Scanner;

public class PasswordTester {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String password;

while (true) {
System.out.print("Enter a password: ");
password = scanner.nextLine();

if (password.length() >= 8) {
System.out.println("Password is long enough.");
break;
} else {
System.out.println("Password is too short. It must be at least 8 characters.");
}
}

scanner.close();
}
}

This program will continuously ask the user to enter a password until they provide one that meets the length requirement. The while loop is used to repeat the input prompt and the length() method of the String class tests the password length.
