Java

Scanner scanner3 = new Scanner(System.in);
    String passwordConfirm = scanner3.nextLine();
    
    if (passwordConfirm.equals(password) ) {
      System.out.println("Your password has been confirmed");
    }
      else {
        System.out.println("The passwords do not match, please try again below");
        
       Scanner scanner5 = new Scanner(System.in);
       String passConfirm = scanner5.nextLine();
       
       if (passConfirm.equals(password) ) {
         System.out.println("The passwords now match, thank you");
         
         scanner5.close(); 
       }
         else {
           System.out.println("The passwords still do not match, please reload the app to try again");
          
           /**This line of code exits the Java program if the password is still not confirmed, forcing the user to reload the program to try again**/
           System.exit(0);
         }
      }
