    <p>Everything of my guessing game is alright, but when it gets to the part of asking the user if he/she wants to play again, it repeats the question twice. However I found out that if I change the input method from nextLine() to next(), it doesn't repeat the question. Why is that?</p> <p>Here is the input and output:</p> <pre><code>I'm guessing a number between 1-10 What is your guess? 5 You were wrong. It was 3 Do you want to play again? (Y/N) Do you want to play again? (Y/N) n </code></pre> <p>Here is the code:(It is in Java) The last do while loop block is the part where it asks the user if he/she wants to play again. </p> <pre><code>import java.util.Scanner; public class GuessingGame { public static void main(String[] args) { Scanner input = new Scanner(System.in); boolean keepPlaying = true; System.out.println("Welcome to the Guessing Game!"); while (keepPlaying) { boolean validInput = true; int guess, number; String answer; number = (int) (Math.random() * 10) + 1; System.out.println("I'm guessing a number between 1-10"); System.out.print("What is your guess? "); do { validInput = true; guess = input.nextInt(); if (guess &lt; 1 || guess &gt; 10) { validInput = false; System.out.print("That is not a valid input, " + "guess again: "); } } while(!validInput); if (guess == number) System.out.println("You guessed correct!"); if (guess != number) System.out.println("You were wrong. It was " + number); do { validInput = true; System.out.print("Do you want to play again? (Y/N) "); answer = input.nextLine(); if (answer.equalsIgnoreCase("y")) keepPlaying = true; else if (answer.equalsIgnoreCase("n")) keepPlaying = false; else validInput = false; } while (!validInput); } } } </code></pre>

    1. COTry to not use a `do-while`... People tend not to use them because they are kind of unusual. Also, try including in your question your input and the output that is produced.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
