    <p>I am creating a rock paper scissors game for class at school. I got everything to work, except for setting up something to restate the question when an invalid choice is answered. I figured a do...while statement was best here, but I realized that I am calling on a variable within the "do" part of the loop. So, since it's calling on something from another loop, it can't find that variable. Also, in my while statements, did I correctly list the variables that are acceptable? I'm pretty sure I just made that part up.</p> <p>Thanks so much for your help guys!</p> <pre><code>import java.util.Scanner; public class RockPaperScissorsTest { public static void main(String[] args) throws Exception { Scanner input = new Scanner(System. in ); do { System.out.println("Player 1, choose 1 for rock, 2 for paper, or 3 for scissors."); int P1 = input.nextInt(); } while (P != 1; P1 != 2; P1 != 3); System.out.println(""); System.out.println(""); System.out.println(""); do { System.out.println("Player 2, choose 1 for rock, 2 for paper, or 3 for scissors."); int P2 = input.nextInt(); } while (P2 != 1; P2 != 2; P2 != 3); if (P1 == 1 &amp; P2 == 1) System.out.println("It's a tie!"); if (P1 == 1 &amp; P2 == 2) System.out.println("Player 2 wins!"); if (P1 == 1 &amp; P2 == 3) System.out.println("Player 1 wins!"); if (P1 == 2 &amp; P2 == 1) System.out.println("Player 1 wins!"); if (P1 == 2 &amp; P2 == 2) System.out.println("It's a tie!"); if (P1 == 2 &amp; P2 == 3) System.out.println("Player 2 wins!"); if (P1 == 3 &amp; P2 == 1) System.out.println("Player 2 wins!"); if (P1 == 3 &amp; P2 == 2) System.out.println("Player 1 wins"); if (P1 == 3 &amp; P2 == 3) System.out.println("It's a tie!"); } } </code></pre>

    3. COWhat do you mean by "if P1==P2." Should I redo my conditions in the while statement?

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.
