    <p>I'm just starting out using Java. And I came across this issue :</p> <p>This is my code : </p> <pre><code>import java.util.Scanner; public class FormatageValeurNumerique { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub System.out.println("Entrez une valeur reelle :"); Scanner in = new Scanner(System.in); float x = in.nextFloat(); // System.out.printf("La valeur reelle est, apres formatage : %.5+,f", x); // Gives exception ? Why ? // System.out.printf("La valeur reelle est, apres formatage : %+.5,f", x); // Gives exception ? Why ? System.out.printf("La valeur reelle est, apres formatage : %+,.5f", x); } } </code></pre> <p>Outputs :</p> <p>Entrez une valeur reelle : 315136.23 La valeur reelle est, apres formatage : <strong>+315,136.21875</strong></p> <p><strong>And this is what is expected :</strong></p> <p>Formatage de valeurs numériques</p> <p>Écrivez un programme qui demande à l’usager une valeur réelle et qui l’affiche à l’écran en s’assurant d’avoir au moins 5 chiffres après la virgule, en forçant l’apparition du signe et en incluant le groupement de chiffres. </p> <p>L’affichage obtenu doit être semblable au suivant:</p> <p>Entrez une valeur réelle : 315136.23 La valeur réelle est, après formatage : <strong>+315,136.23000</strong></p> <p><strong>The numbers do not match... any ideas why ?</strong></p> <p>Also if someone can explain why I'm getting exceptions depending on how I write out the flags ? Is there a priority to respect ? </p>

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.
