    <p>I have this program:</p> <pre><code>import java.util.*; import java.io.*; public class Oblig2 { public static void main (String[] args) { final Scanner input = new Scanner (System.in); int menyvalg=0; Meny menyen = new Meny(); menyen.meny(); } } //Selve menyen til programmet i en egen klasse. class Meny { PrintWriter fil; Scanner input = new Scanner (System.in); public void meny() { try{ fil=new PrintWriter(new FileWriter("fugler.txt")); } catch (IOException e) { System.out.println("Filen finnes ikke"); } int menyvalg=0; int menykall=1; //Menyen vil her bli repetert helt til en taster inn 4 og endrer menykall til 0. do{ //Selve menyen vil bli repetert helt til brukeren velger en av menyens alternativer. do{ System.out.println("====== Meny for registrering av fugleobservasjoner ====="); System.out.println("\n1. Registrer en fugleobservasjon"); System.out.println("2. Skriv ut alle fugleobservasjoner av en type"); System.out.println("3. Skriv ut alle fugleobservasjoner på ett bestemt sted"); System.out.println("4. Avslutt systemet"); System.out.println("\nVennligst velg en aksjon: "); menyvalg = input.nextInt(); } while(menyvalg &lt; 1 || menyvalg &gt; 4); switch (menyvalg){ case 1: registrering(); break; case 2: case 3: case 4:menykall=0; } }while(menykall&gt;=1); } void registrering () { System.out.println("Velkommen til registreringen av fugleobservasjoner."); System.out.println("Begynner registreringen (Lagrer seg i filen fugler.txt): "); try { fil = new PrintWriter(new FileWriter("fugler.txt", true)); System.out.println("\nVennligst tast inn fugletypen: "); String fugletype = input.next(); fil.write(fugletype + ","); System.out.println("Tast inn fuglens kjonn (M/H/X): "); char fuglekjonn = input.next().charAt(0); fil.write(fuglekjonn + ","); System.out.println("Tast inn observasjonslokasjon: "); String lokasjon = input.next(); fil.write(lokasjon + ","); System.out.println("Tast inn dato for observasjon (Som en string på formen mai2012): "); String dato = input.next(); fil.write(dato); fil.close(); }catch(Exception e){ System.out.println("Åpning av fil feilet"); } } } </code></pre> <p>And when I run it, and then through case 1 which is a script for registering information into a .txt file called fugler.txt. Te problem is that everytime I register a new bird into this I want it to get placed nice and sweetly at the end of the file. But it doesn't. it overwrites the entire file. And why does it do that, when I have placed true at the end of the opening of the file?</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.
