Kleiner Downloader

[Andre267]

Schönen guten Abend,

ich bin gerade dabei, einen kleinen Downloader für meine Berichtshefte etc. zu basteln.
Ich weiß nur gerade nicht wie ich dem Downloader sage das er das Berichtsheft XYZ in Ordner C:\Users speichern soll.

(Wie das ActionPerformed Event für den Button geht weiß ich.)

Weiß jemand wie das geht?

Etwas Code wäre hilfreich. Deine Beschreibung alleine ermöglicht noch nicht zu erkennen, wo das (Verständnis?)Problem liegen könnte.

Hier ist mein Code bis jetzt:

public class DownLoader extends javax.swing.JFrame {

    /**
     * Creates new form DownLoader
     */
    public DownLoader() {
        initComponents();
    }

    /**
     * This method is called from within the constructor to initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is always
     * regenerated by the Form Editor.

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        jLabel1.setFont(new java.awt.Font("Tahoma", 1, 14)); // NOI18N

        jLabel2.setText("Speicher Ort:");

Und im Anhang sieht man wie das ganze aussieht.

Wie lade ich z.B. Berichtsheft 1 runter? (Ist auf Server xyz z.B. http://www.maxmusterman.de/Berichtsheft_1.doc)

java datei downloaden

Dies sollte doch erst mal brauchbare Ergebnisse liefern.
