I have a problem with my address book program. I view all the entries from my address book, but they are displayed in different dialog 开发者_JAVA百科boxes. The first entry will be displayed in the first dialog box and then if i click "OK" the next entry will be shown in another dialog box. I want all entries to be shown in one dialog box.

here's my getter method:

public String getInfo(){
        String Info = "NAME\tADDRESS\tPHONE NO.\tE-MAIL ADD\n" +
                name +"\t " + add +"\t "+ phoneNo +"\t "+ email +"\n";
        return Info;
    }

here's how i display all information:

public void viewAll() {
        for (int i = 0; i < counter; i++) {
            JOptionPane.showMessageDialog(null, new JTextArea(entry[i].getInfo()));
        }
    }

hope you can help me... thanks in advance :)


In order to view all the entries inside one dialog box, you can try creating a string that will add up all the entries. See my code below:

 public String getInfo() {
   String content = "\t" + name + "\t"+ address + "\t\t" + telNo + "\t" + email;
   return content;
}


public class AddressBook
 public void viewAllEntry() {
        String addText = "NO\tNAME\tADDRESS\t\tTEL.NO\tEMAIL\t\n"; /<------HERE
        for (int i = 0; i <  addressBookEntryCounter; i++) {
            addText = addText+(i+1)+ entry[i].getInfo()+ "\n";     /<------HERE
        }
        JOptionPane.showMessageDialog(null, new JTextArea(addText));
    }

}

I'll take a wild stab in the dark here - you want ALL the contact information to be displayed in the same JOptionPane:

public void viewAll() {
    StringBuffer contactList = new StringBuffer();
    for (int i = 0; i < counter; i++) {
        contactList.append(entry[i].getInfo());
        contactList.append("\n");
    }
    JOptionPane.showMessageDialog(null, new JTextArea(contactList));
}
