    <p>Whenever I type in a phone number, this program below that I wrote to format phone numbers from the user gives me back weird numbers that I did not even enter at all. Can someone please explain to me why I am getting such weird errors?</p> <p>I want it so when someone enters just 12345678978 it will format to 1-234-567-8978 If they enter 2345678978 it will format to 234-567-8978 And if they enter 5678978 it will change to 567-8978. I always get weird numbers that sometimes aren't even what I entered like 12345678978 I get 144-34--567- 2345678978 I get 153-567-8978 5678978 I get 162-8978</p> <p>I would really appreciate some help. Thanks.</p> <pre><code> import java.util.Scanner; public class Test3 { public static void main(String[] args) { Scanner y = new Scanner(System.in); String phoneNumber; int phoneNumberLength; System.out.print ("Please enter your phone number WITHOUT spaces or dashes: "); phoneNumber = y.nextLine(); phoneNumberLength = phoneNumber.length(); if (phoneNumberLength == 11) { phoneNumber = phoneNumber.charAt(0) + "-" + phoneNumber.charAt(1) + phoneNumber.charAt(2) + phoneNumber.charAt(3) + "-" + phoneNumber.charAt(4) + phoneNumber.charAt(5) + phoneNumber.charAt(6) + "-" + phoneNumber.charAt(7) + phoneNumber.charAt(8) + phoneNumber.charAt(9) + phoneNumber.charAt(10); } if (phoneNumberLength == 7) { phoneNumber = phoneNumber.charAt(0) + phoneNumber.charAt(1) + phoneNumber.charAt(2) + "-" + phoneNumber.charAt(3) + phoneNumber.charAt(4) + phoneNumber.charAt(5) + phoneNumber.charAt(6); } else { phoneNumber = phoneNumber.charAt(0) + phoneNumber.charAt(1) + phoneNumber.charAt(2) + "-" + phoneNumber.charAt(3) + phoneNumber.charAt(4) + phoneNumber.charAt(5) + "-" + phoneNumber.charAt(6) + phoneNumber.charAt(7) + phoneNumber.charAt(8) + phoneNumber.charAt(9); } System.out.println("So your phone number is " + phoneNumber + "?"); } </code></pre> <p>By the way. I know it is not formatted correctly but I am very confused with how stackoverflow allows you to add code. </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.
