    <p>If I try to compile this code I get an error that reads "local variable phoneNumber1 is access from within inner class; needs to be declared final. </p> <p>Quite simple how do I fix this so it doesn't have this compile error? I've read the technical spec for it, I've gone through the tutorial, but I'm still at a loss. I hope nobody was paid to write this thing.</p> <pre><code>public class LocalClassExample { static String regularExpression = "[^0-9]"; public static void validatePhoneNumber(String phoneNumber1, String phoneNumber2) { int numberLength = 10; class PhoneNumber { String formattedPhoneNumber = null; PhoneNumber(String phoneNumber){ // numberLength = 7; String currentNumber = phoneNumber.replaceAll( regularExpression, ""); if (currentNumber.length() == numberLength) formattedPhoneNumber = currentNumber; else formattedPhoneNumber = null; } public String getNumber() { return formattedPhoneNumber; } public void printOriginalNumbers() { System.out.println("Original nubmers are " + phoneNumber1 + " and " + phoneNumber2); } } PhoneNumber myNumber1 = new PhoneNumber(phoneNumber1); PhoneNumber myNumber2 = new PhoneNumber(phoneNumber2); myNumber1.printOriginalNumbers(); if (myNumber1.getNumber() == null) System.out.println("First number is invalid"); else System.out.println("First number is " + myNumber1.getNumber()); if (myNumber2.getNumber() == null) System.out.println("Second number is invalid"); else System.out.println("Second number is " + myNumber2.getNumber()); } public static void main(String... args) { validatePhoneNumber("123-456-7890", "456-7890"); } } </code></pre>

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.
