    <p>I'm about to go crazy. Maybe it's cause I've been working for 12 hours....but why will my if statment not evaluate to true when running <code>if (band.equals("4384")</code>?? I am printing <code>band</code> to the screen and it is reading <code>4384</code> but it will not evaluate to true. I've used .equals() so many times with out issue, what am I doing wrong?</p> <pre><code>public class Test { public static void main(String[] args) { // TODO Auto-generated method stub String endBand = " "; String str = "SCELL: UARFCN 4384, Prim. SC: 362, RSCP: 70, EcNo: 44"; endBand = getBandNumber(str); System.out.println("endBand is " + endBand); } // ************************************************ // Returns the current band that the device is on. // Currently only coded for 3G // ************************************************ private static String getBandNumber(String str) { // The string returned to str will be in the form of: // "SCELL: UARFCN 4384, Prim. SC: 362, RSCP: 73, EcNo: 33" // ^^^^ // String str = read_AT("AT+XL1SET=\"IRATSCEL?\"", 10); String band = " "; int begin = 0, end = 0; // Filter through the string to extrace the channel number for (int i = 0; i &lt; str.length(); i++) { char c = str.charAt(i); if (c == 'N' &amp;&amp; str.charAt(i + 1) == ' ') { begin = i + 1; } else if (c == ',') { end = i; break; } } band = str.substring(begin, end); System.out.println("band is " + band); if (band.equals("4384")) { band = "5"; } else { band = "2"; } return band; } } </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.
