Body
You should compare strings using <code>equals</code> instead of <code>==</code>. I.e. change <pre><code>if ((list.get(i) == "x")) ^^ </code></pre> to <pre><code>if ((list.get(i).equals("x"))) ^^^^^^ </code></pre> <code>==</code> compares references, while <code>.equals</code> compares actual content of strings. <hr> Related questions: <ul> <li><a href="https://stackoverflow.com/questions/513832/how-do-i-compare-strings-in-java">How do I compare strings in Java?</a></li> <li><a href="https://stackoverflow.com/questions/6730907/java-compare-strings">Java Compare Strings</a></li> <li><a href="https://stackoverflow.com/questions/4700357/comparing-strings-in-java">Comparing strings in Java</a></li> <li><a href="https://stackoverflow.com/questions/5116595/compare-two-strings-java">https://stackoverflow.com/questions/5116595/compare-two-strings-java</a></li> <li><a href="https://stackoverflow.com/questions/3805601/whats-the-quickest-way-to-compare-strings-in-java">What's the quickest way to compare strings in Java?</a></li> <li><a href="https://stackoverflow.com/questions/4064633/string-comparison-in-java">String Comparison in Java</a></li> <li><a href="https://stackoverflow.com/questions/767372/java-string-equals-versus">Java String.equals versus ==</a></li> <li><a href="https://stackoverflow.com/questions/2220400/compare-two-strings-in-java">How do I make my string comparison case insensitive?</a></li> <li><a href="https://stackoverflow.com/questions/5505981/comparing-strings-in-java">comparing strings in java</a></li> <li><a href="https://stackoverflow.com/questions/2704956/strings-dont-seem-to-be-equal-in-java-on-android-even-though-they-print-the-sam">Strings don't seem to be equal in Java on Android, even though they print the same</a></li> <li><a href="https://stackoverflow.com/questions/6940521/comparing-java-strings-with">Comparing java Strings with ==</a></li> <li><a href="https://stackoverflow.com/questions/6607888/how-can-i-compare-string-value-with-arraylist-of-string-type-in-java">How can I compare String value with ArrayList of String type in Java?</a></li> <li><a href="https://stackoverflow.com/questions/5153496/how-can-i-compare-two-strings-in-java-and-define-which-of-them-is-smaller-than-th">How can I compare two strings in java and define which of them is smaller than the other alphabetically?</a></li> </ul>

2. COThat's because you *add* `count` to the list each time you increment it. Either just print `count` instead of `list`, or remove the previous `count` from `list` before you add it again.

Guidance

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.
