    <p>I have a table that show a Subtitle structure that was sorted in a right order from 1, 2, 3..... TitleID is unique.</p> <pre> TitleID - Title - Level - Order 451 - History - Level1 - 1 123 - History of America - Level2 - 2 465 - History of Cali - Level3 - 3 578 - History of NewYork - Level3 - 4 765 - History of Europe - Level2 - 5 754 - History of West Europe - Level3 - 6 </pre> <p>This table was converted into a <code>List&lt;String[]&gt;</code> of <code>{"451", "History", "Level1", "1" }</code>, <code>{"123", "History of America", "Level2", "2" }</code>... also in a right order.</p> <p>I want to convert this <code>List&lt;String[]&gt;</code> into a <code>HashMap&lt;String, List&lt;String[]&gt;&gt;</code>. If i do it manually it should be like this:</p> <pre><code>HashMap&lt;String, List&lt;String[]&gt;&gt; titleHashMap = new HashMap&lt;String, List&lt;String[]&gt;&gt;(); List&lt;String[]&gt; subTitleList=new ArrayList&lt;String[]&gt;; String[] titles1={"123", "History of America", "Level2"}; subTitleList.add(titles1); String[] titles12={"765", "History of Europe", "Level2"}; subTitleList.add(titles12); titleHashMap.put("451", subTitleList); List&lt;String[]&gt; subTitleList2=new ArrayList&lt;String[]&gt;; String[] titles2={"465", "History of Cali" , "Level3"}; subTitleList2.add(titles2); String[] titles21={"578", "History of NewYork", "Level3"}; subTitleList2.add(titles21); titleHashMap.put("123", subTitleList2); </code></pre> <p>But i don't want to do it manually, so how to do it automatically? Note: I also want a root level that parent of all Level1. Ex, <code>titleHashMap.put("root", subTitleListOfLevel1); </code></p>

    2. COIf the size of the string array: `{"123", "History of America", "Level2"}` is limited reflecting only a number of attribute why aren't you are going with OOP style ?

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.
