<h2><a href="https://docs.oracle.com/javase/7/docs/api/java/util/AbstractMap.SimpleEntry.html" rel="noreferrer">AbstractMap.SimpleEntry</a></h2> Easy you are looking for this: <pre><code>java.util.List<java.util.Map.Entry<String,Integer>> pairList= new java.util.ArrayList<>(); </code></pre> How can you fill it? <pre><code>java.util.Map.Entry<String,Integer> pair1=new java.util.AbstractMap.SimpleEntry<>("Not Unique key1",1); java.util.Map.Entry<String,Integer> pair2=new java.util.AbstractMap.SimpleEntry<>("Not Unique key2",2); pairList.add(pair1); pairList.add(pair2); </code></pre> This simplifies to: <pre><code>Entry<String,Integer> pair1=new SimpleEntry<>("Not Unique key1",1); Entry<String,Integer> pair2=new SimpleEntry<>("Not Unique key2",2); pairList.add(pair1); pairList.add(pair2); </code></pre> And, with the help of a <code>createEntry</code> method, can further reduce the verbosity to: <pre><code>pairList.add(createEntry("Not Unique key1", 1)); pairList.add(createEntry("Not Unique key2", 2)); </code></pre> Since <code>ArrayList</code> isn't final, it can be subclassed to expose an <code>of</code> method (and the aforementioned <code>createEntry</code> method), resulting in the syntactically terse: <pre><code>TupleList<java.util.Map.Entry<String,Integer>> pair = new TupleList<>(); pair.of("Not Unique key1", 1); pair.of("Not Unique key2", 2); </code></pre>

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.
