    <p>I read the other post and added <a href="https://stackoverflow.com/a/8637983/1068746">a running code of my own</a>. perhaps you should look there. It generates the Triangles and everything. Anyway, this is not a "naming convention" question and would probably get the right feedback if you changed the question to "how to make an instance in java". </p> <p>The complete code I wrote there (if you don't feel like clicking links) is here as well and should fill in any blanks other people left for you to fill in : </p> <pre><code>import java.io.BufferedReader; import java.io.File; import java.io.FileReader; import java.io.IOException; import java.util.Arrays; import java.util.HashSet; import java.util.Set; public class Triangle { private int[]sides; public Triangle( int x, int y, int z) { sides = new int[]{x,y,z}; Arrays.sort( sides ); } public Triangle( String ... args ) { this( Integer.parseInt( args[0].trim() ), Integer.parseInt( args[1].trim() ), Integer.parseInt( args[2].trim() )); } @Override public boolean equals( Object o ) { if ( this == o ) return true; if ( o == null || getClass() != o.getClass() ) return false; Triangle triangle = ( Triangle ) o; if ( !Arrays.equals( sides, triangle.sides ) ) return false; return true; } @Override public int hashCode() { return sides != null ? Arrays.hashCode( sides ) : 0; } @Override public String toString() { return "Triangle{" + "sides=" + Arrays.toString( sides ) + '}'; } public static void main( String[] args ) throws IOException { String[] input = new String[]{ "1,2,1" , "1,1,2", "1,2,3","1,3,1","1,1,1","1,3,3","1,1,3"}; Set&lt;Triangle&gt; triangles = new HashSet&lt;Triangle&gt;( ); for ( String s : input ) { triangles.add( new Triangle( s.split( "," ) ) ); } System.out.println( "triangles = " + triangles ); } } </code></pre>

    1. COYou clearly do not understand this site. The people who ask questions here do not have to be Java developers. I absolutely feel your insult in that sense is out of line, too. I also do not appreciate you giving the "answer" (which is, wrong by the way). Lead users to the answer, don't give it to them.

    2. COI am truely sorry, I didn't mean it that way. While reading other answers I got the feeling they were giving too little code and leaving out too many blanks under the assumption they will be filled. I simply tried to emphasize the fact I do not assume that. I never said it is wrong to not be a Java developer, and most definitely had no intention to insult anyone. I removed the line you commented on and would gladly remove any other text that might be insulting. I successfully ran my code, and would be glad to help if someone failed to do the same.

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.
