    <p>I have created a java method which extracts information from a text file, then adds it to a JTable. However, i want to remove the JTable from the loop as it loops a new table three times. I am having an issue doing this. </p> <p>The code i want to remove out of the loop is displayed is:</p> <pre><code> JTable table = new JTable(myVector,columnNames) {{ setOpaque(false); setDefaultRenderer(Object.class, new DefaultTableCellRenderer() {{ setOpaque(true); }}); }}; JScrollPane scrollPane = new JScrollPane(table); frame.add(new JScrollPane(table) {{ setOpaque(false); getViewport().setOpaque(false); } @Override protected void paintComponent(Graphics g) { g.drawImage(image, 0, 0, this); super.paintComponent(g); } }); </code></pre> <p>This is the full java method:</p> <pre><code> Vector&lt;Vector&lt;String&gt;&gt; myVector = new Vector&lt;Vector&lt;String&gt;&gt;(); FileReader fReader = new FileReader("playerscores.txt"); BufferedReader inFile = new BufferedReader(fReader); String input; String[] temp; while((input=inFile.readLine())!=null) { Vector&lt;String&gt; v = new Vector&lt;String&gt;(); temp = input.split(",",6); for(int i=0;i&lt;temp.length;i++){ v.add(temp[i]); System.out.println(temp[i]+" added"); } System.out.println("V is "+v); myVector.add(v); System.out.println("End of Line"); Vector&lt;String&gt; columnNames = new Vector&lt;String&gt;(); columnNames.addElement("Player Name:"); columnNames.addElement("Score:"); JTable table = new JTable(myVector,columnNames) {{ setOpaque(false); setDefaultRenderer(Object.class, new DefaultTableCellRenderer() {{ setOpaque(true); }}); }}; JScrollPane scrollPane = new JScrollPane(table); frame.add(new JScrollPane(table) {{ setOpaque(false); getViewport().setOpaque(false); } @Override protected void paintComponent(Graphics g) { g.drawImage(image, 0, 0, this); super.paintComponent(g); } }); } </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.
