    <p>I have a list of arrays that i want to update, but it gives "index out of bounds" error. I can't seem to find the error. Need a pair of fresh eyes.</p> <pre><code>Global.variables.add(new String[]{(String) jComboBox1.getSelectedItem(), jTextField2.getText(), jTextField3.getText(), (String) jComboBox2.getSelectedItem(), "Reservado"}); public void generateRandom() { for (int i = 0; i &lt; Global.variables.size()-1; i++) { System.out.println("Searching "+Global.variables.get(i)[0]+" in temp "+i); for (int j = 0; j &lt; temp.size()-1; j++) { System.out.println("Testing "+Global.variables.get(i)[0]+" with "+temp.get(j)+" "+j); if (Global.variables.get(i)[0].equals(temp.get(j))) { System.out.println("FOUND!"); Global.variables.get(i)[4] = String.valueOf(Double.parseDouble(Global.variables.get(i)[1]) + mt.nextGaussian() * Double.parseDouble(Global.variables.get(i)[2])); System.out.println(Global.variables.get(i)[0]+" = "+Global.variables.get(i)[4]); } } } } </code></pre> <p>Global.variables contain (name, median, std, distribution, "reserved"); temp contains the name of some variables. So I try to run through the variables list see if they are in <em>temp</em> and update the "reserved" field...however: It gives me error: </p> <pre><code>Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 4 </code></pre> <p>Probably something easy but i can't seem to find what it is.</p> <p><strong>Solved</strong>: I was initializing Global.variables on another place, so some variables actually have the 5th element but others don't. Thanks :)</p>

    1. CONo [SSCCE](http://sscce.org/) (specifically the self-contained part) always makes it more difficult to help. Try `System.out.println(Arrays.toString(Global.variables.get(i)));` just before the line throwing the exception. This may give some insight into the problem.

    3. COYou have 4 elements? And you are accessing the 4th element by putting 4?

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.
