    <p>I'm a relatively new java programmer and I've been tinkering around with this program for the better part of the day now and I'm still stuck; I was hoping that you could help me with this. </p> <p>So the program is supposed to meet the following requirements:</p> <blockquote> <p>Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:</p> <p>1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...</p> <p>By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.</p> </blockquote> <p>This is my code:</p> <pre><code> //Generates Fibonacci sequence while (fibNum &lt; 144) { int lastValue = (Integer) fibList.get(fibList.size()-1); int secondToLastValue = (Integer) fibList.get(fibList.size()-2); fibNum = secondToLastValue + lastValue; if (fibNum &lt; 144) { fibList.add(fibNum); } //Picks out the even numbers from limitFibList for (int i = 0; i &lt; fibList.size(); i++) { if ((Integer) fibList.get(i) % 2 == 0) { evenNumsFibList.add(fibList.get(i)); } } //Sums up the total value of the numbers in the evenNumsFibList for (int i = 0; i &lt; evenNumsFibList.size(); i++) { sum += (Integer) evenNumsFibList.get(i); } </code></pre> <p>...and this is the output that I'm getting:</p> <pre><code>Fibonacci sequence list: [1, 2, 3] Size of the Fibonacci list: 3 Even Numbers list: [2] Total sum of even numbers: 2 Fibonacci sequence list: [1, 2, 3, 5] Size of the Fibonacci list: 4 Even Numbers list: [2, 2] Total sum of even numbers: 6 Fibonacci sequence list: [1, 2, 3, 5, 8] Size of the Fibonacci list: 5 Even Numbers list: [2, 2, 2, 8] Total sum of even numbers: 20 Fibonacci sequence list: [1, 2, 3, 5, 8, 13] Size of the Fibonacci list: 6 Even Numbers list: [2, 2, 2, 8, 2, 8] Total sum of even numbers: 44 Fibonacci sequence list: [1, 2, 3, 5, 8, 13, 21] Size of the Fibonacci list: 7 Even Numbers list: [2, 2, 2, 8, 2, 8, 2, 8] Total sum of even numbers: 78 Fibonacci sequence list: [1, 2, 3, 5, 8, 13, 21, 34] Size of the Fibonacci list: 8 Even Numbers list: [2, 2, 2, 8, 2, 8, 2, 8, 2, 8, 34] Total sum of even numbers: 156 Fibonacci sequence list: [1, 2, 3, 5, 8, 13, 21, 34, 55] Size of the Fibonacci list: 9 Even Numbers list: [2, 2, 2, 8, 2, 8, 2, 8, 2, 8, 34, 2, 8, 34] Total sum of even numbers: 278 Fibonacci sequence list: [1, 2, 3, 5, 8, 13, 21, 34, 55, 89] Size of the Fibonacci list: 10 Even Numbers list: [2, 2, 2, 8, 2, 8, 2, 8, 2, 8, 34, 2, 8, 34, 2, 8, 34] Total sum of even numbers: 444 Fibonacci sequence list: [1, 2, 3, 5, 8, 13, 21, 34, 55, 89] Size of the Fibonacci list: 10 Even Numbers list: [2, 2, 2, 8, 2, 8, 2, 8, 2, 8, 34, 2, 8, 34, 2, 8, 34, 2, 8, 34] Total sum of even numbers: 654 </code></pre> <p>Obviously my while loop is contributing to my problems, but I don't know how to fix it. </p> <p>Would greatly appreciate your help,</p> <p>Haque</p>

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.
