Body
I am trying to write a class with all the methods I need for my main, but am having trouble figuring out how to ascertain the desired values using the methods. The ones I am having trouble with are getAverageLength and getCount. Current Output: <pre><code>The length of Line 1 is 1.0 The length of Line 2 is 10.0 There are 0 lines and the average length is 0 The length of Line 1 is 1.0 The length of Line 2 is 10.0 The length of Line 3 is 7.0 There are 0 lines and the average length is 0 </code></pre> Expected Output: <pre><code>The length of Line 1 is 1 The length of Line 2 is 10 There are 2 lines and the average length is 5.5 The length of Line 1 is 7 The length of Line 2 is 10 The length of Line 3 is 7 There are 3 lines and the average length is 8.0 </code></pre> This is the portion of my main method that I am using. <pre><code>public class TestParts { public static void main(String[] args) { MyLine ml1 = new MyLine(); MyLine ml2 = new MyLine(10); System.out.println("The length of Line 1 is " + ml1.getLength()); System.out.println("The length of Line 2 is " + ml2.getLength()); System.out.println("There are " + MyLine.getCount() + " lines and the average length is " + MyLine.getAverageLength()); MyLine ml3 = new MyLine(7); ml1.setLength(7); System.out.println("The length of Line 1 is " + ml1.getLength()); System.out.println("The length of Line 2 is " + ml2.getLength()); System.out.println("The length of Line 3 is " + ml3.getLength()); System.out.println("There are " + MyLine.getCount() + " lines and the average length is " + MyLine.getAverageLength()); } } </code></pre> And the following is the seperate class that I am writing to calculate the values. <pre><code>class MyLine { private double getLength; MyLine() { getLength = 1; } double getLength() { return getLength; } MyLine(double setLength) { getLength = setLength; } public void setLength(int i) { getLength = getLength(); } public static int getCount() { return 0; } public static int getAverageLength() { return 0; } } </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.
