    <p>OK, i need someone to explain to me where to start on this project.</p> <p>First I need to overload the constructor by adding a default (no-args) constructor to <em>Person</em> that defines an object to have the name "N/A" and an id of -1. </p> <p>Then i need to add a setter method named reset that can be used to reset the two private instance variables of this class to two values passed in as parameters. </p> <p>Then I need to add a getter method named getName and getId that can be used to retrieve these two private variables</p> <p>Here is the code:</p> <pre><code>public class Person { private String name; private int id; private static int personCount = 0; // constructor public Person(String pname) { name = pname; personCount++; id = 100 + personCount; } public String toString() { return "name: " + name + " id: " + id + " (Person count: " + personCount + ")"; } // static/class method public static int getCount() { return personCount; } </code></pre> <p>////////////////////////////////////////////////</p> <pre><code>public class StaticTest { public static void main(String args[]) { Person tom = new Person("Tom Jones"); System.out.println("Person.getCount(): " + Person.getCount()); System.out.println(tom); System.out.println(); Person sue = new Person("Susan Top"); System.out.println("Person.getCount(): " + Person.getCount()); System.out.println(sue); System.out.println("sue.getCount(): " + sue.getCount()); System.out.println(); Person fred = new Person("Fred Shoe"); System.out.println("Person.getCount(): " + Person.getCount()); System.out.println(fred); System.out.println(); System.out.println("tom.getCount(): " + tom.getCount()); System.out.println("sue.getCount(): " + sue.getCount()); System.out.println("fred.getCount(): " + fred.getCount()); } } </code></pre> <p>I'm not exactly sure where to start and I don't want just the answer. I'm looking for someone to explain this clearly.</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
