    <p>This is homework. </p> <p>GOAL: I want to compare the date of two objects to decide whether my person object is an adult or not and store this in a string. </p> <p>The strange thing is, all my values of date d1 are 0; </p> <pre><code>public class Date { public int day, month, year; public String child Date(date d1, date d2) { if ((d1.year - d2.year &gt; 18) || ((d1.year - d2.year == 18) &amp;&amp; (d2.year&gt; d1.year)) || ((d1.year - d2.year == 18) &amp;&amp; (d2.year == d1.maand) &amp;&amp; (d2.day &gt; d1.day))) { child = adult; } else { child = child; } Date(int a, int b, int c) { a = year; b = month; c = day; } Date (String birthdate) { String pattern = "\\d{2}-\\d{2}-\\d{4}"; boolean b = birthdate.matches(pattern); if (b) { String[] str = birthdate.split("-"); for (String s: str) this.day = Integer.parseInt(str[0]); this.month = Integer.parseInt(str[1]); this.year = Integer.parseInt(str[2]); this.child = false; } else { System.out.println("Wrong format"); } } </code></pre> <p>When I make a test, this happens: </p> <blockquote> <pre><code> System.out.println("D1 year = " + d1.year); System.out.println("D1 day = " + d1.day); System.out.println("D1 month = " + d1.month); </code></pre> </blockquote> <pre><code>Result: D1 year = 0 D1 day = 0 D1 month = 0 </code></pre> <p>Why does this happen? Lets look at my other class. </p> <p>My other class, where my method infoPerson is located is as following: </p> <pre><code> public static Person infoPerson() { String name, lastname, birthdate; Datum birthday, today; System.out.println("Firstname:"); name = userInput(); System.out.println("Lastname:"); lastname = userInput(); System.out.println("Birthdate?:"); birthdate = userInput(); //here I send the string birthdate to my Date class birthday = new Date(birthdate); today = new Date(3, 7, 2013); //Here I want to compare my two Date objects, today and birthday. This is were I got stuck, how do I do this correctly? dateChild = new Date(today, birthday); // here i send the new date to my Person class what consists of two strings and Data birthday return new Gast(name, lastname, dateChild); } </code></pre>

    1. COHow come this: `void compareTo(date d1, date d2)` works ?

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.
