    <p>I have 2 class diagrams, class Address</p> <pre><code>+forename +surename +street +houseno +code +state +toString </code></pre> <p>second Addressbook</p> <pre><code>insert(address: Address) toString() searchSurename (surename: string): Address[*] +searchForename(forename: string): Address[*] </code></pre> <p>i implemented address:</p> <pre><code>public class Address { public static String forename; public static String surename; public static String street; public static int houseno; public static int code; public static String state; public String toString(){ return this.forename + this.surename + this.street + this.houseno + this.code + this.state; } </code></pre> <p>How can I implement Addressbook as easy as possible?</p> <p>EDIT:</p> <pre><code>public class addressbook{ private static ArrayList&lt;Address&gt; book; public addressbook(){ book = new ArrayList&lt;Address&gt;(); } </code></pre> <p>}</p> <p>EDIT QUESTION:</p> <p>Am I allowed to add new methods or attributes in a implementation outside the ones that we use in our class diagrams? </p> <p>EDIT 2:</p> <p>First try implementing method searchSurename with an ArrayList:</p> <pre><code>public static String searchSurename(String surename){ boolean exist = false; if(this.addresses.isEmpty()){ return null; } for(int i=0;i&lt;this.addresses.size();i++) { if(this.addresses.get(i).getSurename() == surename) { exist=true; break; } if(exist) { return this.addresses.get(surename); } else { return this.addresses.get(surename); } } // return ?!? } </code></pre> <p>The Program give me Errors at "this" at any line, maybe a mistake but I cant tell! It Looks a Little bit too difficult, I don't find any implementations where searching through a list is simple.</p>

    3. COSome issues here, first, always try to specify the type of the fields, even if they are easy to find `+name:String`, second that all static members should be underlined. the next thing is address class `toString()` method, it's very bad designed, this is really unlogical to have an instance for showing static members. next, don't think si-sharp, in java we don't have string, it's `String`, the next thing is about arrays, there is no difference between `Address[*]` and `Address[]`.

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.
