Body
Your meetsCriteria() method seems a little bit complicated and misses a lot of combination of criteria that are specified or not. Since you have 4 parameters and each parameter can be specified or not, you have 16 (2^4) possible different cases. Obviously, you code doesn't contain that many. The number of possible cases doubles for each field you add to this Restaurant class. You must find a way to avoid this combinatory explosion by making sure that you only need to add one test for each field. Can I suggest you try this way: <pre><code>public class Restaurant { private String _name; private String _address; private String _phoneNum; private Area _area; public boolean meetsCriteria(String name, String area, String phone, String category) { if ( !name.equals("") && !name.equals(this._name) && this._name.indexOf(name) < 0){ // name has been specified and does not match return false; } if(!areas.equals("") && this._aread.getArea().equals(area)){ // area has been specified and does not match return false; } // ... snip ... // do the same kind of thing for phone and category // ... snip ... // At this point, all the criteria that have been specified by the user match, // and all the criteria that haven't been specified have been ignored. return true; } } </code></pre> You can probably do all that in one huge if() statement, but that would probably not be very readable. Or even better, you can extract the matching logic for each of your fields to their own method, like so: <pre><code>public class Restaurant { private String _name; private String _address; private String _phoneNum; private Area _area; public boolean meetsCriteria(String name, String area, String phone, String category) { return matchesName(name) && matchesArea(area) && matchedPhone(phone) && matchesCategory(category); } private boolean matchesName(String name){ return name.equals("") || name.equals(this._name) || this._name.indexOf(name) >= 0; } private boolean matchesArea(String area) { return areas.equals("") || this._aread.getArea().equals(area); } // create the missing methods yourself. } </code></pre>

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.
