    <p>For such a thing you should in all cases try to have unified constructor parameters or a way to store the parameters per class.</p> <p>Now for your questions. <code>Class&lt;?&gt;</code> is a reference to a unknown class. Basically to any class. When using it its more or less equal to <code>Class&lt;Object&gt;</code> because all classes got <code>Object</code> as parent.</p> <p>For using constructors with multiple arguments you first need to fetch the fitting constructor. At this point its already possible to fetch errors that happen in case the class does not support instances with this configuration of arguments. Fetching the constructor works this way:</p> <pre><code>aClass.getConstructor(new Class[]{String.class, Object.class, ...});</code></pre> <p>This works with as many argument types as you like. Creating the new instance of the class then works this way:</p> <pre><code>constructor.newInstance(theString, theObject, ...);</code></pre> <p>The function <code>newInstanace</code> is implemented as many arguments as needed. So depending on how many arguments the constructor that was requested requires the <code>newInstance</code> function will be able to work with it.</p> <p>For all what you intend... maybe a proposal: Maybe its a option not to load the new objects using reflection but rather by storing instances of those objects and returning copies of the objects created using copy constructors or the <code>clone</code> method. In many cases this is less difficult to get running.</p>

    1. COHi actually the class<?> type refers to the return type of the class in my case. eg: value for class<?> type --> Boolean.class

    3. COFor the return type you have to use `Class<?>` because this basically says "any class type". Means a class reference to any class, no limits set. Everything else would require a explicit cast.

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.
