Question about creating Jtable from a "Self Made" object.

Question

Hi all,
I am new to java and this is my first post here.
First of all, i want to say nice to meet u all. This is a blessed forum, and it already helped me a lot.
I hope that i will be clear with my question.
Now to the question:
I have created a class that reads parameter file and its meta file and combine them (each parameter in the file gets its properties such as "Mask", "Default" and else from the meta file) to one object (the class creates collection of instance of it self that has a get method.
the class also has method that get "Column Names" from the instance.
I want to create a Jtable that will present these parameter(each row will present 1 parameter).
Only the second column should be editble and it should choose the editor by the type of data (example: if it is boolean should get a check box, i has more than one "ValidValue" should get a combo box and so on).
What would be the best way to do that?
I am not looking for a source code, I am looking for concept suggestion.
This project is for "Self Learning" porpuse, and any help will be gratitude.
Thanks a lot you all,
On Katalan.

Use the Adapter pattern (http://en.wikipedia.org/wiki/Adapter_pattern) to wrap your object as a TableModel.
eg, if your data class is "ParameterSet" you might do this...
public class ParameterSetTableModel implements TableModel
    private final ParameterSet set;
    public ParameterSetTableModel(ParameterSet set)
        this.set = set;
    public String[] getColumnNames()
        return this.set.getColumnNames();
    // you'll need to implement all TableModel methods, either
    // directly calling the wrapped object or calling it and
    // converting the data, or whatever's appropriate
}
