I have to select and check on the radio button of the initial JTable, and found the radio button but I am not

My code is:

Check out the setSelected method.

Note that calling setSelected(false) will not uncheck a radio button. To do that, the usual trick is to add a radio button to the same button group but not add it to the user interface. When you select this invisible radio button all other radio buttons are unselected.

Cool, this method was really needed. I didn't know they added it in Java 6.

I only came to Java after 6 was released, so it's maybe easier for me ;)

There are 4072 (I think) classes in Java7, and some have hundreds of methods, so you can’t expect people to know about every method.

But how to specify the selected row in the setSelected is something like:
