How to change the values of spinner and radio button if I click on a row from jtable (must depend on the values form jtable)
Question
If I click a row(JTABLE), it must display the specific values back to the textfields/combobox/radiobutton/spinner. But in my case, it's just hard to retrieve the values back to the RADIO BUTTON and SPINNER.

How to change the values of spinner and radio button
- The spinner should be easily settable by calling its
setValue(...)method, and passing in the number from the selected table row item. - For the JRadioButtons, probably the easiest solution is to use a Map that maps the selection to its radio button, and then using this map to get a reference to the proper JRadioButton, and calling
setSelected(true)on it.
For an example, and for an example of a Minimal, Complete, and Verifiable example , please have a look at:
import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.event.ActionEvent;
