and now I would like to add "Action" for my jComboBox. If I will press for example "First" from my ComboBox on my textArea will appears "First" (yes "First", and I will press "Next" on my textArea should appear "Next" - same text as was in jComboBox)

And I made something like:

Anyone can help me how can i do it?

You can get the selected item (hint) or the selected index (hint) from the combo box. Once you have the index you can get the item at the selected index (hint)
Check the API for methods which will let you do this.
Once you have the item, well you have the required string!

You've been given the link to the Swing tutorial multiple times and asked to read the relevant section. The combo box tutorial shows you how to use listeners.

You've also been asked to post a SSCCE when you encounter problems after reading the tutorial.

You have done neither, therefore I don't feel any need to waste my time and repeat information that is found in the tutorial and API.

Ok it works now. It was wrong because Object matim was final.

Everything is ok now.

I agree. Here's the link:
