write java code

Assume that you have created a jLabel with the name "employeeName", two jTextFields with the name "firstName_TF" and "lastName_TF", and a jButton with the name "addBtn". You also have a combo box with the name "title_CB" that has "Mr." in the first option and "Mrs." in the second option.

When the button is clicked, get the text iwritten in "firstName_TF" and "lastName_TF". Depending on the selection of the title_CB, display them in the "employeeName" label as follows:

If the title is the first selection

Mr Last name, first name.

If the title is the second selection

Mrs Last name, first name.

Write the code for this button handler.
