Going thru code multiple times.

Question

I have 50 years experience a procedural programmer & about 3 years as an OO programmer using Java so my Java Code is not what I would like it to be.
A menu Class named Menu invokes a class named Jobs which in turn Invokes a class named KeyPhrases.
The KeyPhrases class tests which buttons are pressed to decide what to do. For some reason this logic is gone thru the number of times the class Jobs is selected from the class Menu.
Menu code
( Class.forName(sceenButtonClassNames[buttonNumber]).newInstance()).startup( args);Jobs Code
public class Jobs
     public String startup( Args theArgs)
        if (ujPresent)
             jobs.clear();
        else
             uj = new Jobs(true);
     ujPresent = true;
         uj.c400_processExistingJob();
    private void        c400_processExistingJob()
          KeyPhrases.main(job, null,null, DSNPrefix, "Change");
    }KeyPhrases
public class KeyPhrases extends JPanel implements ActionListener, PersonalDataConstants, FileAndClassNames
public void actionPerformed(ActionEvent e)
     Object source = e.getSource();
     String paramString =  e.paramString();
     if (b300_NewTransation(paramString))     
          b200_WriteTransation(paramString);
          b400_ProcessButtons(source);
private void b400_ProcessButtons(Object theSource)
     Object source = theSource;
     if (source == buttonAdd)
    else if (source == buttonDelete)
   else if (source == buttonDone)
    }the b400_.... code is what is gone thru multiple times depending upon the number of times Jobs is chosen from Menu
Feel free to insult my knowledge of Java but please leave some suggestions.

Answer 1

Here is my first attempt at the SSCCE.
1. All the code is in a package named menu.
2. The code consists of;
a. An Interface named DontKnow.
b. A class named MenuButton.
c. A class named Menu containing a main method. This class also contains 13 subclasses which Menu transfers to.
d. These subclasses may have to be standalone classes to get a real test.
3. To stop the test click the red button ( This was written on a Mac.)
