class - How do I use the outcome of my actionPerformed method to effect the main method - java -

i have class called screen containing actionperformed method. want different outcome different menu items: random, aggressive , human.

this outcome effects main method, unsure how link two...

public class screen extends jframe                 implements actionlistener {  actionlistener listener;  jmenuitem random = new jmenuitem("random"); jmenuitem aggressive = new jmenuitem("aggressive"); jmenuitem human = new jmenuitem("human");  public screen(board board){    //menubar items   menu.add(random);     random.addactionlistener(this);     menu.add(aggressive);     aggressive.addactionlistener(this);     menu.add(human);     human.addactionlistener(this);    ....   //sets board of buttons , adds actionlistener each.   .... } public void actionperformed(actionevent e) {        if(e.getsource() == random){        }       if(e.getsource() == aggressive){        }       if(e.getsource() == human){        }     //code board buttons - nothing menu.      //but thought might     if (numclicks == 0){         jbutton piece = (jbutton) e.getsource();         string xy = piece.getname();         string x = xy.substring(0,1);         string y = xy.substring(2,3);         fromxint = integer.parseint(x);         fromyint = integer.parseint(y);          system.out.println("from" + " " +fromxint + "," + fromyint);     }     else{         jbutton piece = (jbutton) e.getsource();         string xy = piece.getname();         string x = xy.substring(0,1);         string y = xy.substring(2,3);         toxint = integer.parseint(x);         toyint = integer.parseint(y);            system.out.println("to" + " " + toxint + "," + toyint);     }     numclicks++;     if (numclicks >= 2){         numclicks = 0;           }     return; } } 

my class contains main method:

public class chess{    public static void main(string [ ] args){      screen s = new screen(board);      // attempt doesn't work     if (s.actionperformed(e) == random){       ..... 

note: new java , still trying head round linking of multiple classes. --------------------the actionperformed method contains events if buttons clicked haven't added code in because on complicates things.--

this approach uses public enum , sets style variable according users menu choice:

package chess; //... public class screen extends jframe         implements actionlistener {      private jmenuitem random = new jmenuitem("random");     private jmenuitem aggressive = new jmenuitem("aggressive");     private jmenuitem human = new jmenuitem("human");      public enum playstyle {random, aggressive, human};     private playstyle style;      public screen(board board) {          //menubar items         menu.add(random);         random.addactionlistener(this);         menu.add(aggressive);         aggressive.addactionlistener(this);         menu.add(human);         human.addactionlistener(this);         //....         //sets board of buttons , adds actionlistener each.       }      @override     public void actionperformed(actionevent e) {         if (e.getsource() == random) {             style=playstyle.random;         }         if (e.getsource() == aggressive) {             style=playstyle.aggressive;         }         if (e.getsource() == human) {             style=playstyle.human;         }          //code board buttons - nothing menu.          //....     }     public playstyle getstyle(){         return style;     }  } 

this class contains main method:

package chess;  import chess.screen.playstyle;  public class chess{       public static void main(string [ ] args){          screen s = new screen(board);           // attempt work          if (s.getstyle()==playstyle.random) {              ...          } else if (s.getstyle()==playstyle.aggressive){              ...
