How do you redicrect your Java application to another java file -

here's code:

public class cyptography implements actionlistener {   jframe frame = new jframe("cyptography");    jtextfield input = new jtextfield();   jbutton decrypt = new jbutton("decrypt");   jtextfield output = new jtextfield();   jbutton encrypt = new jbutton("encrypt");   container north = new container();    jradiobutton scytale = new jradiobutton("scytale");   jradiobutton caesarcipher = new jradiobutton("caesar cipher");   jradiobutton vigenerecipher = new jradiobutton("vigenere cipher");   container south = new container();    public cyptography() {     frame = new jframe("cyptography");     frame.setlayout(new borderlayout());     frame.setsize(700,300);      north.setlayout(new gridlayout(1,4));     north.add(decrypt);     north.add(input);     input.addactionlistener(this);     north.add(encrypt);     north.add(output);     output.addactionlistener(this);     frame.add(north, borderlayout.north);      south.setlayout(new gridlayout(1,3));     south.add(scytale);     scytale.addactionlistener(this);     south.add(caesarcipher);     caesarcipher.addactionlistener(this);     south.add(vigenerecipher);     vigenerecipher.addactionlistener(this);     frame.add(south, borderlayout.south);     frame.setdefaultcloseoperation(jframe.exit_on_close);     frame.setvisible(true);   }    public static void main(string[] args) {     new cyptography();   }    @override   public void actionperformed(actionevent event) {     if (event.getsource().equals(scytale)){       //redirects scytale       }     else if (event.getsource().equals(caesarcipher)){       //redirects ceasar cipher      }     else if (event.getsource().equals(vigenerecipher)){       //redirects vigenere cipher     }   }    //decrypt - text has been decoded.   public void decrypt() {    }    //encrypt - convert (information or data) cipher or code, prevent unauthorized access   public void encrypt() {    } } 

these 3 (scytale, caesar cipher, , vigenere cipher) buttons radio buttons. i'm trying get: click onto radio button, want method actionpreformed direct java class. called scytale.java or caesarcipher.java or vigenerecipher.java.
