jpasswordfield - Java Program That Reveals Hidden Password -

-

i want make simple java program reveals password copied browser or application hidden in form of asterisks.

i wrote code doesn't work!

when copy password facebook password field example, , paste jpasswordfield on program. , transform normal text, shows me wrong output (in fact, gives me class name weird)

however, when copy normal text , paste jpasswordfield , text, gives correct normal text back!

so why isn't working? i'm sorry if question seems stupid little. i'm new programming , practical programs. how can make work? :d

thanks in advance, here's code:

class passwordviewer extends jframe {     jpasswordfield field = new jpasswordfield(20);     jbutton btn = new jbutton("ok");     jpanel panel = new jpanel();     char[] s;      passwordviewer() {         setsize(300, 300);         panel.add(field);         panel.add(btn);         setdefaultcloseoperation(exit_on_close);         add(panel);          btn.addactionlistener(new actionlistener() {             public void actionperformed(actionevent arg0) {                 s = field.getpassword();                 findpass();             }         });     }     void findpass() {         string str = "";         (int = 0; < s.length; i++) {             str += s[i];         }         joptionpane.showmessagedialog(null, str, "passwordviewer",             joptionpane.information_message);     }     public static void main(string[] args) {         passwordviewer passview = new passwordviewer();         passview.setvisible(true);     } }

apparently, cannot copy browser's password field @ankitkatiyar91 pointed out. mistaken. question meaningless until can find way copy password browser's password field.
