Dear Ian Smith,
I try your solution and it works! The main issue in my code is:
//Incorrect code
MyRobot myrobot = new MyRobot();
//Correct code
Robot myrobot = new Robot();

Thanks for the advise on finding "new Result". I didn't aware that what I'm doing actually is initialize another Result object rather that manipulated on existing method. Now I finally know the problem is locate on MySurvey.java line 48. Need change from result.printRep ort(); to centerPanel.get Result().printR eport();
Jos thank you very much....Leave a comment:
