Snake game errors - play again button error

I am new to java and I am making a snake game. I worked on it step by step and I reached adding the play again button and start button. I started with the play again and I keep getting errors on line:183 in the gameover method . I wish if someone can explain to me why I keep getting them and what is a possible way to solve it. I have some comments so it can help understand why I have those lines. Thank you in advance!

edit 1: line 183 is if(event.getSource()==replayButton){ the error says ';' expected on the first paranthesis (

edit 2: This is the smallest amount of code possible. I am trying to add a play again button in the gameover method. (I have the high score printed and game over printed, I am trying to add a button and if it is pressed, I wan the game to reset but still have the same score of last times)
