Java coin toss score problem (score is multiplied instead of incremented)

Question

My score in my JAVA coin toss program is multiplied instead of incremented and i have no idea why it's happening. I also know that i have some redundant code in this thing (ex. buttonsPanel.add(button2); buttonsPanel.add(button); this.add(buttonsPanel); titlePanel.add(titleText); this.add(titlePanel); this.add(player_turn); this.add(playerOneScore); this.add(playerTwoScore); I will solve it after i find the solution to my score problem. )

Here is my code :

` Random random = new Random();

  int player1Score = 0;
    
  int player2Score = 0;


 JPanel buttonsPanel; 
 JButton button;
 JButton button2;

 JPanel titlePanel;
 JLabel titleText;
 JLabel player_turn;
 JLabel playerOneScore;
 JLabel playerTwoScore;

I tried getting help from chat GPT but that thing confused me even more.
