paintComponent is stressing me out; Hangman programming project

I have a programming project implementing the Hangman game. I can only paint certain parts of the hangman at a time, which is dependent on the amount of incorrect tries by the user. The teacher of my programming class requires the creation of the hangman drawing to be in a different class.

The problem I'm having is sending over the number of incorrect tries to a class with the paintComponent.

if(updatedChallenge == challenge)
    {
        incorrectTries += 1;
    }
    challenge = updatedChallenge;

The challenge == updatedChallenge refers to the hidden word before the user's guess and the hidden word after the user's guess. If they are still equal that means the user made an incorrect choice. 1 gets added to the total number of incorrect tries.

Here is my other class:

class HangmanPicture extends JPanel
{
    public void paintComponent(Graphics g)
    {
        super.paintComponent(g);

        g.setColor(Color.BLACK);
        g.drawLine(250, 300, 300, 300); //Platform

        g.drawLine(275, 300, 275, 200); //Pole

        g.setColor(Color.YELLOW);
        g.drawLine(275, 200, 350, 200); //Rope

        g.drawLine(350, 200, 350, 225); //Noose

        g.setColor(Color.CYAN);
        g.drawOval(350, 225, 15, 15); //Head

        g.drawLine(350, 230, 350, 260); //Torso

        g.drawLine(350, 240, 340, 230); //Left Arm

        g.drawLine(350, 240, 360, 230); // Right Arm

        g.drawLine(350, 260, 330, 280); // Left Leg

        g.drawLine(350, 260, 390, 280); // Right Leg
    }
}

I want to put an if statement where each body part gets added after each incorrect try, which requires me to send the number of incorrect tries to the class. Whenever I try to send the number, it always somehow interferes with paintComponent.

Since you are extending the JPanel class, we can add extra methods and fields to the class and use them where HangmanPicture is being used.

HangmanPicture panel = new HangmanPicture();
  ...
  if(updatedChallenge == challenge)
  {
      panel.addIncorrectAttempt();
  }
  challenge = updatedChallenge; 


class HangmanPicture extends JPanel
{
    private int incorrectAttempts = 0;

    // Add one to counter
    public void addIncorrectAttempt(){
      incorrectAttempte++;
    }

    // Get how many times the player entered an incorrect number
    public int getIncorrectAttempts(){
      return incorrectAttempts;
    }
    public void paintComponent(Graphics g)
    {
        super.paintComponent(g);

        g.setColor(Color.BLACK);
        if( incorrectAttempts >= 1 ){
          g.drawLine(250, 300, 300, 300); //Platform
        }

        if( incorrectAttempts >= 2 ){
          g.drawLine(275, 300, 275, 200); //Pole
        }
    }
}
