2D-Grafik Was ruft die Paint - Methode auf ?

[Feeder]

Hey Leute ich bin auf etwas eigenartiges gestoßen. Mein JPanel Konstruktor verweist nicht auf die paint - methode. Wer ruft sie also auf.

package game2D;

import java.awt.Component;
import java.awt.Dimension;
import javax.swing.JFrame;


public class Game extends javax.swing.JFrame {

    public Game() {
        setResizable(false);
        initComponents();
    }

    @SuppressWarnings("unchecked")
    // <editor-fold defaultstate="collapsed" desc="Generated Code">                          
    private void initComponents() {

        jButton1 = new javax.swing.JButton();
        jButton2 = new javax.swing.JButton();
        jButton3 = new javax.swing.JButton();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        setTitle("Spiel");

        jButton1.setText("Credits");
        jButton1.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton1ActionPerformed(evt);
            }
        });

        jButton2.setText("Start");
        jButton2.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton2ActionPerformed(evt);
            }
        });

        jButton3.setText("Ende");
        jButton3.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton3ActionPerformed(evt);
            }
        });

        javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
        getContentPane().setLayout(layout);
        layout.setHorizontalGroup(
            layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(layout.createSequentialGroup()
                .addGap(46, 46, 46)

Wie kann ich dir ein Danke geben. Meine Annotation hat gefehlt 😀. War der compiler zwar nicht zickig hat also trotz der Unsauberkeit geklappt 😀
