I don't manage to get a maximized JFrame automatically. I have to do
it manually. After hours of search, I just don't find the way to do
it. Can anyone help me? Where is my fault in the code?

import java.awt.*;
import javax.swing.*;

public class Test
{
        static JFrame venster=new JFrame("Testvenster");
        
        public static void main(String[]args)
        {
                Toolkit tkit=venster.getToolkit();
                Dimension vensterGrootte=tkit.getScreenSize();
                
                int vensterBreedte=vensterGrootte.width;
                int vensterHoogte=vensterGrootte.height;
                int positieBreedte=0;
                int positieHoogte=0;

venster.setBounds(positieBreedte,positieHoogte,vensterBreedte,vensterHoogte);
venster.setExtendedState(JFrame.MAXIMIZED_BOTH);

                venster.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                venster.setVisible(true);
        }
}
