    Default Trouble getting my frame and panels to show up!?!?

    I'm trying to add these two panels to my frame. I want my mainPanel1 to be in the top of my frame and mainPanel2 to be in the bottom. Therefore I thought I'm suppose to set layout to border layout like a did. A frame does display on my screen but there is nothing in it. I tried creating a border line and title thinking that I needed to make the panels visible some way but it's still not working. However, it seems to compile fine without any errors. Any ideas?
    import javax.swing.*;
    import java.awt.*;
    import javax.swing.border.Border;
    import javax.swing.border.LineBorder;
    import javax.swing.border.TitledBorder;
     
    public class resistortests extends javax.swing.JFrame
    {
     
        public resistortests()
        {
     
            JPanel mainPanel1 = new JPanel(new BorderLayout());
            //mainPanel1.setLayout(new BorderLayout());
            mainPanel1.setBorder(new TitledBorder("mainPanel1"));
     
            JPanel mainPanel2 = new JPanel(new GridLayout());
            //mainPanel2.setLayout(new GridLayout(0,5));
            mainPanel2.setBorder(new TitledBorder("mainPanel2"));
     
            Font largeFont = new Font("TimesRoman", Font.BOLD, 20);
            Border lineBorder = new LineBorder(Color.BLACK,2);
     
            setLayout(new BorderLayout(0,5));
     
            add(mainPanel1, BorderLayout.NORTH);
            add(mainPanel2, BorderLayout.SOUTH);
     
     
        }
     
        public static void main(String args[])
        {
            JFrame resFrame = new JFrame("Resistor Lookup");
            resFrame.setSize(500, 500);
            resFrame.setLocationRelativeTo(null);
            resFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            resFrame.setVisible(true);
        }
     
    }

    You want 'resFrame' to be resistortests object:

    resistortests resFrame = new resistortests();

    Then set the name of the frame in the resistortests() constructor. You should also respect Java naming conventions and name your classes with Capital letters, appropriately camel-cased after that, so maybe "ResistorTests."

    Nevermind I figured it out. I didn't create a instance of my object resistortests() in main.

    Also I did a set layout to grid which didn't shrink the panels down in the North and South portions of the frame. Looking much nicer now.
