Java GridLayout - 2 columns

[Lylio]

Hi everyone,

I'm trying to create a basic GUI for booking classes in a gym. I'm not very familiar with the grid layout and struggling with creating a 2 column grid.


Here's what I'm trying to achieve:

And here's my grid code so far:

private void createPanel() {
 
    setLayout(new GridLayout(4, 1));
 
    JPanel panel1 = new JPanel();
    JPanel panel2 = new JPanel();
    JPanel panel3 = new JPanel();
    JPanel panel4 = new JPanel();
 
    //Panel 1: member ID field
    panel1.add(memberIDLabel);
    panel1.add(memberIDField);
 
    panel1.add(courseNameLabel);
    panel1.add(courseNameField);
 
    panel1.add(bookButton);
 
    //Panel 4: 'view courses' and 'view members' buttons
    panel4.add(coursesButton);
    panel4.add(bookingsButton);
 
    //Attaches panels to frame
    this.add(panel1);
    this.add(panel2);
    this.add(panel3);
    this.add(panel4);
}

Any help would be much appreciated. Many thanks.
