    <p>I want two images from two different classes that extend JPanel to be side by side.</p> <p>The problem that I'm having is that the two JPanels should be inside the JFrame but when I do framename.add(panel) it replaces the other one instead of adding two of them side by side.</p> <p>I have tried adding flowlayout and other layouts inside the main class, but none of the images showed up.</p> <p><strong>So my question is</strong>, if I have two classes that extend Jpanel, how do i add those two panels inside a Jframe so that they'll be side by side (next to each other) without replacing the other panel?</p> <p>Any suggestions would be greatly appreciated.</p> <p><strong>Edit</strong>: If I extend JFrame to a class, does that class automatically become a JPanel itself? I know what extends means, but I'm not sure how it works in regards to a Jframe.</p> <p><strong>Main.java</strong></p> <pre><code>import javax.swing.*; import java.awt.*; import java.net.URL; public class Main { public static void main(String[] args) { JFrame frame = new JFrame(); Panel1 s = new Panel1(); //picture 1 Panel2 n = new Panel2(); //picture 2 frame.add(n); frame.add(s); //here is the problem, it replaces the previous panel f.setSize(200,100); f.setLocation(0,400); f.setVisible(true); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } } </code></pre> <p><strong>Panel1.java</strong></p> <pre><code>import javax.swing.*; import java.awt.*; import java.net.URL; public class image2 extends JPanel { ImageIcon anotherIcon; public image2() //constructor { URL imageURL = Panel1.class.getResource("images/puppy.png"); anotherIcon = new ImageIcon(imageURL); } public void paint(Graphics g) { super.paintComponent(g); anotherIcon.paintIcon(this, g, 0, 0); } } </code></pre> <p><strong>Panel2.java</strong> </p> <pre><code>import javax.swing.*; import java.awt.*; import java.net.URL; public class Panel2 extends JPanel { ImageIcon anotherIcon2; public Panel2() //constructor { URL imageURL = Panel2.class.getResource("images/puppy2.png"); anotherIcon = new ImageIcon(imageURL); } public void paint(Graphics g) { super.paintComponent(g); anotherIcon2.paintIcon(this, g, 0, 0); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
