JFrame with JSplitpane

Sure, I can help you with that! Here is an example code snippet for creating a JFrame with JSplitPane:

import javax.swing.*;

public class MyFrame extends JFrame {
  
  public MyFrame() {
    // Set JFrame properties
    setTitle("JFrame with JSplitPane");
    setSize(500, 500);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    // Create JSplitPane
    JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT);
    splitPane.setDividerLocation(250);
    splitPane.setResizeWeight(0.5);

    // Add components to JSplitPane
    JPanel leftPanel = new JPanel();
    JPanel rightPanel = new JPanel();
    splitPane.setLeftComponent(leftPanel);
    splitPane.setRightComponent(rightPanel);

    // Add JSplitPane to JFrame
    add(splitPane);
    
    // Display JFrame
    setVisible(true);
  }
  
  public static void main(String[] args) {
    new MyFrame();
  }
}

This code creates a horizontal `JSplitPane` with two `JPanel` components and adds it to a `JFrame`. You can adjust the `setDividerLocation` and `setResizeWeight` methods to customize the appearance of the `JSplitPane`. Let me know if you have any further questions!
