How to create JSplitPane to divide components in Java?

At first, set two components which we will dividing −

JComponent one = new JLabel("Label One"); one.setBorder(BorderFactory.createLineBorder(Color.yellow)); JComponent two = new JLabel("Label Two"); two.setBorder(BorderFactory.createLineBorder(Color.orange));

Now, split it using SplitPane −

Example

package my; import java.awt.BorderLayout; import java.awt.Color; import javax.swing.BorderFactory; import javax.swing.JComponent; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JSplitPane; public class SwingDemo {    public static void main(String[] a) {       JFrame frame = new JFrame();       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       JComponent one = new JLabel("Label One");       one.setBorder(BorderFactory.createLineBorder(Color.yellow));       JComponent two = new JLabel("Label Two");       two.setBorder(BorderFactory.createLineBorder(Color.orange));       JComponent three = new JLabel("Label Three");       three.setBorder(BorderFactory.createLineBorder(Color.blue));       JComponent four = new JLabel("Label Four");       four.setBorder(BorderFactory.createLineBorder(Color.green));       JSplitPane split1 = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT);       split1.setLeftComponent(one);       split1.setRightComponent(two);       JSplitPane split2 = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT);       split2.setLeftComponent(three);       split2.setRightComponent(four);       frame.add(split1, BorderLayout.NORTH);       frame.add(split2, BorderLayout.SOUTH);       frame.setSize(550, 250);       frame.setVisible(true);    } }
