I hope what you are trying to achieve is like this. For this please use Box layout.

package com.kcing.kailas.sample.client;  import javax.swing.BoxLayout; import javax.swing.JCheckBox; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.SwingUtilities; import javax.swing.UIManager; import javax.swing.WindowConstants;  public class Testing extends JFrame {      private JPanel jContentPane = null;      public Testing() {         super();         initialize();     }      private void initialize() {         this.setSize(300, 200);         this.setContentPane(getJContentPane());         this.setTitle("JFrame");     }      private JPanel getJContentPane() {         if (jContentPane == null) {             jContentPane = new JPanel();             jContentPane.setLayout(null);              JPanel panel = new JPanel();              panel.setBounds(61, 11, 81, 140);             panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));             jContentPane.add(panel);              JCheckBox c1 = new JCheckBox("Check1");             panel.add(c1);             c1 = new JCheckBox("Check2");             panel.add(c1);             c1 = new JCheckBox("Check3");             panel.add(c1);             c1 = new JCheckBox("Check4");             panel.add(c1);         }         return jContentPane;     }      public static void main(String[] args) throws Exception {         Testing frame = new Testing();         frame.setVisible(true);         frame.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);     } }

I used a BoxLayout and set its second parameter as BoxLayout.Y_AXIS and it worked for me:

panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
