How to combine FlowLayout and BoxLayout in Java?\\n

To combine both the layouts, here we have created two panels −

Frame f = new JFrame("Combining Layouts");
JPanel panel1 = new JPanel();
JPanel panel2 = new JPanel();

Now, set the layouts accordingly −

panel1.setLayout(new BoxLayout(panel1, BoxLayout.Y_AXIS));
panel2.setLayout(new FlowLayout());

Then after adding components to both the panels, add them to the frame −

f.add(panel1, BorderLayout.WEST);
f.add(panel2, BorderLayout.CENTER);

Example

package my;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.FlowLayout;
import javax.swing.BoxLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextArea;
public class SwingDemo {
   public static void main(String[] args) {
      JFrame f = new JFrame("Combining Layouts");
      JPanel panel1 = new JPanel();
      panel1.setLayout(new BoxLayout(panel1, BoxLayout.Y_AXIS));
      JPanel panel2 = new JPanel();
      panel2.setLayout(new FlowLayout());
      panel2.setBackground(Color.red);
      panel1.add(new JTextArea("TextArea1"));
      panel1.add(new JTextArea("TextArea2"));
      panel1.add(new JTextArea("TextArea3"));
      panel1.add(new JTextArea("TextArea4"));
      panel1.add(new JTextArea("TextArea5"));
      panel1.add(new JTextArea("TextArea6"));
      panel1.add(new JTextArea("TextArea7"));
      panel2.add(new JLabel("JLabel1"));
      panel2.add(new JLabel("JLabel2"));
      panel2.add(new JLabel("JLabel3"));
      panel2.add(new JLabel("JLabel4"));
      panel2.add(new JLabel("JLabel5"));
      panel2.add(new JLabel("JLabel6"));
      panel2.add(new JLabel("JLabel7"));
      f.add(panel1, BorderLayout.WEST);
      f.add(panel2, BorderLayout.CENTER);
      f.setVisible(true);
      f.setSize(550, 400);
      f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   }
}
