I want my button not in the same row as my choose buttons in my gui? How will I do that?

Time:12-15

How do I add a break to put my "Make pokemon" buttons and textarea not in the same row as my "Pokemon choice." I'm trying to put an empty JLabel, but I don't think it works.

public class PokemonPanel extends JPanel {

 private JLabel lTitle = new JLabel("Pokemon");
 private JLabel lMsg = new JLabel("                ");
   private JButton bDone = new JButton(" Make Pokemon ");
   private JButton bClear = new JButton(" Clear ");

   private JPanel topSubPanel = new JPanel();
   private JPanel centerSubPanel = new JPanel();
   private JPanel bottomSubPanel = new JPanel();
   private GUIListener listener = new GUIListener();
   private Choice chSpe = new Choice();
   private JLabel lEmp = new JLabel("                ");
   private PokemonGUILizylf st;
   private final int capacity = 10;
   private PokemonGUILizylf[ ] stArr = new     PokemonGUILizylf[capacity];
   private int count = 0;
   private String sOut = new String("");
   private JTextArea textArea = new JTextArea(400, 500);
  private JTextArea textArea2 = new JTextArea(400, 500);


   private JScrollPane scroll = new JScrollPane(textArea,JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
   JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);


   public PokemonPanel() {

  this.setLayout(new BorderLayout()); 
  this.setPreferredSize(new Dimension(400, 500));
  topSubPanel.setBackground(Color.cyan); 
  centerSubPanel.setBackground(Color.white); 
  bottomSubPanel.setBackground(Color.white); 
 
  topSubPanel.add(lTitle);
  this.add("North", topSubPanel); 

  JLabel lSpe = new JLabel("Pokemon Available: ");
  JLabel lEmp = new JLabel("         ");
  JLabel lNew = new JLabel("New Pokemon: ");

 //add choices to the choice dropdown list
  chSpe.add("Choose");
  chSpe.add("Bulbasaur");
  chSpe.add("Venusaur");
  chSpe.add("Ivysaur");
  chSpe.add("Squirtle");
  chSpe.add("Wartortle");
  chSpe.add("Blastoise");
  chSpe.add("Charmander");
  chSpe.add("Charmeleon");
  chSpe.add("Charizard");  
 
  centerSubPanel.add(lSpe);
  centerSubPanel.add(chSpe);
  centerSubPanel.add(lEmp);
  centerSubPanel.add(bDone);
  centerSubPanel.add(lNew);
  textArea.setPreferredSize(new Dimension(500, 200));
  textArea.setEditable(false);
  textArea2.setPreferredSize(new Dimension(500, 200));
  textArea2.setEditable(false);
  
  
  textArea.setBackground(Color.white);
  textArea.setEditable(false);
  scroll.setBorder(null);
  centerSubPanel.add(scroll);  //add scrollPane to panel, textArea inside.        
  scroll.getVerticalScrollBar().setPreferredSize(new Dimension(10, 0));
  add("Center", centerSubPanel);
 
  bottomSubPanel.add(lMsg);
 
  bDone.addActionListener(listener); //add listener to button
  bottomSubPanel.add(bClear);
  bClear.addActionListener(listener); //add listener to button 
 //add bottomSubPanel sub-panel to South area of main panel      
  add("South", bottomSubPanel);     

}

This is what my GUI looks like: enter image description here

            add("South", bottomSubPanel);
        }
    }
}

Also, avoid using setPreferredSize, let the layout managers do their job. In the example I'm used insets (from GridBagConstraints) and an EmptyBorder to add some additional space around the components

Also, be careful of using AWT components (ie Choice), they don't always play nicely with Swing. In this case, you should be using JComboBox
