Body
copied!<p>When I put in my JPanel to work with a BorderLayout, it tells me: <code>constructer JPanel in class JPanel cannot be applied to given types; required: no arguments; found: BorderLayout; reason: actual and formal argument lists differ in length;</code></p> <p>Here is my code:</p> <pre><code>public class MTGSAMPServerReference extends JFrame implements ActionListener { public static Toolkit tk = Toolkit.getDefaultToolkit(); static int ScrnWidth = ((int) tk.getScreenSize().getWidth()); static int ScrnHeight = ((int) tk.getScreenSize().getHeight()); private static final long serialVersionUID = 1L; private static JList list1; private static JButton next; public MTGSAMPServerReference() { // set flow layout for the frame this.getContentPane().setLayout(new FlowLayout(FlowLayout.LEADING)); Object[] data1 = { "Value 1", "Value 2", "Value 3", "Value 4", "Value 5" }; JPanel controls = new JPanel( new BorderLayout(5,5) ); // The line getting the main error. list1 = new JList<Object>(data1); list1.setVisibleRowCount(5); next = new JButton("Next"); next.addActionListener(this); controls.add(new JScrollPane(list1)); // A result error of the JPanel error ^ controls.add(next, BorderLayout.PAGE_END); // A result error of the JPanel error ^ // adjust numbers as needed. controls.setBorder(new EmptyBorder(25,25,0,0)); add(controls); // A result error of the JPanel error ^ // add list to frame add(list1); add(next); } @Override public void actionPerformed(ActionEvent e) { if (e.getActionCommand().equals("Next")) { int index = list1.getSelectedIndex(); System.out.println("Index Selected: " + index); String s = (String) list1.getSelectedValue(); System.out.println("Value Selected: " + s); } } private static void createAndShowGUI() { //Create and set up the window. JFrame f = new MTGSAMPServerReference(); //Display the window. f.pack(); f.setVisible(true); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setSize(1200, 800); f.setLocationRelativeTo(null); list1.setSize(250, 250); list1.setLocation(0, 0); next.setSize(75, 25); next.setLocation(251, 276); } public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } } </code></pre> <p>What is missing in my code? I have all of my imports, and I am sure it is just a minor error, perhaps a typo.</p> <p>Any and all help is appreciated!</p> <p>Thanks in advance!</p> <p>EDIT: Here are the imports I have:</p> <pre><code>import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.border.*; </code></pre>
