    <p>Okay guys, back with another question. Why do I get identifier expected in line 64 at around the timer. I put in the Timer identifier and it complains at me. Someone please tell me what's wrong with this code:</p> <pre><code>import java.awt.*; import java.awt.event.*; import javax.swing.*; public class RpsNuke extends JFrame implements ActionListener { private final char moves[] = {'R', 'P', 'S', 'N'}; private JRadioButton rock, paper, scissors, nuke; private JTextField display; public RpsNuke() { super("Rock, Paper, Scissors, Nuke"); rock = new JRadioButton(" Rock ", true); paper = new JRadioButton(" Paper "); scissors = new JRadioButton(" Scissors "); nuke = new JRadioButton(" Nuke "); ButtonGroup rpsButtons = new ButtonGroup(); rpsButtons.add(rock); rpsButtons.add(paper); rpsButtons.add(scissors); rpsButtons.add(nuke); JButton go = new JButton(" Go "); go.addActionListener(this); display = new JTextField(25); display.setEditable(false); display.setBackground(Color.yellow); Container c = getContentPane(); c.setLayout(new FlowLayout()); c.add(rock); c.add(paper); c.add(scissors); c.add(go); c.add(nuke); c.add(display); if (nuke.isSelected()){ display.setText("Don't do it man");} else { display.setText("");} } /** * returns -1 if the player wins, * 0 if it's a tie, and 1 if the computer wins */ private int nextPlay(char computerMove, char playerMove) { if ((computerMove == 'R'&amp;&amp;playerMove == 'S')||(computerMove == 'S'&amp;&amp;playerMove=='P')||(computerMove=='P'&amp;&amp;playerMove=='R')){ return 1;} else if ((computerMove == 'R'&amp;&amp;playerMove == 'R')||(computerMove=='S'&amp;&amp;playerMove=='S')||(computerMove=='P'&amp;&amp;playerMove=='P')){ return 0;} else if (playerMove == 'N'){ return 2;} return -1; } timer = new Timer(1000, new ActionListener() { public void actionPerformed(ActionEvent evt) { timer:stop(); char playerMove, computerMove; playerMove = 0; if (rock.isSelected()){ playerMove = 'R';} else if (paper.isSelected()){ playerMove = 'P';} else if (scissors.isSelected()){ playerMove = 'S';} else if (nuke.isSelected()){ playerMove = 'N';} int k = (int)(Math.random() * 3); computerMove = moves[k]; int result = nextPlay(computerMove, playerMove); String msg = ""; if (result != 2) {msg = " You said " + makeWord(playerMove) + ", I said " + makeWord(computerMove); if (result &lt; 0){ msg += " -- you win.";} else if (result == 0){ msg += " -- tie.";} else if (result &gt; 0){ msg += " -- I win.";} } else if (result == 2) { timer:start(); msg = "It's too late, we're all dead!"; msg = "..."; msg = "Look at what you did, there's nothing left."; msg = "Looks like we have to start over again..."; timer.stop(); main(null); } display.setText(msg); } }); private String makeWord(char move) { String word = ""; switch (move) { case 'R': word = "rock"; break; case 'P': word = "paper"; break; case 'S': word = "scissors"; break; case 'N': word = "nuke"; break; } return word; } public static void main(String[] args) { Rps window = new Rps(); window.setBounds(300, 300, 300, 140); window.setDefaultCloseOperation(EXIT_ON_CLOSE); window.setVisible(true); } } </code></pre>

    1. COeven though i cant see the line numbers your method is ending before timer. I think you have an extra closing bracket.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
