2. How can we create this calculator layout?
Modify the code below to put the operators above the buttons…

/// in the constructor…
setLayout(new BorderLayout());
JPanel panel = createButtonPanel();
add(panel,BorderLayout.CENTER);
public JPanel createOperationPanel() {
JPanel panel = new JPanel();
panel.add(new JButton("+"));
panel.add(new JButton("-"));
panel.add(new JButton("*"));
panel.add(new JButton("/"));
return panel; }

3. Get to know your classmates
Turn to a neighbor, and find out who traveled farther over Christmas break
When you have determined who traveled farther, that person should raise his hand
