Question

I am new to Java Swing.I want to design one JToolBar. The JToolBar should be placed in center of JPanel. Is it possible?

javax.swing.JPanel pane = new javax.swing.JPanel(); 
BorderLayout border = new BorderLayout(); 
pane.setLayout(border); 
JToolBar toolBar = new JToolBar(); 
pane.add(toolBar,BorderLayout.CENTER); 
javax.swing.JButton button1 = new javax.swing.JButton("Click Me"); 
toolBar.add(button1);

Read about How to use ToolBars.

The following code is taken straight from the doc.

public ToolBarDemo() {
    super(new BorderLayout());
    ...
    JToolBar toolBar = new JToolBar("Still draggable");
    addButtons(toolBar);
    ...
    setPreferredSize(new Dimension(450, 130));
    add(toolBar, BorderLayout.PAGE_START);
    add(scrollPane, BorderLayout.CENTER);
}

See the usage of BorderLayout here. And do the necessary changes in your code.

UPDATE:

I have tried using your code which shows output like this. I have used addSeparator method with dimension. This is just a try to solve the problem. I am not sure whether this approach is the correct way.

public static void main(String[] args) {
    JFrame frame = new JFrame();
    JPanel panel = new JPanel(new BorderLayout()); 
    JToolBar toolBar = new JToolBar(); 
    panel.add(toolBar,BorderLayout.PAGE_START);

    toolBar.addSeparator(new Dimension(150, 0));

    JButton button1 = new JButton("Click Me"); 
    toolBar.add(button1);
    frame.setLayout(new BorderLayout());
    frame.add(panel, BorderLayout.CENTER);
    frame.setSize(new Dimension(400, 100));
    frame.setVisible(true);
}
