Java Classic Examples是我买的两本书：《JAVA经典实例》和《java入门经典源代码》里边附送光盘里带的源码

public class TryFlowLayout
{
  // The window object
  static JFrame aWindow = new JFrame("This is a Flow Layout"); 

  public static void main(String[] args)
  {
    Toolkit theKit = aWindow.getToolkit();         // Get the window toolkit
    Dimension wndSize = theKit.getScreenSize();    // Get screen size

    // Set the position to screen center & size to half screen size
    aWindow.setBounds(wndSize.width/4, wndSize.height/4,   // Position
                      wndSize.width/2, wndSize.height/2);  // Size
    aWindow.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);

    FlowLayout flow = new FlowLayout(FlowLayout.LEFT);  // Create a layout manager
    Container content = aWindow.getContentPane();  // Get the content pane
    content.setLayout(flow);                       // Set the container layout mgr

    // Now add six button components
    for(int i = 1; i <= 6; i++)
      content.add(new JButton("Press " + i));      // Add a Button to content pane

    aWindow.setVisible(true);                      // Display the window
  }
