这里面包含了一百多个JAVA源文件

When the size of the button component is larger than its contents, the label and icon are always kept together. In fact, the gap size (see e749 Setting the Gap Size Between the Label and Icon in a JButton Component) determines the fixed distance between them. Using two alignment methods, you can place the label/icon pair in one of nine possible locations. 
    // To create a button with an icon, see e746 Adding an Icon to a JButton Component
    
    // Place the contents in the nw corner
    button.setVerticalAlignment(SwingConstants.TOP);
    button.setHorizontalAlignment(SwingConstants.LEFT);
    
    // Place the contents centered at the top
    button.setVerticalAlignment(SwingConstants.TOP);
    button.setHorizontalAlignment(SwingConstants.CENTER);
    
    // Place the contents in the ne corner
    button.setVerticalAlignment(SwingConstants.BOTTOM);
    button.setHorizontalAlignment(SwingConstants.RIGHT);
    
    // Place the contents in the sw corner
    button.setVerticalAlignment(SwingConstants.BOTTOM);
    button.setHorizontalAlignment(SwingConstants.LEFT);
    
    // Place the contents centered at the bottom
    button.setVerticalAlignment(SwingConstants.BOTTOM);
    button.setHorizontalAlignment(SwingConstants.CENTER);
    
    // Place the contents in the se corner
    button.setVerticalAlignment(SwingConstants.BOTTOM);
    button.setHorizontalAlignment(SwingConstants.RIGHT);
    
    // Place the contents vertically centered on the left
    button.setVerticalAlignment(SwingConstants.CENTER);
    button.setHorizontalAlignment(SwingConstants.LEFT);
    
    // Place the contents directly in the center
    button.setVerticalAlignment(SwingConstants.CENTER);
    button.setHorizontalAlignment(SwingConstants.CENTER);
    
    // Place the contents vertically centered on the right
    button.setVerticalAlignment(SwingConstants.CENTER);
    button.setHorizontalAlignment(SwingConstants.RIGHT);
