可以充满整个屏幕的。package basicjava_study.swing;import java.awt.*;
import javax.swing.*;
import com.borland.jbcl.layout.*;public class ImageCoveredButton extends JFrame{    ImageIcon icn;
    JPanel jPanel1;
    JButton jButton1;
    XYLayout xYLayout1;    public ImageCoveredButton(){
        icn = new ImageIcon(getClass().getResource("image/splash.gif"));
        jPanel1 = new JPanel();
        jButton1 = new JButton();
        xYLayout1 = new XYLayout();
        try{
            jbInit();
        }
        catch(Exception e){
            e.printStackTrace();
        }
    }    public static void main(String args[]){
        ImageCoveredButton imageCoveredButton1 = new ImageCoveredButton();
        imageCoveredButton1.pack();
        imageCoveredButton1.show();
    }    private void jbInit()throws Exception{
        setDefaultCloseOperation(3);
        jPanel1.setLayout(xYLayout1);
        jButton1.setForeground(Color.red);
        jButton1.setHorizontalTextPosition(SwingConstants.CENTER);                jButton1.setText("JBuilder");
        jButton1.setIcon(icn);
        getContentPane().add(jPanel1, "Center");
        jPanel1.add(jButton1, new XYConstraints(83, 34, 238, 200));
    }
}
