我正在使用NetBeans 6.1作为我的主IDE,在那里我无法运行由Sun提供的这个启动画面示例(它会抛出一个nullpointerExeption)。但我可以使用这些参数在命令行上运行它。
java -splash:filename.gif SplashDemo
我不知道如何在NetBeans中注入命令行参数。请有人帮忙。
import java.awt.*;
import java.awt.event.*;
public class SplashDemo extends Frame implements ActionListener {
static void renderSplashFrame(Graphics2D g, int frame) {
final String[] comps = {"foo", "bar", "baz"};
g.setComposite(AlphaComposite.Clear);
g.fillRect(120, 140, 200, 40);
g.setPaintMode();
g.setColor(Color.BLACK);
g.drawString("Loading " + comps[(frame / 5) % 3] + "...", 120, 150);
}
public SplashDemo() {
super("SplashScreen demo");
setSize(300, 200);
setLayout(new BorderLayout());
Menu m1 = new Menu("File");
MenuItem mi1 = new MenuItem("Exit");
m1.add(mi1);
mi1.addActionListener(this);
this.addWindowListener(closeWindow);
MenuBar mb = new MenuBar();
setMenuBar(mb);
mb.add(m1);
final SplashScreen splash = SplashScreen.getSplashScreen();
if (splash == null) {
System.out.println("SplashScreen.getSplashScreen() returned null");
return;
}
Graphics2D g = splash.createGraphics();
if (g == null) {
System.out.println("g is null");
return;
}
for (int i = 0; i < 100; i++) {
renderSplashFrame(g, i);
splash.update();
try {
Thread.sleep(90);
} catch (InterruptedException e) {
}
}
splash.close();
setVisible(true);
toFront();
}
public void actionPerformed(ActionEvent ae) {
System.exit(0);
}
private static WindowListener closeWindow = new WindowAdapter() {
public void windowClosing(WindowEvent e) {
e.getWindow().dispose();
}
};
public static void main(String args[]) {
SplashDemo test = new SplashDemo();
}
}

转到项目属性(右键单击项目,然后选择属性)。 从“类别”列表中选择“运行”项。 在那里你可以设置参数,VM选项等。
