How to name application and give it an icon?

问题

I'm working in eclipse and I have made an application without name and icon. When i start the application it's a really creepy name displaying in the upper left corner (Mac). It's some thing like. I wonder how I can change this to my own name. Second question is how i can change the icon. Can I do that in eclipse?

If you're using JFrames, you can try setting the icon image as follows.

frame.setIconImage(img); 

Also, by name it sounds a bit like you mean the frame's title. When you create the a frame, you can set the title as follows:

Frame frame = new JFrame("Title goes here");

The prefered method would be to create a Mac OS application bundle (and the bundler), but if this seems like to much work, you can supply custom properties to, for example, you could supply the Xdock:name property when running the application, for example...

-DXdock:name="Application Name"

If you can't do that, you can set it when your application runs, for example...

public static void main(String[] args) {
    try {
        // Sets the application name on the menu bar
        System.setProperty("Xdock:name", "Application Name");

        // Set the applications dock icon...
        Application application = Application.getApplication();            
        application.setDockIconImage(ImageIO.read(TestDockIcon.class.getResource("/Icon.png")));

        // Start the application...
        new TestDockIcon();
    } catch (IOException exp) {
        exp.printStackTrace();
    }
}
