java - 保留默认值并避免异常是否合法？

Question

    private int getScreenWidth(){
        int width;
        try{
            Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
            width = screenSize.width >= 1024 ? screenSize.width : 1024;
        }catch(HeadlessException e){
            logger.write("couldnt get screen width" + e);
            width = 1024;
        }
        return width;
    }

Answer 1

嗯，不。 HeadlessException得到

thrown when code that is dependent on a keyboard, display, or mouse is called in an environment that does not support a keyboard, display, or mouse.

在没有有屏幕的环境中强制屏幕尺寸是没有意义的。

在这种情况下，应用程序应该退出而不是恢复到默认值。
