Add Icon to Menu Item
提问by ARDA
I want to add ImageIconto JMenuItemto illustrate actions like Newor save.
Why isn't the following code working for me?
我想添加ImageIcontoJMenuItem来说明诸如New或save 之类的操作。
为什么以下代码对我不起作用？
JMenu file = new JMenu("File");
menubar.add(file);
JMenuItem newgame = new JMenuItem("New");
file.add(newgame);
newgame.setIcon(new ImageIcon("/Project1/zkre/new.gif"));

By the looks of your code you have your Imagepackaged in your jar file, you should use getResourceAsStream(..)or getResource(..)to extract it from the jar like so (Exception Handling omitted):
根据您的代码的外观，您已将其Image打包在 jar 文件中，您应该 像这样使用getResourceAsStream(..)或getResource(..)从 jar 中提取它（省略了异常处理）：
ImageIcon imageIcon=new ImageIcon(ImageIO.read(getClass().getResourceAsStream("/Project1/rawaz/new.gif")));
NBmake sure the case of your file name and its path are correct (as Windows file system is not case sensitive but files inside the jar are handled by JVM which is case sensitive).
注意确保您的文件名及其路径的大小写正确（因为 Windows 文件系统不区分大小写，但 jar 中的文件由区分大小写的 JVM 处理）。

Maybe make sure if you are getting the right image path:
也许确定您是否获得了正确的图像路径：
java.net.URL imageURL = this.getClass().getResource("YOUR_IMAGE_PATH");
System.out.println(imageURL); //imageURL is printing correctly in console
ImageIcon image = new ImageIcon(imageURL);
// now add the image to your menubar

Instead of what you wrote, do that and make sure of your path image.
而不是你写的，这样做并确保你的路径图像。
newgame.setIcon(new ImageIcon(getClass().getResource("/Project1/zkre/new.gif")));

You can just move your images file to your main project folder.
您可以将图像文件移动到主项目文件夹。
E.g:
例如：
\workspace\YOUR_PROJECT_NAME\IMAGES_FILE
\workspace\YOUR_PROJECT_NAME\IMAGES_FILE
