You can't write something in to a resource, assume that you packed your resource as a jar. Jar is only read only. You can't update that. Either you can extract the jarand edit the contents.
您不能在资源中写入内容，假设您将资源打包为 jar。罐子是唯一的read only。你不能更新那个。您可以提取jar并编辑内容。
You can try Preferencesas an alternative
您可以尝试使用首选项作为替代
