提问by Ibrahim AKGUN
i am new at java so maybe this will be a silly question. I got a file in my jasper.deneme package. I wanna give a full path for it.As ya see in picture i write it like
我是 Java 新手，所以也许这将是一个愚蠢的问题。我的 jasper.deneme 包中有一个文件。我想给它一个完整的路径。正如你在图片中看到的那样，我把它写成
string fullpath = "/jasper.deneme/reportDeneme.jasper";
but it does not workin :)
但它不起作用:)
so how can i get this file's path?
那么我怎样才能得到这个文件的路径呢？
回答by Michael Borgwardt
denemeJasper.class.getResource("reportDeneme.jasper").getPath()
denemeJasper.class.getResource("reportDeneme.jasper").getPath()
If you need the path for reading the file's contents, it would be simpler (and safer) to use getResourceAsStream()and avoid having to deal with paths entirely.
如果您需要读取文件内容的路径，则使用起来会更简单（也更安全），getResourceAsStream()并且不必完全处理路径。
BTW, your class denemeJasperviolates ubiquitous Java naming standards; as a class, its name should start with an uppercase letter.
顺便说一句，您的类denemeJasper违反了无处不在的 Java 命名标准；作为一个类，它的名字应该以大写字母开头。

The might be better off with a relative path, but the absolute path would be:
使用相对路径可能会更好，但绝对路径将是：
String fullpath = "/jasper/deneme/reportDeneme.jasper";
'/'replaces '.'in the package name whether the resource is located in a file, a jar or by any other means.
'/''.'无论资源位于文件、jar 还是任何其他方式，都在包名称中替换。
