Getting a file from classpath

In file handling we most of the times need to locate a file from classpath. Though locating a file is not a rocket science but still I have seen people getting stuck doing this and ultimately hardcoding the file path at the required place.

Following is a code snippet which locates a file from classpath and returns its absolute path.

ClassLoader loader = Thread.currentThread().getContextClassLoader();
URL url = loader.getResource(“name_of_file.extension”);
String file = url.getFile().replace(“%20″, ” “);//this is required as URL treats space //as %20.

Some of the IO APIs of Java takes URI also as input, so URL can be converted to URI using url.toURI() method.

Small but important things must be kept handy

Hi,

I am back on my favorite space after a long break. It has been a year or more I guess since I have not written any posts on this blog. I had been busy in learning lots and lots of stuff and now I feel I have few things which may prove helpful for technocrats like us. There are times when you get stuck in something which are small but tricky. You even find the solution but due to time crunch or some other reason you forget to keep a note of that. And when after a long time you face the same problem or someone else faces the problem then you realize that it would have been better if you had saved that particular solution. This often happens to me and I have to waste my time and effort to reinvent the wheel. So I have decided to put those kind of solutions on this blog so that it can be reused at any point of time.

Suggestions and contributions to this blog are welcome.
