How to input in the fileinputstream, a file to url?

I enter the url in the Fileinputstream, but the output of the URL is wrong, because the link slashes are turned backwards like - from / to \ and the double slashes // are \ only one slash and backwards.Is there a way with the fileinputstream to do that ? If it isn't, can you tell me what should I use instead of fileinputstream?

回答1:

If you want to obtain an InputStream to retrieve data from a URL, then using the URL.openStream method will return an InputStream, which can be used like any other InputStream.

For example,

InputStream is;

// if we were getting data from a file, we might use:
is = new FileInputStream("/path/to/file");

// or, from a URL, then retrieve an InputStream from a URL
is = new URL("http://google.com/").openStream();
