If the "E:\temp" String is a literal String, the compiler treats \t as a tab character; escape the behaviour of the \ by doubling it, e.g. "E:\\temp", or by using the forward slash: "E:/temp".

Try

"E:\\temp"

or use backslash

"E:/temp"

Thank u for quick reply.
The solution you mentioned is goes well when i statically give file path some thing like "E:/temp" .
Actually my requirement is user upload a file i save it in database with file path from where he is selecting the file.In this case case i don't know what exactly the location .The file location for user may contains some characters something like "\t" or "\n" or "\r" etc.. .In that case i can't use as you said.I need a some encoding concept to do this.Some thing like UTF-8 or Unicode encoding .I am not good in encoding . I am very great
full to you if you help me

So there is some part in your software that translates, say, \t to a single tab character, right? If so, double all your \ characters if that software translates the character pair to a single \ character; otherwise find the translation rules of that piece of software because without them the question can't be answered.

Thanks JoasH,
I already did what you said it goes well,but i am not looking for a only "\t" characters.I am looking for more robust code for all special characters ,may be in future i get situation where i need to store special characters(some thing like saving url where we have no of special characters).I am looking in that perspective . I just explained on example where i got problems in strings.Please consider in my point of view and if you have any ideas please suggest me.

You could try to do this:

String encoded= decoded.replacAll("\\", "\\\\");

This code snippet replaces each \ with two \\.
