You can’t directly convert it to string. You should implement something like this Add this code to your method //Commented this out because this is not the efficient way to achieve that //StringBuilder builder = new StringBuilder(); //int ch; //while((ch = fis.read()) != -1){ // builder.append((char)ch); //} // //System.out.println(builder.toString()); Use Aubin’s solution: public static String … Read more
If you are consistently doing small reads then a BufferedInputStream will give you significantly better performance. Each read request on an unbuffered stream typically results in a system call to the operating system to read the requested number of bytes. The overhead of doing a system call is may be thousands of machine instructions per … Read more

In FileInputStream, the method read() reads a single byte. From the source code: /** * Reads a byte of data from this input stream. This method blocks * if no input is yet available. * * @return the next byte of data, or <code>-1</code> if the end of the * file is reached. * @exception … Read more
An InputStream is the raw method of getting information from a resource. It grabs the data byte by byte without performing any kind of translation. If you are reading image data, or any binary file, this is the stream to use. A Reader is designed for character streams. If the information you are reading is … Read more
InputStream is; try { is = new FileInputStream(“c://filename”); is.close(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return is;
You can use the length() method on File which returns the size in bytes.
The java.io.File and consorts acts on the local disk file system. The root cause of your problem is that relative paths in java.io are dependent on the current working directory. I.e. the directory from which the JVM (in your case: the webserver’s one) is started. This may for example be C:\Tomcat\bin or something entirely different, … Read more
