Question

I have to write a code in JAVA like following structure:

Read String From File
// Perform some string processing
Write output string in file

Now, for reading/writing string to/from file, I am using,

BufferedReader br = new BufferedReader(new FileReader("Text.txt"), 32768);
BufferedWriter out = new BufferedWriter(new FileWriter("AnotherText.txt"), 32768);

  while((line = br.readLine()) != null) {
          //perform some string processing
          out.write(output string) ;
          out.newLine();
    }

However, it seems reading and writing is quite slow. Is there any other fastest method to read/write strings to/from a file in JAVA ?

Additional Info:

1) Read File is 144 MB.
2) I can allocate large memory (50 MB) for reading or writing.
3)I have to write it as a string, not as Byte.

Answer 1

It sounds slower than it should be.

You can try increasing the buffer size.

Maybe also try FileOutputStream instead of FileWriter.

You mentioned 50MB. Are you modifying the memory parameters of the program at all when you run it using a -X switch?
