Problem in reading this particular text file, what is the problem with it..

[Hindusthan Kamal]

Hai to all..,

I had developed an application to read the text file that is stored in my computer from mobile, all are working fine but some files create problems in reading the file content, like the file i had attached with this..

Can any one please tell why this particular file creates problem in reading the contents...

I had attached a text file with this...

and the code I am using is

int getcharcount;
FileInputStream fstream = new FileInputStream(filename);
InputStreamReader in = new InputStreamReader(fstream);
while ((getcharcount = in.read()) != 0)
{
	getchar = getchar + (char) getcharcount;
}
System.out.println("Full File Content :"+getchar);

I try'd with BufferedReader also, but have the same problem,

Can any one please give me a solution for this..

I imagine "getchar" is a String that's initialized to "" -- you haven't shown its declaration.

read() doesn't return "0" except when you read the character whose value is 0; read() returns -1 to indicate end of file, so your loop should test for -1. If your file doesn't contain a 0 -- and text files generally won't! -- then this will loop forever. Change that 0 to a -1 and this will work.

That said, this is horrifying code -- it's about the least efficient way to read a file into a String that I could imagine. Something like this is infinitely better:

    StringBuilder builder = new StringBuilder();
    FileReader reader = new FileReader(file);
    char[] buffer = new char[1024];
    int n;
    try {
        while ((n = reader.read(buffer)) != -1) {
            builder.append(buffer, 0, n);
        }
    } finally {
        reader.close();
    }   
    String result = builder.toString();

Thanks for you reply Ernest Friedman-Hill

It's an wounder full suggestion...

I try'd with your code it's working fine but with this code also it's generates some error in reading some files.(I had attached a text file please try your code with this file).

Content in this file is not important but the first two lines are important, if we can read the first two lines its enough to get the name from the contact number and the date sent.

Try it and please guide me through this...

Have a great day...!!!
