Index out of bound exception with inputstream data

Question

I was trying to flush data in a file in my local machine to response. But at some point I get an IndexOutOfBoundsException.

FileInputStream inputStream = new FileInputStream(downloadFile);
OutputStream outStream = response.getOutputStream();
byte[] buffer = new byte[4096];
int bytesRead = -1;
while ((bytesRead = inputStream.read(buffer, 0, 4096)) != -1) {
    outStream.write(buffer, 0, bytesRead);
}
inputStream.close();
outStream.close();

The above code is what I was trying. The downloadFile path given is correct and it works till the while loop. But then the IndexOutOfBoundsException occurs. I tried it with inputStream.read(buffer) but that didn't work.

Answer 1

Give code is working perfectlly; since there is no information is given regarding the response object I have modify the OutputStream to FileOutputStream; just to test.

Below code segment is working perfectly.

public class Test
{
    public static void main(String args[]) throws IOException
    {
        FileInputStream inputStream = new FileInputStream("C:\\readme.txt");
        FileOutputStream outputStream = new FileOutputStream("D:\\readme1.txt");
        //OutputStream outStream = response.getOutputStream();
        byte[] buffer = new byte[4096];
        int bytesRead = -1;
        while ((bytesRead = inputStream.read(buffer, 0, 4096)) != -1) {
            outputStream.write(buffer, 0, bytesRead);
        }
        inputStream.close();
        outputStream.close();
    }
}
