I'm coming from a C++ background, so be kind on my n00bish queries...

I'd like to read data from an input file and store it in a stringstream. I can accomplish this in an easy way in C++ using stringstreams. I'm a bit lost trying to do the same in Java.

Following is a crude code/way I've developed where I'm storing the data read line-by-line in a string array. I need to use a string stream to capture my data into (rather than use a string array).. Any help?

    char dataCharArray[] = new char[2];
    int marker=0;
    String inputLine;
    String temp_to_write_data[] = new String[100];

    // Now, read from output_x into stringstream

    FileInputStream fstream = new FileInputStream("output_" + dataCharArray[0]);

    // Convert our input stream to a BufferedReader
    BufferedReader in = new BufferedReader (new InputStreamReader(fstream));

    // Continue to read lines while there are still some left to read
    while ((inputLine = in.readLine()) != null )
    {
        // Print file line to screen
        // System.out.println (inputLine);
        temp_to_write_data[marker] = inputLine;
        marker++;
    }
