    Pseudo code suggestion:
    Java Code:
    String target = "friend";
    String line = a_line_read_from_file
    if(line.indexOf(target) != -1) {
        //this line has the target string in it
        int index = line.indexOf(target) + target.length();
        if(index != -1)
            char nextChar = line.charAt(index);

    Perhaps you want to use the method suggested above, charAt(...)?
