Sorry the code which I posted earlier was not properly indented.

Second version compiles without error for me.
Indentation is still useless - here's Eclipse's version.

class HelloWorldApp {

   public static void main(String[] args) {
      try {
         // Open the file that is the first 
         // command line parameter
         String fname = args[0];
         int x = 0;
         FileInputStream fstream = new FileInputStream(fname);
         // Get the object of DataInputStream
         DataInputStream in = new DataInputStream(fstream);
         BufferedReader br = new BufferedReader(new InputStreamReader(in));
         String strLine = "", str1 = "";
         //Read File Line By Line
         while (x < 2) {
            // Print the content on the console
            strLine = br.readLine();
            x++;
            if (x == 1) str1 = strLine;
            if (x == 2) {
               str1 = str1 + " " + strLine;
            }
            // System.out.println (str1);

Stop posting your CSCI561 code to the internet. You are going to cause others to copy your code.

Stop posting your CSCI561 code to the internet. You are going to cause others to copy your code.

I don't know whether this is addressed to techie929 or to me, but either way your criticism is unfounded.

techie929 posted his code because he wanted help with compile errors. That's what we do here, we help people, and if he didn't post his code we couldn't help.

I took the code from his second post, ran it through Eclipse's source formatter and re-posted it so he could see that his idea of "properly indented" wasn't that good. I personally have no idea what CSCI561 is.

maybe LabsID

maybe so, perhaps I should have said "personally I neither know nor care care what CSCI561 is"!
I just had my feathers ruffled by a first-time anonymous poster criticising a perfectly normal and valid series of Daniweb posts. Time to move on...

that's true,

negative
... other hand, this forum has "more of democracy" as another forum where I meberber of, that very ... and counterproductive, topic by topic is very same, someone spllit out, hmmm then there is so difficult to choose if this post is about lazzynes, total ignore, soooo stopt and this people really need our hepl, maybe she/he want to learn more, yes, no or maybe its hard to decide, the result is superficiality

good/possitive ...but here isn't arrogance and personal attack
