通过Tcp发送数据后，字符串比较不起作用

Question

I have following code. One reads a File called "denglish.txt" splits it into words and sends every 2nd word over Tcp socket connection to a server. The Server is now supposed to read this word and compare a to a word from a dictionary. Weird thing is the comparison always fails if i send it that way. But if the clients sends something like out.Print("make") it works . I really dont understand why its like this. I can send and print out the word from the client on the Server and he prints out the correct words but the stringcompare fails. MAybe someone can help me. THank you guys

    Socket socket = new Socket ("localhost" , 47777);
        PrintWriter out = new PrintWriter(socket.getOutputStream(),true);
        //Socket socket1 = new Socket ("localhost" , 47778);
        //PrintWriter out1 = new PrintWriter(socket1.getOutputStream(),true);


            String line;
            BufferedReader text = new BufferedReader(new InputStreamReader(new FileInputStream("denglisch.txt")));
            String text1 = "";


           while((line = text.readLine()) != null) {  // handle lines
                text1 = text1 + line;
                }

           int i = 0;
           //out.println("make");
           StringTokenizer tokenizer = new StringTokenizer( text1,",.\" : !" );
           while ( tokenizer.hasMoreTokens() )
           {
                if (i % 2 == 0)
                    {

                    out.println(tokenizer.nextToken().toLowerCase().toString());
                    out.flush();
                    }
                if (i % 2 ==1 )
                    {
                    //out1.println(tokenizer.nextToken());
                    }
                i = i+1;

Answer 1

text1 = text1 + line; You don't use a space or a delimiter in here. Can that be the problem? )(What I mean is that you print several words, like CatHouseDogFood which isn't a word in the dictionary). It would make sense why it works when you only print one word (ie "make")

What do you get if you print the compareTo result at server side?
