如何修改此Client类以从字符串数组中读取输入（而不是从标准输入中读取）？

Question

I have the following code, in a Java Client class ( it's this KnockKnock client/server pair ) :

   try {
      kkSocket = new Socket("localhost", 4444);
      out = new PrintWriter(kkSocket.getOutputStream(), true);
      in =  KKJokes[0]; //new BufferedReader(new InputStreamReader(kkSocket.getInputStream()));
      // in2 = new BufferedReader(new InputStreamReader(kkSocket.getInputStream()));
    }

I want to have it automatically read from a String array (that contains all those predefined Jokes ) , something like this :

       String KKJokes[] =  {"Who's there?", "Turnip who?", 
           "y", "Who's there?", "Who's there?", "blah" };
        /* more cod */
       try {
          kkSocket = new Socket("localhost", 4444);
          out = new PrintWriter(kkSocket.getOutputStream(), true);

       for (int i = 0; i< KKJokes.length; i++) {
          in =  new BufferedReader( new InputStreamReader( KKJokes[i] )) ; 
       }
      }

But this doesn't work, it gives :

KnockKnockClientRedux.java:33: non-static variable KKJokes cannot be referenced from a static context
      for (int i = 0; i< KKJokes.length; i++) {
                         ^ KnockKnockClientRedux.java:34: non-static variable KKJokes cannot be referenced from a static context
      in =  new BufferedReader( new InputStreamReader( KKJokes[i] )) ; //new Buf feredReader(new InputStreamReader(kkSocket.getInputStream()));
                                                       ^ KnockKnockClientRedux.java:34: cannot find symbol symbol  : constructor InputStreamReader(java.lang.String) location: class java.io.InputStreamReader
      in =  new BufferedReader( new InputStreamReader( KKJokes[i] )) ; //new Buf feredReader(new InputStreamReader(kkSocket.getInputStream()));

EDIT: Wouldn't it be easier to just read from a text file? Maybe I'll list all the KnockNock joke lines vertically in a text file. That way, it seems easier to swap in a FileReader for the kkSocket.getInputStream() code

Answer 1

The compiler message tells it all. Try with

static String KKJokes[] =  {"Who's there?", "Turnip who?", 
       "y", "Who's there?", "Who's there?", "blah" };

The second problem can be solved with:

new InputStreamReader( new ByteArrayInputStream(KKJokes[i].getBytes() )
