objectinputstream - java initializing variable for stream in/out -

-

i have problem below code. not clear how can initialize variables of in/out.

during creation of object program hangs when in constructor. hangs @ line of this.inobjects = new objectin.......... create in/out objects once read , write on input/output, strings , objects calling them in methods , applying read write etc etc

where going wrong? possible not receiving data hangs? shouldn't, right?

public class pokerclient  {     private pokerclientgui gui;     private socket clientsocket;     private datainputstream in;     private dataoutputstream output;     private objectinputstream inobjects;     private objectoutputstream outobjects;     private hand hand;      //constructor     public pokerclient()     {         try         {             this.gui= gui;             this.clientsocket = new socket("localhost", 4444);             this.in = new datainputstream(this.clientsocket.getinputstream());             this.inobjects = new objectinputstream(this.clientsocket.getinputstream());             this.output = new dataoutputstream(this.clientsocket.getoutputstream());             this.outobjects = new objectoutputstream(this.clientsocket.getoutputstream());         }         catch (exception e)         {         } }

you should create object output stream first , flush it. should never wrap same stream 2 different ways. never catch exception , ignore unless having errors , no way determine has gone wrong. don't assign field itself, won't useful, confuse people.

public class pokerclient {   private final pokerclientgui gui;   private final socket clientsocket;   private final objectoutputstream outobjects;   private final objectinputstream inobjects;    public pokerclient(pokerclientgui gui) throws ioexception {     this.gui = gui;     clientsocket = new socket("localhost", 4444);     outobjects = new objectoutputstream(clientsocket.getoutputstream());     outobjects.flush();     inobjects = new objectinputstream(clientsocket.getinputstream());   } }

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
