Java socket communication -

-

i have problem program. explain use example:

i have 2 programs, , b. controls b sockets, have client , b server.

the client code:

package clienttimer;  import java.io.*; import java.net.*;  import javax.swing.joptionpane;   import java.net.*; import java.io.*;  public class client {         private string action;         private string ip;          public client(string action,string ip) {                 this.action=action;                 this.ip=ip;                 string servername = "server";                 int port = 9999;                 try {                         socket client = new socket(ip, port);                         outputstream outtoserver = client.getoutputstream();                         dataoutputstream out = new dataoutputstream(outtoserver);                         out.writeutf(action);                         inputstream infromserver = client.getinputstream();                         datainputstream in =new datainputstream(infromserver);                         new countdown(in.readutf(),true);                         client.close();                 }catch(ioexception e) {                         e.printstacktrace();                 }         } }

the b server code: 

package servertimer;  import java.io.bufferedreader; import java.io.bufferedwriter; import java.io.ioexception; import java.io.inputstreamreader; import java.io.outputstreamwriter; import java.io.printwriter; import java.net.serversocket; import java.net.socket; import java.net.socketexception;  import java.net.*; import java.io.*;  public class server extends thread {    private string correct;     public server() {        run();    }      public void run() {            correct="q";          try {             serversocket serversocket = new serversocket(9999);             while(true) {               socket server = serversocket.accept();               datainputstream in = new datainputstream(server.getinputstream());               new viewer(in.readutf());               dataoutputstream out = new dataoutputstream(server.getoutputstream());               if (correct.length()==5) {                   out.writeutf(correct);               } else {                   out.writeutf("a");               }               server.close();            }          }catch(sockettimeoutexception s) {             system.out.println("socket timed out!");          }catch(ioexception e) {             e.printstacktrace();          }    } }

as can see, client send , receive string, same server. problem is: server must send tostring() method (in code string called "correct") of object in same package client. don't know how can it. object tostring method initialized in file of package (the viewer(string)).

thanks.

edit: i'm sorry, little bit difficult me explain it. in simple scheme need is: says "do something" -> b says "i that" -> or outputstream-> b inputstream - b outputstream -> inputstream. have problems b outputstream -> inputstream. outputstream must send string product tostring() method of class (in b package).

the program timer controlled remotely, package have controller , b package have viewer. send commands b via socket, need b "occasionally" send a "report" current time.

i can't write program here, it's "big". if want can send email file.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
