-

i passing josn object java php. using jdk 1.8 ang wamp server. below java code. 

import java.io.ioexception; import org.apache.http.client.methods.httppost; import org.apache.http.entity.stringentity; import org.apache.http.impl.client.closeablehttpclient; import org.apache.http.impl.client.httpclientbuilder; import org.json.simple.jsonobject;  /**  *  * @author preeet dash  */ public class fromjava  {     public static void main(string[] args) throws ioexception     {         jsonobject json = new jsonobject();         json.put("somekey", "somevalue");              closeablehttpclient httpclient = httpclientbuilder.create().build();          try          {             httppost request = new httppost("http://localhost/pgp/jsonreq/tophp.php");             stringentity params = new stringentity(json.tostring());             request.addheader("content-type", "application/json");             request.setentity(params);             httpclient.execute(request);         // handle response here...         } catch (exception ex)          {             system.out.println("error: cannot estabilish connection");                 }                   {             httpclient.close();         }     }     }

php script:

$data = json_decode(file_get_contents("php://input")); echo($data);

when run php file shows empty page. can please me understand why not working.

when run following php code executes else condition.

if ($_server['request_method'] == 'post')     {         $data = json_decode(file_get_contents("php://input"));         echo($data);     }     else     {         echo "xxxxxx";     }

i not think work.

a php script not "listening" webservice. however, upon receiving request, script processes , try "print" result in html, not java.

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.
