arrays - JAVA REFLECTION : java.lang.IllegalArgumentException: argument type mismatch -

-

am using java reflection, here using object org.openqa.selenium.remote.remotewebelement, call method called sendkeys. method accept charactersequence array parameter type, passing charactersequence[] parameter . using classname.getmethod(sendkeys, charactersequence[]) can methodname. when method innvoked in runtime passing array of charactersequences[] argument throws 

java.lang.illegalargumentexception: argument type mismatch @ sun.reflect.nativemethodaccessorimpl.invoke0(native method) @ sun.reflect.nativemethodaccessorimpl.invoke(nativemethodaccessorimpl.java:62) @ sun.reflect.delegatingmethodaccessorimpl.invoke(delegatingmethodaccessorimpl.java:43) @ java.lang.reflect.method.invoke(method.java:497) @ com.thbs.manager.reflections.callseleniumcommand(reflections.java:115) @ com.google.manager.testing.dotestexecution(testing.java:105) @ com.google.manager.testing.main(testing.java:22)

could not post entire code,but posted code throws error 

objtocallwith = org.openqa.selenium.remote.remotewebelement cls = objtocallwith.getclass();  methodname = sendkeys params = charsequence[].class // send keys method accept charsequence[] mymethod = cls.getmethod(methodname, params);  // able getmethod  args = new charsequence[]{'a','b'} // here exception java.lang.illegalargumentexception: argument type mismatch mymethod.invoke(objtocallwith,args);

mymethod.invoke(objtocallwith,args);

should changed to:

mymethod.invoke(objtocallwith, new object[]{args});

or

mymethod.invoke(objtocallwith, (object)args);

this because method.invoke accepting varargs arguments. so, mymethod.invoke(objtocallwith,args); equivalent mymethod.invoke(objtocallwith,"a", "b");, gives two charsqeunce objects, rather one charsqeuqnce[] array object.

as might know, foo(charsequence... args) internally compiled foo(charsqeuqnce[] arg). so, when call foo("a", "b"), internally foo(new charsequence[]{"a", "b"}), one charsequence[] array object.

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.
