suppose i have classA and classB(generic), reference <http://www.exampledepot.com/egs/java.lang.reflect/Constructors.html>

I am passing a customobject from classA to classB, now i am wanting constructor of customobject in classB and call it 

classA

```
customclass objCustomclass;

classB mClassB;

mClassB.getConstructorAndCall(objCustomclass);

```

classB

```
public void getConstructorAndCall(Object objCustomclass);

try {
    Object filledObject = objCustomclass.getClass().newInstance();
        // here i need to call  filledObject's contructor
} catch (Exception e) { }

```

I am able to create object as the instance of custom object but what about constructor.

note: `getConstructorAndCall()` is a commom method and in that object is of unknown type that means any class can pass its object.

Thanks.
