Is there a way to create an instance of a particular class given the class name (dynamic) and pass parameters to its constructor.

Something like:

Obj         


        

Answer 1

You can also invoke methods inside the created object.

You can create object instant by invoking the first constractor and then invoke the first method in the created object.

    Class c = Class.forName("mypackage.MyClass");
    Constructor ctor = c.getConstructors()[0];
    Object object=ctor.newInstance(new Object[]{"ContstractorArgs"});
    c.getDeclaredMethods()[0].invoke(object,Object... MethodArgs);
