Instantiate dynamic object in java [duplicate]

This question already has an answer here:

• Creating an instance using the class name and calling constructor 7 answers

I would like to ask you guys if how can I instantiate an object from a string?

Ex:

Methods meth = new MethodsImpl();

Note: Methods = Interface MethodsImpl = Class

Is there anyway I can do that from a string? Something like this.

String thisMethod = "Method"
String thisMethodImpl = "MethodImpl"

thisMethod meth = new thisMethodImpl();

Something like that? I know its not possible but is there any way how I can do that? Im going to instantiate a dynamic object by the way.

thanks!
