Question

What type define an argument to make sure this is of determinate class and implements determinate interface? I’m using <T extends MyBaseClass & MyInterface> for argument type in method definition but my argument not extends MyBaseClass, IS of MyBaseClass type.
I want to make sure that the argument that I recive are of MyBaseClass type and implements MyInterface

Answer 1

I’m going to assume that you are asking if you can do something like this —

public <T extends YourBaseClass, YourInterface> void foo(T bar) {

The answer is yes, you can. If you try passing an argument into this method thats YourBaseClass, but does not implement YourInterface, then the code will not compile.
