Thread: Multiple generic types

Hi. I am learning JAVA programming language. I created a generic class:
Here is the code for it

Code:

Public interface myclass <T,U>
{
  ...
}

With that, I can instantiate objects like this:

Code:

mylcass <String, boolean> a = new myclass <String,boolean>();

What I do here please guide me:

Code:

myclass <String> a= new myclass <String>();

Is there a way to make an optional type with generics? Any help would be highly appreciated.

I think there is an error in the code and you can change it in this way,

Code:

myclass <String, Object> a = new myclass <String,Object>();

Hope this will resolve your problem.

Try to understand following code which is helpful for you .Check out this

Code:

myclass <String,Boolean> a = new myclass <String,Boolean>();

in place of use the following in your code

Code:

myclass <String, boolean> a = new myclass <String,boolean>();

I hope you know the differences between the two.
