no
if u want a class that can say "im an instance of this interface" then it must have implemented all abstract methods
bronze holly
ohh

u cant say "ICanJump" and then only implement one of the two methods ICanJump demands

Which means you can't use a lambda or method reference, since those only apply to 'functional interfaces' that have a singl abstract method.

yeah
halcyon turret
But you can implement both with an anonymous inner class.
bronze holly
hmm
halcyon turret
It's just not nearly as syntactically convenient.
bronze holly
yeah I'd rather make a class that implements the interface and then make an instance of that class
halcyon turret
Yeap.

also when you said functional interfaces have a single abstract method , does it mean that the interface cannot have defined or concrete methods as well?

its about abstract methods
halcyon turret
No. I meant that you can ignore the non-abstract methods... you can have as many of them as you like (well, up to the bytecode format limit)
