how to use reflection to determine whether an Interface has a default method?
Question
I'm like to figure out which methods in an Interface has a default method.
For example, in java.util.Collection, stream() has a default method. How would one go about programmatically finding that out

You can get all the methods from an interface from its Class<?>.getMethods() : myInterface.getMethods() .
Each of those Method objects has a function isDefault() : thisMethod.isDefault() .
