Can an interface method have a body in Java?

Question

Java

I recently had an interview.
When asked what an interface is, I answered that "it is a collection of abstract classes that do not have a body."
To this they said that a method in the interface can have a body from some version of Java, but they don’t remember which one.
Is it so?

Answer 2

Body can (and must) have static, default (Java 8), and private (Java 9) methods.
