In Java, an interface is an abstract type used to declare a behavior that classes must implement. Interfaces can only contain method signatures and constant declarations, and starting from Java 8, they can also have default and static methods with implementation. Interfaces cannot be instantiated but are implemented by classes, allowing for multiple inheritance-like behavior.
