An interface declaration may be preceded by interface modifiers:

InterfaceModifiers:

	InterfaceModifier

	InterfaceModifiers InterfaceModifier

InterfaceModifier: one of

	public abstract

The access modifier public is discussed in §6.6. A compile-time error occurs if the same modifier appears more than once in an interface declaration.

9.1.2.1 abstract Interfaces

Every interface is implicitly abstract. This modifier is obsolete and should not be used in new Java programs.
