public interface CharIterable
extends Iterable<Character>
A type-specific Iterable that strengthens that specification of iterator() and forEach(Consumer).

Note that whenever there exist a primitive consumer in java.util.function (e.g., IntConsumer), trying to access any version of forEach(Consumer) using a lambda expression with untyped arguments will generate an ambiguous method error. This can be easily solved by specifying the type of the argument, as in 

    intIterable.forEach((int x) -> { // Do something with x });

The same problem plagues, for example, PrimitiveIterator.OfInt.forEachRemaining(java.util.function.IntConsumer).

Warning: Java will let you write “colon” for statements with primitive-type loop variables; however, what is (unfortunately) really happening is that at each iteration an unboxing (and, in the case of fastutil type-specific data structures, a boxing) will be performed. Watch out.
