Fastest way to check if an array of boolean contains true

Question

I have an array of boolean entries:

boolean[] myBooleanArray = new boolean[24];

Currently i check if it contains

Answer 1

If you are using the Guava library (which has a lot of useful stuff):

Booleans.contains(myBooleanArray, true);

(JavaDoc)

The documentation of this method also describes another way. You can replace a boolean[] with a BitSet (should be more memory efficient) and call !bitSet.isEmpty() to check whether at least one bit is true.
