Question

I have an array of boolean entries:

boolean[] myBooleanArray = new boolean[24];

Currently i check if it contains true like so:

Arrays.asList(myBooleanArray).contains(true);

Is this the fastest way to check an array of boolean? If not, what is the fastest way to perform this check?

EDIT:

I timed the methods in your answers as follows by running it as an app on an Android 4.03 Samsung S2 device:

boolean[] myBooleanArray = new boolean[24];

long startTime = System.nanoTime();
suggestedMethod(myBooleanArray);
long endTime = System.nanoTime();

long duration = endTime - startTime;
Log.i("timetest", Long.toString(duration));

Time ranking over five runs were, with fastest first:

1. Between 5334 and 11584 ns:

   for (boolean value : myBooleanArray) {
       if (value) {
           return true;
       }
   }
   return false;
   

2. Between 160542 and 171417 ns:

   Arrays.asList(myBooleanArray).contains(true);
   

3. Between 191833 and 205750 ns:

   Booleans.contains(myBooleanArray, true);
   

Answer 1

Just iterate through array

for(boolean value: myBooleanArray){
  if(value){ return true;}
}
return false;
