Java Utililty Methods Boolean Array Convert to

int result = 0;
for (int i = 0; i < b.length; i++) {
 if (b[i]) {
 result += Math.pow(2, i);
return result;

if (array.length == 0)
 return "[]";
StringBuilder sb = new StringBuilder(array.length << 4);
sb.append('[');
for (boolean o : array) {
 sb.append(Boolean.toString(o));
 sb.append(',');
sb.setCharAt(sb.length() - 1, ']');
return sb.toString();
