Method

boolean[][]boolean2array(int sz, boolean seed)
booleanarray 
boolean[][] ret = new boolean[sz][sz];
init(ret, seed);
return ret;
byte[]boolean2bin(boolean b)
booleanbin 
byte[] answer = new byte[1];
answer[0] = ((b) ? TRUE : FALSE);
return answer;
byteboolean2byte(boolean b)
booleanbyte 
if (b) {
    return 1;
} else {
    return 0;
doubleboolean2double(boolean b)
Converts a Boolean value to a Double value. 
return b ? -1D : 0D;
longboolean2long(boolean b)
booleanlong 
return b ? -1L : 0L;
StringbooleanArrayToBitString(final boolean[] booleanArray)
Returns a bit-string representation of the given boolean array. 
final StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < booleanArray.length; i++) {
    if (booleanArray[i]) {
        stringBuilder.append('1');
    } else {
        stringBuilder.append('0');
return stringBuilder.toString();
byte[]booleanArrayToBytes(boolean[] input)
A method that performs the same function as the booleanArrayToByte() method but is not limited by input and output size. 
int count = input.length / 8;
if (input.length % 8 != 0)
    count++;
byte[] out = new byte[count];
int pos = 0;
int bpos = 0;
while (bpos < count) {
    out[bpos] = 0;
...
intbooleanArrayToInt(boolean[] in)
convert an array of booleans - one ber bit to an int 
if (in.length > 32)
    throw new IllegalArgumentException("no more than 32 bits in an int");
int index = 1;
int ret = 0;
for (int i = 0; i < in.length; i++) {
    if (in[i])
        ret |= index;
    index <<= 1;
...
int[]booleanArrayToIntIndexes(boolean[] arrb)
Set elements of arrb true if their indexes appear in arrb. 
int count = 0;
for (int i = 0; i < arrb.length; i++) {
    if (arrb[i]) {
        count++;
int[] intarr = new int[count];
count = 0;
...
StringbooleanArrayToString(boolean[] array)
Creates a string representation of the given array of type boolean[]. 
StringBuffer sb = new StringBuffer();
sb.append("[");
for (boolean a : array) {
    sb.append((a ? 1 : 0) + ", ");
if (sb.lastIndexOf(", ") != -1)
    sb.delete(sb.lastIndexOf(", "), sb.length());
sb.append("]");
