Java Utililty Methods xor

boolean xor(boolean a, boolean b)
Perform an either/or operator

return (a && !b) || (b && !a);

boolean[] xor(boolean a[], boolean b[])
Computes vector whose elements are the results of logical XOR of the respective elements in the two given vectors.

boolean[] c = new boolean[a.length];
for (int i = 0; i < c.length; i++) {
 c[i] = a[i] ^ b[i];
return c;

boolean xor(boolean b1, boolean b2)
Concatenate two booleans with the operation "XOR"

return (b1 != b2);

boolean xor(boolean b1, boolean b2)
xor

if (b1 == false && b2 == false) {
 return false;
} else if (b1 == false && b2 == true) {
 return true;
} else if (b1 == true && b2 == false) {
 return true;
} else {
 return false;
...

boolean xor(boolean o, boolean t)
xor

return !xnor(o, t);

boolean xor(boolean val1, boolean val2)
Returns (val1 != val2).

return (val1 != val2);

boolean xOr(boolean x, boolean y)
x Or

return ((x || y) && !(x && y));

boolean xor(boolean... bools)
An xor gate

boolean didOr = false;
boolean total = false;
for (boolean bool : bools) {
 if (total && bool) {
 if (didOr)
 return false;
 } else {
 total = total || bool;
...

boolean xor(boolean[] array)

Performs an xor on a set of booleans.

 BooleanUtils.xor(new boolean[] { true, true }) = false BooleanUtils.xor(new boolean[] { false, false }) = false BooleanUtils.xor(new boolean[] { true, false }) = true 

if (array == null) {
 throw new IllegalArgumentException("The Array must not be null");
} else if (array.length == 0) {
 throw new IllegalArgumentException("Array is empty");
int trueCount = 0;
for (int i = 0; i < array.length; i++) {
 if (array[i]) {
...

boolean[][] xor(boolean[][] b1, boolean[][] b2)
xor

boolean[][] temp = new boolean[b1.length][b1[0].length];
for (int i = 0; i < b1.length; i++) {
 for (int j = 0; j < b1[0].length; j++) {
 temp[i][j] = b1[i][j] ^ b2[i][j];
return temp;
