Java Utililty Methods Boolean Array And

boolean[] and(boolean a[], boolean b[])
Computes vector whose elements are the results of logical AND 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[] and(boolean[] x, boolean[] y)
and

if (x == null || y == null || x.length != y.length)
 return null;
boolean[] result = new boolean[x.length];
for (int i = 0; i < x.length; i++) {
 result[i] = x[i] & y[i];
return result;

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

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;

boolean[] andRows(boolean[][] data)
Take the logical AND of all variables in each row

boolean[] result = new boolean[data.length];
for (int i = 0; i < data.length; i++) {
 result[i] = true;
 for (int j = 0; j < data[i].length; j++) {
 result[i] &= data[i][j];
return result;

void ANDWith(boolean[] toChange, boolean[] toAdd)
AND With

if (toChange.length != toAdd.length)
 throw new IllegalArgumentException("Array sizes have to be equal.");
for (int i = 0; i < toAdd.length; i++) {
 toChange[i] = toAdd[i] && toChange[i];
