Java Utililty Methods Boolean And

boolean and(boolean a, boolean b)
and

return a && b;

boolean and(boolean b1, boolean b2)
Concatenate two booleans with the operation "AND"

return b1 && b2;

boolean and(boolean val1, boolean val2)
Returns (val1 && val2).

return val1 && val2;

boolean and(boolean... bools)
An and gate

boolean total = true;
for (boolean bool : bools)
 total = total && bool;
return total;

boolean and(boolean... bs)
and

boolean r = true;
for (boolean b : bs) {
 r = b && r;
return r;

Boolean and(Boolean... operands)
n-ary and that ignores null values.

Boolean result = null;
for (Boolean operand : operands) {
 if (operand == null) {
 continue;
 if (!operand) {
 return false;
 result = true;
return result;

Boolean andBoolOperand(Boolean o, Boolean a)
And 2 Boolean operands in the context of pruning match Operand one|Operand another | And result unknown | T | unknown unknown | F | F unknown | unknown | unknown T | T | T T | F | F T | unknown | unknown F | T | F F | F | F F | unknown | F

if (o == null) {
 if ((a == null) || a) {
 return null;
 } else {
 return a;
} else if (a == null) {
 return o ? null : Boolean.FALSE;
