Description

The list of methods to do Boolean And are organized into topic(s).

Method

booleanand(boolean a, boolean b)
and 
return a && b;
booleanand(boolean b1, boolean b2)
Concatenate two booleans with the operation "AND"
return b1 && b2;
booleanand(boolean val1, boolean val2)
Returns (val1 && val2). 
return val1 && val2;
booleanand(boolean... bools)
An and gate 
boolean total = true;
for (boolean bool : bools)
    total = total && bool;
return total;
booleanand(boolean... bs)
and 
boolean r = true;
for (boolean b : bs) {
    r = b && r;
return r;
Booleanand(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;
BooleanandBoolOperand(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;
