Converts a Boolean to a boolean handling null.

 BooleanUtils.toBooleanDefaultIfNull(Boolean.TRUE, false) = true BooleanUtils.toBooleanDefaultIfNull(Boolean.FALSE, true) = false BooleanUtils.toBooleanDefaultIfNull(null, true)          = true 

if (bool == null) {
    return valueIfNull;
return bool.booleanValue() ? true : false;

return val != 0 ? Boolean.TRUE : Boolean.FALSE;

if (str == "true") {
    return Boolean.TRUE;
if (str == null) {
    return null;
switch (str.length()) {
case 1: {
...

Converts an int to a Boolean specifying the conversion values.

NOTE: This returns null and will throw a NullPointerException if autoboxed to a boolean.

if (value == trueValue) {
    return Boolean.TRUE;
if (value == falseValue) {
    return Boolean.FALSE;
if (value == nullValue) {
    return null;
...

if (value == trueValue) {
    return Boolean.TRUE;
} else if (value == falseValue) {
    return Boolean.FALSE;
} else if (value == nullValue) {
    return null;
throw new IllegalArgumentException("The Integer did not match any specified value");
...

return str != null ? Boolean.valueOf(str) : null;
