Method

BooleantoBoolean(Object obj)
to Boolean 
if (isNull(obj)) {
    return getNull();
if (obj instanceof Boolean) {
    return (Boolean) obj;
if ("true".equalsIgnoreCase(obj.toString())) {
    return Boolean.TRUE;
...
booleantoBoolean(Object obj)
Converts an object to boolean, according to the following logic:
  1. If it's null, false is returned.
  2. If it's a Boolean, the same object is returned.
  3. If it's any other object, the toString() value is converted to boolean.
if (obj != null) {
    if (obj instanceof Boolean) {
        return (Boolean) obj;
    } else {
        return toBoolean(obj.toString());
} else {
    return false;
...
BooleantoBoolean(Object obj)
Converts an Object to a Boolean. 
if (obj instanceof Boolean) { 
    return (Boolean) obj;
} else if (obj instanceof String) {
    return Boolean.valueOf((String) obj);
} else if (obj == null) {
    return null;
} else {
    return Boolean.FALSE;
...
booleantoBoolean(Object obj)
to Boolean 
try {
    if (obj instanceof String) {
        if (obj.equals("true") || obj.equals("yes")) {
            return true;
        return false;
    } else if (obj instanceof Integer) {
        return ((Integer) obj).intValue() == 1;
...
booleantoBoolean(Object object)
Converts an object to a boolean (return false if the conversion fail) 
if (object instanceof Boolean) {
    return ((Boolean) object).booleanValue();
} else if (object instanceof String) {
    return Boolean.parseBoolean((String) object);
} else {
    return false;
booleantoBoolean(Object object)
to Boolean 
if (object instanceof Boolean) {
    return ((Boolean) object).booleanValue();
if (object instanceof Number) {
    return ((Number) object).intValue() != 0;
return object != null;
BooleantoBoolean(Object object)
to Boolean 
Boolean b = null;
if (object != null) {
    if (object instanceof Boolean)
        b = (Boolean) object;
return b;
booleantoBoolean(Object object)
to Boolean 
if (object.equals(Boolean.TRUE)
        || (object instanceof String && (((String) object).equalsIgnoreCase("true"))
                || ((String) object).equalsIgnoreCase("1"))
        || ((object instanceof Number) && (((Number) object).intValue() == 1))) {
    return true;
return false;
BooleantoBoolean(Object object, Boolean defaultValue)
to Boolean 
if (object == null) {
    return defaultValue;
if (object instanceof Boolean) {
    return ((Boolean) object).booleanValue();
try {
    Boolean value = Boolean.valueOf(object.toString().trim());
...
booleantoBoolean(Object property, boolean defaultValue)
to Boolean 
if (property == null) {
    return defaultValue;
return Boolean.parseBoolean(String.valueOf(property));
