Method

booleanbooleanValue(Boolean b, boolean def)
boolean Value 
return (b != null) ? b.booleanValue() : def;
booleanbooleanValue(Boolean value)
Return the boolean value. 
if (value == null)
    return false;
else
    return value.booleanValue();
booleanbooleanValue(final Boolean booleanValue)
Get the boolean value of the Boolean. 
return booleanValue == null ? false : booleanValue.booleanValue();
booleanbooleanValue(Object arg)
boolean Value 
if (arg instanceof Boolean)
    return ((Boolean) arg).booleanValue();
else
    return Boolean.parseBoolean(arg.toString());
booleanbooleanValue(Object associationValue)
boolean Value 
boolean associationEvaluation = true;
if (associationValue != null) {
    if (associationValue instanceof Number) {
        if (((Number) associationValue).intValue() == 0) {
            associationEvaluation = false;
    } else if (associationValue instanceof String) {
        String associationValueString = (String) associationValue;
...
booleanbooleanValue(Object obj, boolean defaultValue)
boolean Value 
if (obj != null) {
    if (obj instanceof Boolean) {
        return ((Boolean) obj).booleanValue();
