Method

TvalueOf(Class cls, String s)
value Of 
try {
    return Enum.valueOf(cls, s);
} catch (IllegalArgumentException e) {
s = s.toLowerCase();
T theOne = null;
for (T value : cls.getEnumConstants()) {
    if (value.toString().toLowerCase().startsWith(s)) {
...
TvalueOf(Class en, String name)
Gets the value of an enum from a name. 
if (name == null)
    return null;
try {
    return Enum.valueOf(en, name);
} catch (IllegalArgumentException e) {
    return null;
TvalueOf(Class enumType, String constantName)
This works like Enum#valueOf(Class,String) but returns null if constant wasn't found instead of throwing an IllegalArgumentException. 
try {
    T constant = Enum.valueOf(enumType, constantName);
    return constant;
} catch (IllegalArgumentException ex) {
    return null;
TvalueOf(Class enumType, String name)
value Of 
return valueOf(enumType, name, null);
TvalueOf(Class enumType, String name)
value Of 
return valueOf(enumType, name, null);
TvalueOf(Class enumType, String name)
Null-safe valueOf function 
if (name == null) {
    return null;
return Enum.valueOf(enumType, name);
TvalueOf(Class enumType, String name, T defaultValue)
value Of 
try {
    return Enum.<T>valueOf(enumType, name);
} catch (Exception e) {
    return defaultValue;
EnumvalueOf(final Class enumType, final String value)
Convert a string to an enum. 
return Enum.valueOf((Class<Enum>) enumType, value);
ObjectvalueOf(final Class type, final String value)
Convert a string value to a boxed primitive type. 
if (type == String.class) {
    return value;
if (type == boolean.class) {
    return Boolean.valueOf(value);
if (type == int.class) {
    return Integer.valueOf(value);
...
EvalueOf(final Class clazz, final String name)
value Of 
if (clazz == null) {
    return null;
final E[] es = clazz.getEnumConstants();
for (final E e : es) {
    if (e.name().equalsIgnoreCase(name)) {
        return e;
return null;
