I am receiving return value in the form of long or int from Native code in Android, which I want to convert or match with enum, for processing purpose. Is it possible ? How?

Cast Int To Enum may be of some help. Go with the 2nd option. The 1st one can cause an exception if the integer is out of the defined range in your Enumeration. In current example I compare to 'magic number' but in real application I am getting data from integer field from DB.
You can explicitly type cast an int to a particular enum type, as shown below.
equals method uses == operator internally to check if two enum are equal. This means, You can compare Enum using both == and equals method.
If you have full control of values and enums, and they're sequential, you can use the enum ordinal value:
enum Heyo { FirstVal, SecondVal } ...later int systemVal = [whatever]; Heyo enumVal = Heyo.values()[systemVal]; int againSystemVal = enumVal.ordinal(); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
