Question

hi in C++ we can have enum of follwoing type:

enum e_acomany {    Audi=4,     BMW=5,      Cadillac=11,    Ford=44,    Jaguar=45,      Lexus,      Maybach=55,     RollsRoyce=65,      Saab=111  };

can we have the similar enum in java. This question might seems childish but i am new to java enum please give me the answer and also provide some links to example.

Answer 1

You can define enum values with associated numbers:

public enum Company {

    AUDI(4), BMW(5), CADILLAC(11), FORD(44), JAGUAR(45), ...;

    private final int id;

    private Company(int id) {
        this.id = id;
    }
}

You can then write your own method to convert an id to a Company value. But fundamentally enums are pretty different in Java to C++, and you may well not want to use them in exactly the same situations.
