    Anyone know do all primitives indirectly implement serializable in java, which makes them legal types for parameter passing in rmi.

    Don't they get boxed into their non-primitive equivalents?

    My understanding is that primitives implement nothing because they're, well, primitives i.e. not a class (that can implement an interface) or an interface (that can extend an interface).

    All of the primitives respective wrapper classes do implement serializable, and comparable:

    Primitive - Wrapper Class
    boolean - Boolean
    byte - Byte
    char - Character
    double - Double
    float - Float
    int - Integer
    long - Long
    short - Short

    hth,
    causal
