    Default Problem with byte and short data type

    Hello,

    When I use byte and short for number method, I have an error. (when I change byte to int and short to int, the problem was fixed)

    Thanks

    and error is:

    Exception in thread "main" java.lang.Error: Unresolved compilation problem:
    The method number(byte, long, double, short, short) in the type MainClass is not applicable for the arguments (int, long, double, int, int)

    at MainClass.main(MainClass.java:9)

    The method number(byte, long, double, short, short) in the type MainClass is not
    applicable for the arguments (int, long, double, int, int)
    The method number is defined to take parameters of the type shown in the error message. The code that calls the number method needs to use those data types that match.

    The code might compile if the wrong types were cast to int. Cast by adding (int) in front of the variable name.
    If you don't understand my answer, don't ignore it, ask a question.

    Thank you,

    But why should we cast to int? I want to use byte and short.

    Method call is:
    number(19,52608968L,2828282d,373,28337);

    Sorry, the cast I suggested could be backwards. Did you try to cast the args that are being passed to be the same as the ones the method requires?

    Did you try casing the arguments in the call to number to the required types?
