Valid Call in Java

[chiasien]

Hi All,

I am new learner for Java.

My doubt is:

public static void mystery (int list [], int size)

parameter: int list [], int size

declaration: int [] alpha = new int[50]


Q: Produce a valid call to the method mtstery.
My answer: mystery(alpha,50); (isn't correct?)

BTW what is the valid call mean?

Thanks and appreciate for the assist.

Well, syntactically speaking even mystery(null, -42) is quite a valid method call.
Also mystery(new int[42], 54) would be fine. There is no way to enforce that the
second parameter reflects the length of the frst parameter. The caller can do
whatever it wants. The mystery() method should check the validity of its parameters
itself in order to make it a 'valid' call.

Personally I'd had made it a mystery(int[] anArray) method; that int size thing
seems redundant.

kind regards,

Looks like a trick question to me, unless you have omitted some code from your example. Otherwise it is not valid Java, since every function must belong to a class.
