Creating an unreferenced array in Java?

Say I have a method such as:

public void printElements(int[] array)

How could I send an int[] as an argument without declaring it previously (so, actually create it inside the message). I want to avoid something like:

int[] anArray = { 5, 3, 10 };
Foo.printElements(anArray);

And use something (although this doesn't work) like this instead:

Foo.printElements( new int{ 5, 3, 10 } );

new int[]{ 5, 3, 10 } – Mike Jun 09 '14 at 21:37
Depending on how you want to use this function, it may be worth considering a `...` argument. `public void printElements(int... nums)` can be called with `Foo.printElements(anArray)` or `Foo.printElements(1, 2, 3)`. – user2357112 supports Monica Jun 09 '14 at 21:39
You should also take a look at vararg methods, since they seem to be exactly what you want. – yshavit Jun 09 '14 at 21:39
@user2357112 it is not if you want to sent other parameters as well after the array. – Luiggi Mendoza Jun 09 '14 at 21:39
I tried researching and I found nothing about it. Anyway thanks guys, I feel pretty silly now :D – KingDragonRider Jun 09 '14 at 21:40
