Java: What does the colon (:) operator do?

for (CreditCard cc : credit1)

&

if (index instanceof RewardCard)

is “:” and instanceof the same? so I could use?

if (index : RewardCard)

or

for (CreditCard cc instanceof credit1)

if not, can someone explain what the “:” mean?

Answer 1

They’re not the same: instanceof checks if an instance of an Object is of a certain type. The : in for (CreditCard cc : credit1) is a short way to loop through a List (foreach loop).
