What does ":" mean in this Java statement?

Question

for (Season time : Season.values() )
system.out.println (time+ "\t" + time.getSpan());

I see an example for enumeration using :. What does this mean?

Answer 1

This is the Java syntax for a foreach loop.

The loop will iterate over all the items in the collection of objects returned by Season.values() one at a time, putting each item in turn into the time variable before executing the loop body. See this closely related question for more details on how the foreach loop works.

Answer 2

It is just a token to separate the iterating variable on the left from the array on the right in the new for-each loop
