How colon : used in for{} loop?
for { : }
I was supposed to fill in some objects, but I have no idea how a : character is used in a for loop?
Any comments?

Taking a Java test I found a for{} loop which had a : character in it?... like this...
for { : }
I was supposed to fill in some objects, but I have no idea how a : character is used in a for loop?

The enhanced for loop (in reality, an application of the Iterator) allows you to do something with each object in a collection. The syntax then is to tell the compiler that, for each object in the collection, do something ...
for( String s [THE OBJECT WHICH IS THE CURRENT ELEMENT] : myArrayList [THE COLLECTION])
{
replace( s, a);
}
