How colon : used in for{} loop?

[Joncamp]

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?

Any comments?

Hi!

Are u sure it is of the format u provided above? or shown as below:

public class ForeachArray {
public static void main(String args[]) {
String[] data = { "Asia", "Japan" };
for (String s : data) {
System.out.println(s);
}
}
}

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);
}
