What are for-each expressions in Java translated to? [duplicate]

Question

 for ( SomeListElement element : objectWithList.getList() ) { ... } 

What is the above snippet translated to?

What I am mostly interested in is if the getList() method called once, or with each iteration/element?

Answer 1

Its equivalent to

for(Iterator<SomeListElement> i = objectWithList.getList().iterator();                                                                i.hasNext(); ) {   SomeListElement element = i.next();   //access element here } 

Answer 2

It gets translated to below code snippet, and objectWithList.getList() is called only once.

for (Iterator i = objectWithList.getList().iterator(); i.hasNext();) {     SomeListElement e = (SomeListElement) i.next(); }
