Description

Wherever we use the enhanced for construction:

    for ( FormalParameter : Expression ) Statement

where the Expression evaluates to an array or collection type that supports random access, we can avoid creating iterator objects, unless we are also using the iterator to remove items while iterating by using the basic for statement instead:

for ( ForInit ; Expression ; ForUpdate ) Statement
