Enhanced for Loop

The enhanced for loop has the following characteristics:

• Simplified iteration over collections

• Much shorter, clearer, and safer

• Effective for arrays

• Simpler when using nested loops

• Iterator disadvantages removed

Iterators are error prone:

• Iterator variables occur three times per loop.

• This provides the opportunity for code to go wrong.
