Java: Iteration and Traversal
Answer
A simplified iteration construct for collections and arrays.
The enhanced for loop, introduced in Java 5, allows straightforward iteration over arrays and collections like Lists and Sets. It improves readability by abstracting the iterator usage. For example, iterating over a list of product names can be done using: `for (String product : productList) { System.out.println(product); }`, which avoids the boilerplate of initializing an iterator.
