What is the difference between `Stream.peek()` and `Stream.map()`?

Accepted Answer

Stream.peek() is used for debugging by allowing you to perform an operation on each element without changing it, while Stream.map() transforms elements into potentially different types. This distinction is crucial for understanding how to manipulate data in Java streams effectively.
