What is the difference between `Stream.generate()` and `Stream.iterate()` for creating infinite streams?

Accepted Answer

`Stream.generate()` and `Stream.iterate()` differ in how they create infinite streams. `generate()` uses a Supplier to produce independent values, while `iterate()` uses a seed and UnaryOperator to create a stateful sequence.
