A: While both are functional interfaces, a Function produces a result, whereas a Predicate returns a boolean.

Q3: Can you chain multiple functions together in Java 8?
A: Yes, you can use methods like andThen() to chain multiple functions, creating a pipeline of transformations.

Q4: Provide an example of using Function for data transformation.

Q5: How does the apply() method in a Function contribute to its purpose?
A: The apply() method takes an argument and produces a result based on the defined function, allowing for versatile data transformations.
