What are some examples of using map in Java Streams?

Can you explain how the map function works in Java Streams?

Sure! The map function in Java Streams is used to transform each element of a stream into another form. It takes a function as an argument and applies it to each element.

Can you give me some examples of using map with a list of integers?

Absolutely! For instance, if you have a list of integers and you want to square each number, you can use map like this: list.stream().map(x -> x * x).collect(Collectors.toList());.

What if I want to convert a list of strings to their lengths?

You can do that too! You would use: list.stream().map(String::length).collect(Collectors.toList()); This will give you a list of the lengths of each string.

Are there any other useful operations I can perform with streams?

Yes, you can use operations like filter, reduce, and forEach to manipulate and process your data in various ways.
