What are some advanced usages of lists in Java?

In Java, advanced usages of lists include using streams for processing, custom comparators for sorting, and implementing the List interface with custom classes.

Can you explain how to use streams with lists?

Sure! You can use streams to filter, map, and collect data from lists. For example, you can filter a list of integers to get only even numbers using list.stream().filter(n -> n % 2 == 0).collect(Collectors.toList());.

What about using custom comparators?

Custom comparators allow you to define your own sorting logic. You can implement the Comparator interface and override the compare method to sort lists based on specific criteria.

Can you give an example of a custom comparator?

Certainly! Here's an example: Collections.sort(myList, (a, b) -> a.getName().compareTo(b.getName())); This sorts a list of objects based on their names.
