What are some advanced techniques in Java and Python?

In Java, you can explore features like Streams, Lambda expressions, and the Java Concurrency framework. In Python, advanced techniques include decorators, generators, and context managers. Would you like to dive deeper into any specific area?

Can you explain how to use decorators in Python?

Sure! Decorators in Python are a way to modify or enhance functions or methods. They are defined using the '@decorator_name' syntax before the function definition. For example, you can create a simple logging decorator that prints the function name before executing it.

What about using Streams in Java?

Java Streams allow you to process sequences of elements, such as collections, in a functional style. You can perform operations like filtering, mapping, and reducing in a concise way. Would you like to see an example?

Yes, please provide an example of using Streams.

Here's a simple example: you can use Streams to filter a list of integers to get only even numbers. List<Integer> evenNumbers = numbers.stream().filter(n -> n % 2 == 0).collect(Collectors.toList()); This will give you a list of even integers.
