What are the advantages of using lambda expressions in programming?

Lambda expressions in Java allow creating anonymous functions that can be used for concise writing of functional interfaces. Main advantages:

• Conciseness and readability: reduce boilerplate code, especially when working with collections and streams.
• Functional programming style: simplify passing behavior as parameters, increasing flexibility and modularity.
• Improved API Stream handling: easily describe filtering, transformation, and data aggregation operations.

Example of using a lambda expression to sort a list of strings by length:

List<String> names = Arrays.asList("Anna", "John", "Elizabeth");
names.sort((a, b) -> Integer.compare(a.length(), b.length()));
System.out.println(names); // [Anna, John, Elizabeth]
