What are alternatives to lambda expressions and how do they compare?

Alternatives to lambda expressions in Java include anonymous inner classes, method references, functional interfaces, and traditional implementations. Each of these approaches has its own advantages and disadvantages, depending on the use case and required readability.

// Example of using an anonymous inner class List names = Arrays.asList("Alice", "Bob", "Charlie"); // Using anonymous inner class Collections.sort(names, new Comparator() { @Override public int compare(String s1, String s2) { return s1.compareTo(s2); } }); // Using Lambda expression Collections.sort(names, (s1, s2) -> s1.compareTo(s2)); // Using Method reference Collections.sort(names, String::compareTo);
