- Q4. What is use of Method reference instead lambada expressions in java 8?
- Ans.
Method references provide a more concise way to refer to methods by name instead of using lambda expressions.
Method references can make code more readable and maintainable by reducing boilerplate code.
They can be used to refer to static methods, instance methods, and constructors.
Example: list.forEach(System.out::println) is equivalent to list.forEach(item -> System.out.println(item)).
