Java MCQ: What is the main advantage of using lambda expressions in Java?

Answer:

Explanation:

The main advantage of using lambda expressions in Java is that they reduce the amount of boilerplate code required for anonymous classes. Before the introduction of lambda expressions in Java 8, developers often used anonymous inner classes to implement functional interfaces. This approach, while effective, led to verbose and less readable code.

Lambda expressions allow you to write the same functionality in a more concise and readable way. For example, consider the following code that uses an anonymous inner class:

Runnable runnable = new Runnable() {
    @Override
    public void run() {
        System.out.println("Running");
    }
};

With a lambda expression, the same code can be written as:

Runnable runnable = () -> System.out.println("Running");

This reduction in boilerplate code is one of the key benefits of lambda expressions, making Java code more concise and easier to maintain.
