Java Programming for Complete Beginners - Java 16 - Step 02 - Functional Programming - First Example with Function as Pa

The video tutorial introduces functional programming by setting up a project and creating a class. It explains the concept of functional programming, emphasizing functions as first-class citizens. The tutorial contrasts procedural and functional programming using a list example, demonstrating how to print list elements using both approaches. It introduces lambda expressions, showing how they enable passing functions as parameters, a key aspect of functional programming.

What is the first step in setting up a new project for functional programming?

• Run the project

• Create a new project

• Add a main method

• Create a new package

Which programming paradigm is used in the initial list example?

• Logical programming

• Declarative programming

• Procedural programming

• Functional programming

What is the purpose of using 'list.stream()' in functional programming?

• To sort the list

• To convert a list into a stream of values

• To filter the list

• To convert a list into a set

What is a lambda expression used for in functional programming?

• To define a class

• To create a new project

• To pass a function as a parameter

• To declare a variable

In functional programming, what is the significance of passing functions as parameters?

• It simplifies the syntax

• It improves the speed of execution

• It enables functions to be treated as first-class citizens

• It allows for more efficient memory usage

What does the 'forEach' method do in a stream?

• It sorts the elements

• It applies a specified action to each element

• It filters the elements

• It removes duplicates

What is the main concept introduced in the final section of the video?

• Data encapsulation

• Functions as first-class citizens

• Procedural programming

• Object-oriented programming
