Java Programming for Complete Beginners - Java 16 - Step 06 - Functional Programming versus Structural Programming - a Q

The video tutorial discusses the process of summing odd numbers using programming techniques. It contrasts functional programming with procedural programming, highlighting the differences in handling variable mutations and focusing on what to do rather than how to do it. The tutorial also covers code refactoring for improved readability and explains the concept of mutations in code. The aim is to provide a clear understanding of functional programming principles and their advantages over traditional procedural methods.

What function is used to filter odd numbers from a list in the functional approach?

• map

• sort

• reduce

• filter

In the functional programming approach, what is the main advantage of using 'reduce'?

• It filters the numbers.

• It sorts the numbers.

• It multiplies the numbers.

• It sums the numbers.

What is a key difference between functional and procedural programming as discussed in the video?

• Functional programming focuses on 'what to do' rather than 'how to do it'.

• Procedural programming avoids variable mutations.

• Functional programming uses more memory.

• Procedural programming is faster.

How does functional programming handle variable mutations?

• It uses loops to handle mutations.

• It uses global variables to manage mutations.

• It avoids mutations by not changing variable values.

• It encourages frequent mutations.

What is emphasized in functional programming to simplify code logic?

• Using complex loops

• Focusing on 'how to do it'

• Using multiple local variables

• Avoiding variable mutations
