Scala & Spark-Master Big Data with Scala and Spark - Default Arguments

The video tutorial explains the concept of default parameters in Scala, demonstrating how they allow functions to have default values for parameters, preventing exceptions when no arguments are passed. It covers the importance of parameter order and provides examples of using multiple default parameters. The tutorial concludes with a complex example to solidify understanding.

Explain what happens when a function is called without passing any parameters.

What are default parameters in Scala and how do they function?

How does Scala handle default values when a parameter is not provided?

Describe a scenario where an exception might be raised due to parameter mismatch.

What is the significance of the order of parameters when using default arguments?

What will happen if you pass multiple parameters to a function with default values?

How can you ensure that default arguments are correctly assigned in a function call?
