Scala & Spark-Master Big Data with Scala and Spark - Solution 2 (While Loop)

The video tutorial covers the use of while loops with logical operators, demonstrating how to combine them effectively to meet specific criteria. It then transitions into implementing a grading system using if-else statements, detailing the logic for assigning grades based on marks. A dry run of the grading logic is performed to illustrate how conditions are evaluated. Finally, the video addresses handling invalid input, ensuring the system prompts for valid marks within a specified range.

What happens when the marks entered are less than 50?

How does the program handle invalid input for marks?
