Java Programming for Complete Beginners - Java 16 - Step 08 - Do While Loop in Java - an Example - Cube While User Enter

The video tutorial explains how to create a simple Java program that repeatedly asks the user for a number and prints its cube until a negative number is entered. It covers the use of the 'do while' loop, handling user input with the Scanner class, and optimizing code by minimizing object creation. The tutorial also addresses edge cases and ensures the program runs efficiently, providing a practical example of using loops in Java.

What is the significance of the initial value assigned to the number variable?

In what way does the program handle edge cases when the user enters invalid input?

How does the program ensure that the user is prompted at least once for input?
