Fundamentals Of Object-Oriented Programming: Java and IntelliJ - Program: User Input - Voting Age

This video tutorial explains how to accept user input in Java using the Scanner library. It covers creating a Scanner object, prompting the user for their name and age, and storing these inputs. The tutorial also demonstrates how to use conditional statements to check if the user is eligible to vote based on their age. Finally, it shows how to run the program and interpret the output.
