Fundamentals Of Object-Oriented Programming: Java and IntelliJ - Program: Custom Message Based on Weekday

The video tutorial explains how to create a Java program that prompts users to enter a day of the week and outputs a custom message for each day. It covers creating an enum class for the days, a day checker class with a constructor, and using a switch statement to print messages. The tutorial also demonstrates handling user input with a scanner and converting it to match the enum type.

What is the primary purpose of the program introduced in the video?

• To convert days into numbers

• To create a calendar application

• To prompt the user to enter a day and display a message

• To calculate the number of days in a week

What is the role of the enum class in the program?

• To handle errors

• To store user input

• To perform calculations

• To define the days of the week

What is the purpose of the day checker class?

• To store the days of the week

• To check the entered day and display a message

• To handle user input errors

• To convert days into numbers

How does the program determine which message to display for each day?

• Using a while loop

• Using a for loop

• Using a switch statement

• Using a series of if-else statements

What happens if the user enters a day that is not recognized by the program?

• The program ignores the input

• The program asks for input again

• The program crashes

• A default message is displayed

What method is used to convert user input to match the enum definitions?

• toLowerCase

• toUpperCase

• trim

• substring

What is the purpose of the scanner object in the main method?

• To perform calculations

• To display messages

• To handle user input

• To store days of the week
