Fundamentals Of Object-Oriented Programming: Java and IntelliJ - Flow Control: Switch Statement Program - Print Weekday

The video tutorial explains the use of switch statements in programming for decision-making. It covers how to evaluate expressions, define cases for days of the week, and use the default keyword for unmatched cases. The tutorial also demonstrates using a while loop to allow continuous execution of the program, prompting users for input and handling out-of-range values.

What is the primary purpose of a switch statement in programming?

• To iterate over a collection of elements

• To declare variables

• To handle exceptions

• To execute a block of code based on a specific condition

What happens when a case in a switch statement is matched?

• The switch statement is ignored

• The program terminates

• The corresponding block of code is executed

• The program continues to the next case

Why is the break statement used in a switch case?

• To handle errors

• To exit the switch statement after a case is executed

• To continue to the next iteration

• To declare a new variable

What is the role of the default keyword in a switch statement?

• To terminate the program

• To declare a default variable

• To repeat the switch statement

• To execute code when no case matches

How does the program respond when a user inputs a number outside the range of 1 to 7?

• It terminates the program

• It prints 'selected day was out of range'

• It defaults to a specific case

• It prints the corresponding day of the week

What is the advantage of using a switch statement over multiple if-else conditions?

• It allows for more complex logic

• It uses less memory

• It is faster in execution

• It simplifies the code and improves readability

What is the purpose of wrapping a switch statement in a while loop?

• To improve performance

• To handle exceptions

• To allow the program to run indefinitely until manually stopped

• To execute the switch statement only once
