Java Programming for Complete Beginners - Java 16 - Step 09 - Java Switch Statement - Exercises - isWeekDay, nameOfMonth

This video tutorial covers exercises related to switch statements in programming. It includes creating methods to determine if a day is a weekday, the name of a month, and the name of a day using switch statements. The tutorial also discusses optimizing switch statements by using fall-through to simplify code. Viewers are encouraged to try exercises independently before reviewing solutions.

What is the purpose of the 'default' keyword in a switch statement?

• To terminate the switch statement

• To specify a case that matches all conditions

• To handle cases not explicitly covered by other case labels

• To initialize variables within the switch

In the exercise to determine if a day is a weekday, what does the number 0 represent?

• Sunday

• Saturday

• Friday

• Monday

Which method is used to format code automatically in Eclipse?

• Shift + Enter

• Control + Shift + F

• Alt + F4

• Control + C

What is the return type when determining the name of the day?

• String

• Character

• Integer

• Boolean

What happens if a switch case does not have a break statement?

• The next case is executed (fall-through)

• The switch statement terminates

• The default case is executed

• The program crashes

What is the benefit of using a return statement in a switch case?

• It makes the code harder to read

• It increases the execution time

• It allows multiple cases to execute

• It eliminates the need for a break statement

How can you simplify a switch statement with multiple cases returning the same value?

• By adding more break statements

• By using a loop

• By combining cases with fall-through

• By using nested if statements

Which days are considered weekends in the 'isWeekday' exercise?

• Monday and Friday

• Saturday and Sunday

• Tuesday and Saturday

• Wednesday and Thursday

What is the output when the day number is 5 in the 'isWeekday' exercise?

• Error

• Null

• False

• True

What is the purpose of debugging in the context of switch statements?

• To increase code complexity

• To remove all break statements

• To identify and fix logical errors

• To add more cases
