Complete Java SE 8 Developer Bootcamp - Conditionals-Swtich

The video tutorial explains the switch statement in programming, highlighting its syntax and execution flow. It discusses the importance of the 'break' statement to prevent fall-through and details the data types that can be used in switch cases. The tutorial also provides examples using char and string, emphasizing the need for compile-time constants in case labels.

What is the primary difference between a Switch statement and an if statement?

• Switch statements do not require a break statement.

• Switch statements check the value of a variable directly.

• Switch statements can only evaluate integer values.

• Switch statements evaluate boolean expressions.

What is the role of the 'break' statement in a Switch case?

• It skips the current case.

• It ends the current case and exits the Switch block.

• It starts the next case.

• It repeats the current case.

What happens if a break statement is omitted in a Switch case?

• The program will crash.

• The Switch statement will terminate immediately.

• The next case will be skipped.

• The next case will be executed regardless of its condition.

Which of the following can be used as a value in a Switch statement?

• A method call

• An integer literal

• A boolean expression

• A variable

What must be true about the values used in each case of a Switch statement?

• They must be method calls.

• They must be known at compile time.

• They must be boolean expressions.

• They must be variables.

What new feature was introduced in Java 7 regarding Switch statements?

• Switch statements can now use boolean values.

• Switch statements can now use string values.

• Switch statements can now use float values.

• Switch statements can now use double values.

How can multiple cases be handled together in a Switch statement?

• By using nested Switch statements.

• By using a default case.

• By using a loop.

• By omitting the break statement between them.
