Implement logical operations in a computer program : Exploring Logical Operators – Part 2

This video tutorial introduces the switch statement in Java, explaining its syntax, usage, and associated keywords like switch, case, break, and default. It covers the rules for using switch statements, including the types of variables that can be used and the structure of case statements. The tutorial also explains the role of break and default cases, using a flow diagram for visualization. Finally, it provides practical examples of testing switch statements in Java code.

Which of the following types can be used with a switch statement in Java?

• float

• byte

• double

• boolean

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

• To exit the current case block

• To exit the current loop

• To skip to the next case

• To terminate the program

How many default cases can a switch statement have?

• One

• Two

• As many as needed

• None

In a switch statement, what happens if no case matches and there is no default case?

• An error is thrown

• The first case is executed

• The switch statement is skipped

• The program crashes

What is the role of a flow diagram in understanding switch statements?

• To show the history of switch statements

• To list all possible errors

• To replace the need for code

• To provide a visual representation of the logic
