The Complete Java Developer Course: From Beginner to Master - Selection Control Statements

This video tutorial covers control statements in Java, focusing on selection control statements like if, if-else, and switch. It explains how these statements work, their syntax, and their practical applications. The tutorial includes examples and a challenge to create a program using these concepts, emphasizing the importance of understanding and articulating programming constructs.

What are the three categories of control statements discussed in the lecture?

• Sequence, Selection, Repetition

• Looping, Branching, Jumping

• Initialization, Execution, Termination

• Input, Process, Output

In Java, what type of value must the condition in an if statement resolve to?

• Integer

• String

• Boolean

• Character

What is the purpose of using a scanner in Java programs?

• To compile the code

• To read user input

• To execute the program

• To debug the code

What is the significance of the curly braces in an if statement?

• They indicate the end of the program

• They define the block of code to execute

• They are optional and can be omitted

• They are used to comment out code

What is the primary difference between an if statement and an if-else statement?

• If-else can only be used with numbers, if can be used with any data type

• If-else allows for multiple conditions, if does not

• If-else provides a way to execute one block of code or another based on a condition

• If-else executes code only if the condition is false, if executes if true

What is a key feature of the switch statement in Java?

• It provides multiway selection control

• It can only handle numeric data types

• It is more flexible than if-else statements

• It does not require break statements

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

• The cases will fall through and execute sequentially

• The switch statement will terminate

• The program will crash

• The next case will not execute

How can you handle both uppercase and lowercase inputs in a switch statement?

• By using a try-catch block

• By using fall through

• By using a loop

• By using nested if statements

What is the default case in a switch statement used for?

• To execute if no other case matches

• To handle errors

• To terminate the switch statement

• To initialize variables

In the challenge exercise, what are the criteria for joining the fraternity?

• Age 20 or older and any gender

• Age over 21 and any gender

• Age 19 or older and male gender

• Age 18 or older and female gender
