Complete Java SE 8 Developer Bootcamp - Conditionals-If / Else If / Else

This video tutorial explains the basics of if statements in programming, focusing on how to use Boolean values to control the flow of code. It covers writing simple if statements, using else if and else for additional conditions, and the importance of curly braces in defining code blocks. The tutorial also demonstrates running code to see the results of different conditional checks.

What is the primary purpose of an if statement in programming?

• To execute a block of code based on a condition

• To repeat a block of code multiple times

• To declare a variable

• To define a new function

Which of the following can be used as a test in an if statement?

• A character

• An integer value

• A Boolean variable

• A string value

What happens when the condition in an if statement evaluates to false?

• The code block inside the if statement is skipped

• The program terminates

• The code block inside the if statement is executed

• An error is thrown

How does an else if statement differ from an if statement?

• It executes code unconditionally

• It must always be followed by an else statement

• It provides an alternative condition to check if the previous if was false

• It can only be used once in a program

What is the role of an else statement in conditional logic?

• To execute code when all previous conditions are false

• To repeat the previous condition

• To terminate the program

• To declare a new variable

Why is it recommended to use curly braces in if statements?

• To avoid syntax errors

• To make the code run faster

• To improve code readability

• To ensure multiple statements are executed as a block

What might happen if curly braces are omitted in an if statement?

• Only the first statement after the if will be associated with the condition

• All statements will be ignored

• The program will not compile

• The program will enter an infinite loop
