Java Programming for Complete Beginners - Java 16 - Step 10 - First Advantage of Encapsulation

Why is it important to use methods instead of exposing data directly in encapsulation?

• To make the code more complex

• To increase the speed of the program

• To allow invalid data to be set

• To prevent invalid states in objects

What is the role of methods in maintaining valid object states?

• They automatically fix all errors

• They make the code harder to read

• They provide logic to validate data

• They allow any data to be set

How can methods prevent invalid data from being set in an object?

• By allowing negative values

• By ignoring all input

• By implementing validation logic

• By setting all values to zero

What happens when you run a Java application with encapsulation?

• The application crashes

• All values are reset to default

• Invalid changes are ignored

• The application runs without any checks

What is introduced as encapsulation level one?

• Exposing all data directly

• Creating setters

• Removing all methods

• Creating getters
