Selenium WebDriver with Java - Basics to Advanced and Frameworks - Usage of Methods in Java

The video tutorial explains the difference between printing strings and variables in Java, highlighting the use of double quotes. It introduces methods, their return types, and the importance of methods for code reuse. The tutorial also covers placing methods outside the main block and using objects to access them.

What happens if you try to print a variable in Java without declaring it?

• It results in a compilation error.

• It prints a default value.

• It prints 'null'.

• It prints the variable name as a string.

What is the return type of a method that does not return any value?

• String

• boolean

• void

• int

What should you do if a method returns a string but is declared with a different return type?

• Change the method to return an integer.

• Change the method's return type to string.

• Add a print statement instead.

• Remove the return statement.

Why are methods used in Java?

• To increase the size of the code.

• To avoid code duplication and enhance reusability.

• To make the code run faster.

• To complicate the code structure.

What is the role of access modifiers in Java methods?

• To define the method's parameters.

• To specify the visibility of the method.

• To determine the return type of the method.

• To change the method's name.

How can you access a method defined outside the main block in Java?

• By copying the method inside the main block.

• By creating an object of the class containing the method.

• By declaring the method as static.

• By using a special keyword.

What is the consequence of writing a method inside the main block?

• The method will not be recognized by Java.

• The method will execute twice.

• The method will execute only once.

• The method will be ignored.
