Java Programming for Complete Beginners - Java 16 - Step 03 - List Interface - Immutability and Introduction of Implemen

This video tutorial explores the concept of immutability and mutability in programming, focusing on lists. It explains that immutable lists, created using functions like 'list of', cannot be modified after creation. In contrast, mutable lists such as ArrayList, LinkedList, and Vector allow modifications. The video demonstrates how to create and manipulate these mutable lists, including adding elements. It concludes with a brief overview of when to use each type of list and hints at further discussions on list operations in future videos.

What does it mean for a class to be immutable?

• It can only be used with primitive data types.

• Its instances cannot be modified after creation.

• It is a type of mutable class.

• Its instances can be modified after creation.

Which of the following is NOT a way to create a mutable list?

• ImmutableList

• Vector

• LinkedList

• ArrayList

Which method is used to add an element to a mutable list?

• insert()

• push()

• add()

• append()

What is a key advantage of using an ArrayList?

• It is faster for insertions at the beginning.

• It is thread-safe by default.

• It allows dynamic resizing.

• It is immutable.

What should you consider when choosing between ArrayList, LinkedList, and Vector?

• The number of elements in the list.

• The type of data being stored.

• The operations you need to perform frequently.

• The color of the list in the IDE.
