Mutable vs Immutable - What You Need to Know: Kotlin Fundamentals - Part 4

In this video, we explore Kotlin’s data types, how variables are declared, and the difference between mutable and immutable variables. Understanding these concepts is essential for writing efficient and type-safe Kotlin programs.

Topics covered in this video:
• Overview of Kotlin’s primary data types
• Declaring variables using var and val
• Understanding type inference in Kotlin
• How Kotlin handles type conversions and typecasting
• Using toFloat(), toInt(), and other conversion functions
• Handling runtime exceptions during type conversions
• Kotlin’s approach to primitive and wrapper types

By the end of this video, you will have a solid understanding of how Kotlin manages data types and how to effectively use them in your programs.

Stay tuned for the next video, where we will cover more advanced Kotlin concepts, including control flows, functions, classes, inheritance, and interfaces.
