Kotlin Data Types
Kotlin data types include Int String and Boolean with type inference.
Understanding Kotlin Data Types
Kotlin, a statically typed programming language, supports several built-in data types. These data types allow you to store and manipulate data efficiently. In Kotlin, the main data types include Int, String, and Boolean. Understanding these data types is essential for writing effective Kotlin code.
Integer Data Type (Int)
The Int data type is used to store integer values. It can hold values from -2,147,483,648 to 2,147,483,647. Kotlin provides various arithmetic operations for integers, such as addition, subtraction, multiplication, and division.
String Data Type
The String data type is used for storing sequences of characters. Strings in Kotlin are immutable, meaning once a string is created, it cannot be changed. You can perform operations like concatenation and substring extraction on strings.
Boolean Data Type
The Boolean data type represents logical values: true or false. It is commonly used in control flow statements like if and while.
Type Inference in Kotlin
Kotlin features type inference, allowing you to omit the data type declaration when it can be inferred from the context. This can make your code cleaner and more concise.
