Scala Data Types
Jakob Jenkov |
Scala comes with the following built-in data types which you can use for your Scala variables:
Type | Value Space |
Boolean | true or false |
Byte | 8 bit signed value |
Short | 16 bit signed value |
Char | 16 bit unsigned Unicode character |
Int | 32 bit signed value |
Long | 64 bit signed value |
Float | 32 bit IEEE 754 single-precision float |
Double | 64 bit IEEE 754 double-precision float |
String | A sequence of characters |
Here is an example of how to declare a variable to be of a certain type:
var myInt : Int var myString : String
All Data Types are Objects
All the data types listed above are objects. There are no primitive types
like in Java. This means that you can call methods on an Int
,
Long
etc. if you want to.
