We saw in the previous examples that Scala expressions have a type. For instance, the value 1 is of type Int, and the expression 1+1 is also of type Int. A type is a classification of data and provides a finite or infinite set of values. An expression of a given type can take any of its provided values.
Here are a few examples of types available in Scala:
- Int provides a finite set of values, which are all the integers between -231 and 231-1.
- Boolean provides a finite set of two values: true and false.
- Double provides a finite set of values: all the 64 bits and IEEE-754 floating point numbers.
- String provides an infinite set of values: all the sequence of characters are of an arbitrary length. For instance, "Hello World" or "Scala is ...
