Since Scala has some similarity with Java, it is no surprise that it has the same data types as in Java. Although there are a few additional data types.<\/p>\n

We cover the following sub-topics:<\/p>\n

  1. Scala Data Types<\/a><\/li>\n
  2. Literals in Scala<\/a><\/li>\n
  3. Escape Sequences<\/a><\/li>\n<\/ol>\n

    1. Scala Data Types<\/strong><\/h4>\n

    The table below gives a list of Scala data types.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

    Just like in Python, all data types in Scala are object data types<\/p>\n

    It is also good to know that that the data types in Scala are objects. Also called reference types or non-primitive types. This means that the<\/p>\n

    2. Literals in Scala<\/strong><\/h4>\n

    Literals are used to define a constant value for example ‘Kindson’, 0.023, 120.<\/p>\n

    Let’s take a look at some of the basic literals in Scala programming language.<\/p>\n

    Int Literals – These are values without a decimal point. I could be of type Long when suffixed by L or l. Otherwise it is an Int<\/p>\n

    Floating Point Literals<\/strong> – These are floating point values which maybe sometimes followed by the suffix F or\u00a0 f. When followed by a suffix, it is a Float, otherwise it is a double.<\/p>\n

    Boolean Literals<\/strong> – Boolean literals are true<\/strong> or false<\/strong> values<\/p>\n

    Symbol Literals<\/strong> – A symbol literal ‘x’ in scala represents the expression scala.Symbol(“x”)<\/p>\n

    Character Literals<\/strong> – Character literals in Scala is enclosed in single quotes. For example ‘A’, ‘2’. The character could also be an escape sequence (‘\\n’ for example) or unicode characters (‘\\u0041’) for example.<\/p>\n

    String Literals<\/strong> – Just like in Java, String literals in Scala is enclosed in double quotes.<\/p>\n

    Multi-line Strings<\/strong> – A multi-line string in Scala begins with tripple double quotes (“””) and ends with same. An example is given below:<\/p>\n

    \"\"\"this is example <\/span>\r\n of multi-line string<\/span>\r\nin scala programming.\"\"\"<\/span>\r\n<\/pre>\n
     <\/p>\n
    Null Values<\/strong> – Null value is scala is of type scala.Null. It represents a reference to a special “null” object<\/p>\n
     <\/p>\n
    3. Escape Sequences<\/strong><\/h4>\n
    An escape sequence is a sequence of characters that when used within a string, translates to another character or sequence which would otherwise be difficult to represent directly. For instance, ‘\\n’ translates a newline.<\/p>\n
    The table below provides a list of escape sequences in Scala.<\/p>\n
