Guide to Data Types in Scala<\/span><\/h2>\r\n

Data Types<\/strong><\/h3>\r\n\r\n\r\n\r\n

1. Byte: It is an 8 bit signed value.<\/p>\r\n\r\n\r\n\r\n

2. Short: It is a 16 bit signed value.<\/p>\r\n\r\n\r\n\r\n

3. Int: It is a 32 bit signed value.<\/p>\r\n\r\n\r\n\r\n

4. Long: It is a 64 bit signed value.<\/p>\r\n\r\n\r\n\r\n

5. Float: It can store 32 bit of data<\/p>\r\n\r\n\r\n\r\n

6. Double: It can store 64 bit of data<\/p>\r\n\r\n\r\n\r\n

7. Char: It is a 16 bit unsigned Unicode character.<\/p>\r\n\r\n\r\n\r\n

8. String: It is a sequence of Chars<\/p>\r\n\r\n\r\n\r\n

9. Boolean: It holds either of these values the literal true or the literal false<\/p>\r\n\r\n\r\n\r\n

10. Null: It holds empty reference or null<\/p>\r\n\r\n\r\n\r\n

12. Nothing: It is the subtype of every other data type which includes no values<\/p>\r\n\r\n\r\n\r\n

13. Any: It is the super type of any type where any object is of type Any<\/p>\r\n\r\n\r\n\r\n

14. AnyRef: It is the super type of any reference type No.<\/p>\r\n\r\n\r\n\r\n

Operators<\/strong><\/h3>\r\n\r\n\r\n\r\n

An operator is a symbol that instructs the compiler to perform any mathematical or logical manipulations. Scala is rich in built-in operators and different types of operators are:<\/p>\r\n\r\n\r\n\r\n

  1. Arithmetic Operators<\/li>\r\n
  2. Relational Operators<\/li>\r\n

  5. Assignment Operators<\/li>\r\n<\/ol>\r\n<\/div>\r\n<\/div>\r\n\r\n\r\n\r\n

    Arithmetic Operators<\/strong><\/h4>\r\n\r\n\r\n\r\n

    The following are the arithmetic operators supported by Scala language.<\/p>\r\n\r\n\r\n\r\n

    \r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n
    Operator<\/strong><\/td>\r\nDescription<\/strong><\/td>\r\n<\/tr>\r\n
    +<\/td>\r\nAdds two operands<\/td>\r\n<\/tr>\r\n
    –<\/td>\r\nSubtracts second operand from the first<\/td>\r\n<\/tr>\r\n
    *<\/td>\r\nMultiplies both the operands<\/td>\r\n<\/tr>\r\n
    \/<\/td>\r\nDivides numerator by de-numerator<\/td>\r\n<\/tr>\r\n
    %<\/td>\r\nModulus operator finds the remainder after division of one number by another<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<\/figure>\r\n\r\n\r\n\r\n

    For example, if variables A=6 and B=16, then<\/p>\r\n\r\n\r\n\r\n\r\n\r\n

    Relational Operators<\/strong><\/h4>\r\n\r\n\r\n\r\n

    The following are the relational operators supported by Scala language.<\/p>\r\n\r\n\r\n\r\n

    Operator<\/td>\r\nDescription<\/td>\r\n<\/tr>\r\n
    ==<\/td>\r\nChecks if the values of two operands are equal or not, if yes then condition becomes true else False.<\/td>\r\n<\/tr>\r\n
    !=<\/td>\r\nChecks if the values of two operands are equal or not, if values are not equal then condition becomes true else False.<\/td>\r\n<\/tr>\r\n
    >\u00a0<\/td>\r\nChecks if the value of left operand is greater than the value of right operand, if yes then condition becomes true.<\/td>\r\n<\/tr>\r\n
    <\u00a0<\/td>\r\nChecks if the value of left operand is less than the value of right operand, if yes then condition becomes true.<\/td>\r\n<\/tr>\r\n
    >=<\/td>\r\nChecks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true.<\/td>\r\n<\/tr>\r\n
    <=<\/td>\r\nChecks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true.<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<\/figure>\r\n\r\n\r\n\r\n

    For example, if variables A=6 and B=16, then<\/p>\r\n\r\n\r\n\r\n\r\n\r\n

    Logical Operators<\/strong><\/h4>\r\n\r\n\r\n\r\n

    The following logical operators are supported by Scala language.<\/p>\r\n\r\n\r\n\r\n

    \r\n\r\n\r\n\r\n\r\n\r\n\r\n
    Operator<\/strong><\/td>\r\nDescription<\/strong><\/td>\r\n<\/tr>\r\n
    &&<\/td>\r\nIt is called Logical AND operator. If both the operands are non-zero then condition becomes true.<\/td>\r\n<\/tr>\r\n
    ||<\/td>\r\nIt is called Logical OR Operator. If any of the two operands is non zero then condition becomes true.<\/td>\r\n<\/tr>\r\n
    !<\/td>\r\nIt is called Logical NOT Operator. Use to reverses the logical state of its operand. If a condition is true then Logical NOT operator will make false.<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<\/figure>\r\n\r\n\r\n\r\n

    For example, if variables b1=true and b2=false, then<\/p>\r\n\r\n\r\n\r\n\r\n\r\n
