Scala is a multi-paradigm programming language that combines the features of object-oriented programming and functional programming. Here are some of the basic syntax of Scala:
Define variables and constants:
Use the var keyword to define mutable variables and the val keyword to define immutable constants.
Example: Crawler IP Address
var x:int=10
val y:string="hello"
Data types: Scala provides a variety of data types, including integer, floating-point, boolean, and character.
Example: val a:int=10
val b:double=3.14
val c:boolean=true
val d:char='a'
Function definition: You can use the def keyword to define a function, and you can specify the parameters and return type.
Example: def add(x:int,y:int): int=
Control Flow Statement:
Scala supports if-else conditional statements and match-case statements.
Example: val age=20
if(age<18)else
Collections: Scala provides a wide range of collection classes, including lists, arrays, maps, and more.
Example: val list:list[int]=list(1,2,3,4,5).
val map:map[string,int]=map("a"->1,"b"->2,"c"->3)
Classes and objects: Scala is an object-oriented language where you can define classes and objects to organize.
Example: class person(name:string,age:int).
val person=new person("alice",25)
person.greet()
These are just some of the basic syntax of Scala, and there are many other features and syntax of Scala, such as pattern matching, higher-order functions, implicit transformations, etc.
