Functional Programming


Function

Functional programming is a software development paradigm out of various available software development methodology. It is based on function which is nothing but a computation unit and it's result depends on the argument and variable defined in the scope.


  • In computer program, a functional programming treats every computation as an evaluation of mathematical functions and never use mutable data to change it's state.
  • The output value of a pure function depends on the arguments which are input to the function and will produce the same result every time for the same set of inputs. 
  • It means f(x) will always produce the same result y for same value of x.
  • A function is full of functions or declarations instead of statements.
  • Languages: Scala, Python, Erlang, Haskell etc.

Various concepts of functional programming :

  • Higher Order Functions
  • First Class Function 
  • Pure Function
  • Immutability

Null check of Object and Object Chain in Java

Image
JDK 7 and earlier: Avoid using null check in if statement. Use ternary operator for null/exist check and assign a default value before using. This will make the code clear and more understandable as comparable to using multiple if, else   statements. JDK 8 and above : Java-8 provides improved API to deal with object null check. Use isPresent() function available in Java.util.Optional interface for null check of single object. Ex – Employee employee = new Employee(); employee .setName( "Pramoda" ); // Getting optional value Optional<Employee> optionalEmployee = Optional. ofNullable ( employee ) .map(Root::getEmployee); System. out .println( "Is Employee present : + optionalemployee .isPresent()); Use Java.util.Optional functional interface for object null check and assign default value to avoid null pointer exception. Ex – Employee employee = new Employee(); employee .setNa...

Scala Functions

Function : A function is computational unit in a program. Function : To define a function specify - name, parameter, body and return type.   Functions are implicitly declared as abstract if leave off the equal sign and method body. Remove = sign if not to return any thing. A function can have named and optional parameters. Use Unit if the function does not return anything. ( Unit is equivalent to Void in java) Function definition :   def functionName ([list of parameters]) : [ return type ]             Abstract Function :   Ex - def calculation (a:Int, b:String)         Non Abstract Function :    def functionName ([list of parameters]) : [ return type ] = { }              Example -       def calculation ( a : Int, b : Int): Int = {     var sum : Int = 0     sum = a ...
