Variable

Variable

  • Copy the code to the editor:
         
var a = 10;
var b = 20.5;
var c = a + b;
  • Format the code (press <Ctrl+F5>).
    • EXPECTED RESULT: The code should be formatted
var a = 10;
var b = 20.5;
var c = a + b;

Data Types

  • Copy the code to the editor:
         
var i = 3;
var num = 3.0;

var b = true;

var c = "2".charAt(0);


var byte:Byte = 1;
var short:Short = 2;
var long:Long = 3;
var float:Float = 5.0;
var double:Double = 10.0;


var date = 3h;

var str = "Hello!";

class A{}

var a = A{};

var void = function():Void{};

var f = function(a:Number, b:String):Boolean { true };
var seqf = function(a:A[], b:String[]):Boolean[] { [] };


var seq = ["1","2","3" ];
  • Format the code (press <Ctrl+F5>).
    • EXPECTED RESULT: The code should be formatted
var i = 3;
var num = 3.0;

var b = true;

var c = "2".charAt(0);


var byte:Byte = 1;
var short:Short = 2;
var long:Long = 3;

var a = 3 on replace{
    println(a);
}

  • Copy the code to the editor:
         
var a  =  4;
var b  =  bind a with inverse;
  • Format the code (press <Ctrl+F5>).
    • EXPECTED RESULT: The code should be formatted
var a  =  4;
var b  =  bind a with inverse;
