Variable Definition

i int = 0
f float = 0.0
b bool = false
c char = '\0'
s string = ""

Or:

i int = new int()
f float = new float()
b bool = new bool()
c char = new char()
s string = new string()
a Array<object> = new Array<object>()

Or:

i int
f float
b bool
c char
s string
a Array<object>

Constructors

package MyLib

class Point2D
  x float
  y float
  
  constructor(x float, y float)
    this.x = x
    this.y = y
  end
end

class App
  static main(args Array<string>)
    p1 Point2D(1.0, 0.0)
    p2 Point2D(0.0, 1.0)
  end
end

Nullable Variables

A nullable variable without initialization has the default value null:

i int
f float?
b bool?
c char?
s string?
a Array<object>?

Assign null later:

ni int? = 0
ns string? = "Hello"
ni = null
ns = null

Constructors

np1 Point2D? = new Point2D(1.0, 0.0)
np2 Point2D?(0.0, 1.0)
np1 = null
np2 = null
