Mai tarawa yana da janareta na lamba a lissafin asm (na mai haɗawa don VM na tushen tari).
A halin yanzu ina haɓaka sigar janareta don Java (JDK 1.8).

Sabuwar sigar mai tarawa tana goyan bayan aikin sigar farko na harshe kuma yana cika shi.

Sabon OOP

A cikin sabon sigar harshen, aikin da azuzuwan an sake fasalin wani bangare.
Ana iya bayyana hanyoyin ajin duka a cikin aji da kuma wajensa.
Ajin yanzu yana da bayyanannen mai gini: init.

Misali code:

...
class MyClass:
  private:
    var a, b

  public:
    init(a, b):
      $a ?= a
      $b ?= b
    end

    func Foo():
      return $a + $b   
    end
end

func MyClass::Bar(c):
  return $a + $b + c
end
...

Idan gado ya faru, to muna da damar yin kiran gada cikin sauƙi (super).

Misali code:

...
class MySecondClass(MyClass):
  public:

      $c ?= c
    end

    func Bar():
      super($c)  
    end
end
...

x ?= new MySecondClass(10, 20, 30)
println( x -> Bar() )     // 60

Ƙunƙarar wuce gona da iri kan hanyoyin aji:

...
func Polymorph::NewFoo(c):
  return $a + $b + c

x -> Foo(30)    // 60

Fakitin / wuraren suna

Dole ne yankin suna ya kasance mai tsabta!
Saboda haka, dole ne harshen ya ba da wannan dama.
