Burada Inner class'\u0131n i\u00e7indeyken Outter class'\u0131n elemanlar\u0131na eri\u015fememekteyiz. Bu sorunu \u00e7\u00f6zmek i\u00e7in kotlin'de inner<\/code> anahtar kelimesi kullan\u0131lmaktad\u0131r. Kodlar\u0131m\u0131z\u0131 a\u015fa\u011f\u0131daki gibi de\u011fi\u015ftirebilir ve sonu\u00e7lar\u0131 elde edebiliriz.<\/p>\n

Direkt olarak bir \u00f6rnek \u00fczerinde g\u00f6rd\u00fck. Peki bunu nerelerde kullanabiliriz? Mant\u0131ksal a\u00e7\u0131dan ayn\u0131 i\u015flemleri ger\u00e7ekle\u015ftiren class'lar\u0131 bir arada tutmak i\u00e7in kullan\u0131labilir ve daha kolay y\u00f6netilmesini sa\u011flayabilir. Asl\u0131nda inner class'lar Non-static nested class<\/strong> olarak isimlendirilir. Bu y\u00fczde ilk \u00f6rnekte Outter.Inner().testInner("test")<\/code> \u015feklinde eri\u015febilirken, nested class'\u0131m\u0131z\u0131 inner class yapt\u0131ktan sonra Outter<String>("test").Inner().testInner("test")<\/code> olarak eri\u015fim sa\u011flad\u0131k.<\/p>\n
