Merhaba arkada\u015flar bu dersimizle beraber Java ile Nesne Tabanl\u0131 Programlama konular\u0131n\u0131 tamamlam\u0131\u015f olaca\u011f\u0131z ve ileri java programlama konular\u0131na ge\u00e7i\u015f yapaca\u011f\u0131z. Bu dersimizde s\u0131ras\u0131yla polimorfizm ve aray\u00fczler konular\u0131n\u0131 inceleyece\u011fiz.<\/p>\n\n\n\n

Polimorfizm<\/strong><\/p>\n\n\n\n

Polimorfizmi tan\u0131mlamam\u0131z gerekirse, ayn\u0131 nesne \u00fczerinden farkl\u0131 davran\u0131\u015flar elde etme ve o nesneyi farkl\u0131 bi\u00e7imlere sokma gibi bir tan\u0131m yapmam\u0131z s\u00f6z konusu olabilir.<\/p>\n\n\n\n

\u00d6rne\u011fin bir Otomobil s\u0131n\u0131f\u0131m\u0131z var ve bu Otomobil s\u0131n\u0131f\u0131n\u0131 miras alan Minibus ve BinekOtomobil adl\u0131 2 adet alt s\u0131n\u0131f\u0131m\u0131z var. Biz Otomobil nesnesi \u00fczerinden Bu alt s\u0131n\u0131flar\u0131n davran\u0131\u015flar\u0131n\u0131 elde edebiliriz.<\/p>\n\n\n\n

burada g\u00f6rd\u00fc\u011f\u00fcm\u00fcz tipik bir polimorfizm yani \u00e7ok bi\u00e7imlilik \u00f6rne\u011fidir. Bu \u015fekilde ayn\u0131 nesne ile farkl\u0131<\/strong> s\u0131n\u0131flar\u0131n nesnelerini<\/strong> elde edebiliriz.<\/p>\n\n\n

Aray\u00fczler<\/strong><\/p>\n\n\n\n

Java ile C++ dilinde olan \u00e7oklu kal\u0131t\u0131m \u00f6zelli\u011fi yoktur.\u00d6rne\u011fin bir bir k\u00f6pek hem evcil haycan hem de sokak hayvanlar\u0131 s\u0131n\u0131f\u0131na ait olabilir. Java’da ise 2 s\u0131n\u0131f\u0131 miras almak m\u00fcmk\u00fcn de\u011fildir. Peki ne yapaca\u011f\u0131z?<\/p>\n\n\n\n

Java bize Aray\u00fcz s\u0131n\u0131flar\u0131n\u0131 sunmaktad\u0131r. Bu s\u0131n\u0131flarda normal methodlar tan\u0131mlanamaz ve bu s\u0131n\u0131flar %100 soyut s\u0131n\u0131flard\u0131r. Dolay\u0131s\u0131yla abstract methodlar bulunur.<\/p>\n\n\n\n

Bu s\u0131n\u0131f\u0131 implemente eden s\u0131n\u0131f ise bu methodlar\u0131 override edip i\u00e7ini doldurur.<\/p>\n\n\n\n

}<\/strong><\/p>\n\n\n\n

burada da g\u00f6rd\u00fc\u011f\u00fcm\u00fcz gibi k\u00f6pek s\u0131n\u0131f\u0131 hem sokakhayvanlarini miras olarak alm\u0131\u015f hem de evcil hayvanlar\u0131 implemente etmi\u015f ve bu \u015fekilde \u00e7oklu kal\u0131t\u0131m \u00f6zelli\u011fi sa\u011flanm\u0131\u015f oldu.<\/p>\n\n\n\n

Benzer bir \u00f6rnek arabalar i\u00e7in de kullan\u0131labilir.Bir binek ara\u00e7 <\/strong>s\u0131n\u0131f\u0131 hem otomobil<\/strong> s\u0131n\u0131f\u0131n\u0131 miras alabilir hem de spor otomobil<\/strong> aray\u00fcz\u00fcn\u00fc implemente edebilir ve bu \u015fekilde iki s\u0131n\u0131f\u0131nda methodlar\u0131n\u0131 ve de\u011ferlerini miras olarak alm\u0131\u015f olur.<\/p>\n\n\n
