Dzinokosha pamusoro PLO vavo kushandisa

Vhuṱanzi

OOP - iri manyorero mapurogiramu yakaonekwa 80 remakore rechi20. Kusiyana mitauro Maitiro apo mashoko uye mirayiridzo kubudiswa kwavo kuvapo vachiravana, mune chinhu-zvinangwa zvirongwa, mashoko aya unobatanidzwa kuva chete isangano.

Basic nenheyo PLO

In chinhu-zvirongwa Software ine postulates ayo. OOP zvinotaurwa - ndiyo pfungwa yaro huru. Kune zvitatu kukosha vavo: nhaka, polymorphism uye encapsulation. Below nomumwe achaparadzwa akaongororwa zvizere. Kunyatsogona zvirongwa zviri OOP mumitauro vari kushandisa zvinhu uye makirasi. In kuchinja kubva Maitiro kwokukurukurirana kunyora bhuku remitemo chokuramba vaifarira kazhinji zvinovanetsa, zvisinei, Developers vakawanda uchaona zvakanakira akawanda PLO.

encapsulation

Encapsulation - ndiko kushandiswa date Fusion uye mirayiridzo kubudiswa yavo chete sangano - kirasi. Panguva mapurogiramu zvokunyorwa rimwe OOP mitauro pane musiyano pakati ruzivo mukati nokunze sangano. Saka kuwana date kuchengeteka uye nzira Implementation dzavo zvokunze zvinofurira Somuenzaniso, mamwe makirasi dzisina chokuita chinhu ichi. Mukati musimboti humboo huri kukunda kushamwaridzana mumwe, asi vanodzivirirwa kunze komutemo kuwana kubva kunze.

nhaka

Murayiro wechipiri OOP - nhaka - ndiwo mano imwe kirasi kushandiswa nevamwe pasina kudzokorora Implementation zvavo zvomene nzira. Nhaka hakubvisi redundancy yacho kunobva remitemo.

polymorphism

Imwe nhungamiro OOP - Polymorphism. kushandiswa kwaro zvinoreva dzokuparira zvinhu kunosiyana inosiyana kunzwisisa kunogona kuumba chete inowanikwa kuti achapindura zvakasiyana kune zviitiko uye panguva imwecheteyo kodzero kushandisa mabasa.

OOP mitauro

OOP zvinotaurwa zvinoshandiswa yakadaro rinofarirwa kupfuura zvirongwa mitauro yakaita C ++ uye Java, raikura chinokosha chikamu zvirongwa uye mafomu. Kunewo zvishoma kushandiswa OOP mitauro - ndiye Delphi, Vanoramba Pascal, Ruby nevamwe vazhinji.

PLO tsoropodzo

Pasinei Kazhinji zvakanaka mashoko vakananga nzira iyi, kazhinji OOP zvinotaurwa pachena uye achitsoropodzwa. Sezvinongoita Maitiro zvirongwa muna OOP ane zvainovhiringidzawo ayo.

Chokutanga, kunzwisisa kuchinja. Kuti tinzwisise OOP misimboti, zvinoda nguva yakawanda, zvikuru vanhu dzinoshanda chete Maitiro zvirongwa mitauro.

Chechipiri, kushaya mapepa ari kuoma nokuti haufaniri chete kutsanangura zvidzidzo uye zvinhu, asi chaizvo zviitiko Implementation yavo.

Chechitatu, kunyanya kuchinja nzira inogona kutungamirira ndechokuti bhuku remitemo uye dzakabudirira mapurogiramu chichange kukurirwa hazvina kutorwa nehama dzazvo zvikurukuru panyaya iyi, zvinhu uye zvinogonekwa. Uyezve, cherechedza inefficiency tichitarisa mundangariro yavaive. Zvisinei, zvisinei uwandu maonero yakapoteredza OOP programmers kuramba richikura uye nokukurumidza Virtual mitauro pachavo.
