machanla mata Abstract vs. Encapsulation eke wenasa poddak hodata pehedili karapanko net eke beluwata wedune ne..dekema nikan ekama de wagene wenne

Abstraction waladi - Abstract methods, class haa interface gannawa
Encapsulation waladi - setters and getters baawitha wenawa

eth wenne ekama widiyata implementation hiding da

hodata pehedili karanna danna kenek..

abstraction waladi karanne programme eke complexity eka adu karanna object wala thiyana features walin wadagathma saha awashyama features witharak use karala application eka hadana eka

encapsulation waladi karanne programme ekedi api use karapu features walin programme eke internal structure ekata loku balapamak karana features galapena widihata anith class walin hide karala thiyana eka. access identifiers use karala thama me wade karanne.

Abstraction and encapsulation kiyanne lagin wath yana dewal newei machan.

Abstraction walin wenne methods and properties hide karana eka newei. Interface ekak nam implement karanna one aniwa interface eke specs follow karanna one.
Abstract methods walinuth wenne subclass walata structure ekak dena eka.

Encapsulation kiyanne properties and methods wala access restrict karana eka. Eken puluwan subclass ekakata methods and properties access karanna puluwanda kiyana eka specify karanna.

Encapsulation godak wadagath wenne api library ekak kiyanakota. Public access karanna bari onema property/method ekak developer ta one widihata refactor karanna puluwan.

machan oka athatama barapathalava hithanna epa.. ova concepts withrai.. interview ekakata yanavanam nikan definition ekai example ekakui katapadam karagena giyanam athi..
p.s: matath haritata mathaka na me dekata explanation eka..

You can never be a good SE without these machan.

Abstraction eken wenne Unreliable data hide karanawa.but ee data thiyenawa as a example ubalai gedara wiring karanawa kiyala hitthahanko but ubata eeke wire cut karanne kohomada,wire walata yana diga wedak naa ne consumer ekenk widiyata ubata oona ookata related features witharai ne eg. Bulbs ,Fans anna eeka.

Thawa example ekak kiwwoth car ekak gena hithapan ooke monawada thiyenne,Car name, color , steering, gear, rear view mirror, brakes, silencer, exhaust system, diesal engine, car battery, car engine oya tika ne thiyenne,

den hitapan Car rider kenekge patten uuta monawada oona kiyala denaganna,
1. Name of Car
2. Color of Car
3. Steering
4. Rear View Mirror
5. Brakes
6. Gear

as a Car rider uuta dena ganna oona naththe(or etharam awashya nowanne ) monawada kiyala balapan,
1. Internal Details of a Car
2. Car Engine
3. Diesal Engine
4. Exhaust System
5. Silencer

den mee code eka balapan,

public class Car

private string _nameofcar = "My Car";
private string _colorofcar = "Red";

public string NameofCar

set

_nameofcar = value;
}
get

return _nameofcar;
}
}

public string ColorofCar

set

_colorofcar = value;
}
get

return _colorofcar;
}
}

public void Steering()

Console.WriteLine("Streering of Car");
}

public void RearViewMirror()

Console.WriteLine("RearViewMirror of Car");
}

public void Brakes()

Console.WriteLine("Brakes of Car");
}
public void Gear()

Console.WriteLine("Gear of Car");
}


private void InternalDetailsofCar()

Console.WriteLine("InternalDetailsofCar of Car");
}



Mee code eke necessary methods and properties PUBLIC kiyana keywork eken expose karala thiyenawa,Unnecessary methods and properties private walin hide karala thiyenawa..

Therunada manda...

concepts apply karanna danagathama athine bn.. bt u r correct.. i knw

I didn't mean any offense machan.
I took a visit to a huge (that puts Virtuasa to shame) software firm, and everyone applies OOP concepts without even knowing. They never keep shouting the Concepts but they know the practical use

This is encapsulation machan.
