1-mjhe abstraction and interface k baare me puchna ha with code jo asani se samjh ajaye .
2- mjhe ERD ka idea dede for exp (music store ,hospital ,student ) mjhe in me se ksi ki erd banan ha to kaise banauga ?
3 - meri sql queries weak ha , me kaise in ko improve kr skta hu .

OOP k concept me jaha boht saari cheezein hoti hy wahi abstraction and interfaces b houte hy....
in dounou k darmiyan ka farq smjhne k liye ap ko thori boht OOP b aani chahiye na sirf conceptual balke programming k hisaab se b.... me abi yeh smjhta hou k ap ko OOP par command hy aur hum jo b programming karte hy us me Object ko used karte hy.... to phir kuch misaalo se aur kuch mazaah se smjhane ki koshish karte hy.... ab mazah ka naam is liye liya k agar sirf ap kaam ko foqiyat douge to hasna b bhool jaouge... aur ziyada hasne wala jese pagal kehlata hy wese na hasne wala b pagal hi smjha jata hy... :P
ooh sorry... me kahi aur nikal gaya... aap ne shayd abstract class ka pocha hy?? to abstract aur interface me kuch farq hy jo yeh hy.
1. Interface me sirf hum signature define karte hy... ( ab yeh signature kiya hy us ko u smjh lo k ... hum jo classes k andar function banane k liye jo statement used karte hy woh.... jese void Print() ya phir void Draw() ab in ko kese hum dete hy woh baad me dekhenge filhaal abi me sirf is par baat kar raha hou) is k bil muqabil Abstract class me hum instance nai bana sakte... ( me idhar smjhta hou k ap ko instance ka idea hy... is liye us hisaab se smjha raha hou instance k maine k jo hum class bana kar dete hy main program me woh.... u houta hy jese..
hum ne koi class kahi declare ki hy... Action k naam se... to hum is ko kese instance banayenge to woh main program me u instantiate hoti hy jese...... Action act= new Action(); ) ek farq to wazih hogaya par hum log interface me b instantiate nai kar sakte yeh zehen me rakhna...
chale kuch aur farq dekhte hy.....
Interface :
Interface me hum sign used karte hy.. kyun? kyun k woh jis class se inherited hoti hy woh class un tamam sign ko used karti hy... yeh hamein kiya faida deta hy?? jab hamein boht saari classes me yeh saare methods used karne ho to interfaces bana kar rakh lo...
is ki example dekhiye yaha...

is me jo interface me jo sign used kiye hy.... un tamam sign ko is k inherited function me used kiya hy ap dekh sakte hy....
2. Interface me hum method ka work nai kar sakte.
3. Interface inherit hota hy kisi class se..
4. yeh multiple inheritance ko b support karta hy..
5.. Abstract class constructor aur destructor ko support nai karta..
6. aur jo pehle b batachuka k is me hum intantiate nai bana sakte..

ab AATe hy abstract ki taraf...
1. Is me hum hum jese dousri classes me method wagera bana sakte hy is me b bana sakte hy..
2. is me hum constructor aur destructor bana sakte hy..
3. is ko b inherit karna parrta hy..
4. lekin yeh multiples inheritance ko suppport nai akrti..
5. kisi b dousri class ko hum inherit nai kar sakte is se..

is ki example yeh rahi....

is me shuru me agar ap dekho to... abstract ka keyword used kiya hy jo indicate kar raha hy k yeh abstract class hy...
aur is me jo over ride ka keyword used kiya hy woh is cheze ko indicate kar raha hy k yeh method base class me define kiya huwa hy...

NOte: mene yeh abstract class ka bataya hy abstraction kuch aur hoti hy... me smjhta hou k ap ko abstract class hi pochni thi is liye mene yeh bataya...
agar ap ko code b smjhna hy to bata dijiyega me smjhadounga...

is me kuch smjh na aaya ho to ap poch sakte hy...
baaki ki cheezein ap ko me baad me bataoungaa.......

3. Sql ki queries ko strong karne k liye me ap ko task deta hou woh karo in sha ALLAH sahih hojaegi... par pehle ap yeh batao k ap kaunsa SQL used akr rahe ho??? means Oracle ka, microsoft ka?? ya phir free ware MYSQL??

haan abstract class me hum jo b method banate hy sirf un ki sign hum mention kar sakte hy us me hum implementation nai karsakte method ki..
jese k samne screen shot me diya gaya hy ek error..



agar hum implementation karenge to error dega is ka matlab hy k us ki implimentation derived class me karna zarouri hy... warna error hi dega aur program run nai karega.. isi tarah se agar hum ne 4 abstract method banaye hy to 4rou ko hi derived class me hamein implement karna houga..
umeed hy ap ko smjh me aagaya houga... agar koi aur b query ho to ap poch sakte hy...
