[b] [size=6]Java *** Abstract Class Vs Interface[/size][/b]




[color=#282828][font=helvetica, arial, sans-serif]inka interview loo ee question adaga ganee manam egesukoni ee kindi answer sitham ....[/font][/color]

[color=#282828][font=helvetica, arial, sans-serif]interface anteee anni methods abstract by defult ... adheee abstract class lo konni methods ee abstract migathaaa non abstract methods untayeee ani....[/font][/color]
[color=#282828][font=helvetica, arial, sans-serif]so ee answer ki mana desi gallu OK kani telodu interview chesthy they may not consider this as correct answer ....[/font][/color]

[color=#282828][font=helvetica, arial, sans-serif]so assalu interface anteee [/font][/color][b]Behavior ni define chesedhi [/b][color=#282828][font=helvetica, arial, sans-serif]anteee sub-classes of interface should behave how interface define ......[/font][/color]

[color=#282828][font=helvetica, arial, sans-serif]OKA example chusthy ....[/font][/color]

[u][b]Interface.....[/b][/u]

[b]vehicle anedhi oka interface anukuntee [/b][color=#282828][font=helvetica, arial, sans-serif]...[/font][/color]

[color=#282828][font=helvetica, arial, sans-serif]ikkada vehicle antee edinaa kavachu like bus , car , motorcycle illaaa ... so vehicle define behavior only .........like every vehicle should move when apply accelator , should stop when apply break...... but vehicle anedhi does not implement accelerator or break functionality endhukanteeee CAR ki accelator and motorcycle ki accelator different gaa untundi (car ki down lo , motorcycle ki hand place lo ila ) .....so[/font][/color][b] vehicle aneee interface accelator undali ani cheputhundi kani aaa accelator ela untundi ani cheppadu ..... [/b]

[color=#282828][font=helvetica, arial, sans-serif]who ever [/font][/color][b]implements the interface [/b][color=#282828][font=helvetica, arial, sans-serif]should implement the interface .... anteee CAR class and MOTORCYCLE class should write accelator method appudee vatini manam vehicle ani pilustham .....[/font][/color]

[color=#FF0000][font=helvetica, arial, sans-serif][b]interface only define the behavior but not how the behavior implements ... sub-class of interface should implemente the behavior[/b][/font][/color]

[u][b]Abstract Class ....[/b][/u]

[b]abstract class anedhi oka level down to interface[/b][color=#282828][font=helvetica, arial, sans-serif] .... mana example lo Car thesukunteee adhi abstract class anukovachu ... becaz CAR can be furthur LUXURY CAR and NORMAL CAR ..... but both luxury and normal car lu koni same functaionality share chesukunayeee ... like [/font][/color][b]apply break[/b][color=#282828][font=helvetica, arial, sans-serif] annapudu 2 cars should STOP ... but accelator may be diferent like luxury cars can take the accelaration 0-60mph in 3 sec but normal car can take same speed in 10 sec .....[/font][/color]

[color=#282828][font=helvetica, arial, sans-serif]so ikkada [/font][/color][b]apply break (which is common for both luxurt and normal car) andhi normal method in interface ......[/b]
[b]apply accelerator anedhi abstract method becaz can be different for luxury car and normal car [/b][color=#282828][font=helvetica, arial, sans-serif]......[/font][/color]

[color=#FF0000][font=helvetica, arial, sans-serif][b]abstract[/b][b] class can implement common behavior and leave the the un-common behavior to its sub-classs to implement [/b][/font][/color]
