hi all.

i am newilly joined please help me
what is the main different's for Intrface and Abstract Class

[Eyass_Loves_Java]

well....

FIRST:- the interface is 100% abstract and that means that all its methods are abstract and they are need to be overridden (all of them)
this an example of an interface:

public interface Eyass {

public abstract void setAge();
public void setHobby();
abstract void setFoto();
void setLocation();
}

in the interface all methods are public and abstract wether you declare that or not ok i mean you can cancel the declaration (public abstract).

in addition: the interface is implemented (i mean it's not inherited like the class) for exapmle :say i have this class Person

we say :

Class person implements Eyass {

// some code .....
}

SECOND:- Abstract Classes:

they are classes but with the declaration abstract which means that
we cant take an instance of the abstract class and the only way to deal with the abstract class is to inherit it by a subclass(child)

if we declare Eyass as an abstract class like:

public abstract class Eyass{

public abstract void setAge();
public void setHobby() { //some code};
abstract void setFoto();
void setLocation() { }
}
you have to know that the abstract class can have abstract methods and non-abstract methods and only the abstract methods must be overridden while the non-abstract method is free to be overridden or not.

and we dont forget the to use the abstract class we say:

class Person extends Eyass {

//some code ...

}

i hope it's useful to you and if i made any mistake i hope some developer correct it ... thanks
