1)abstrat class is just a incomplete class mean to say you
only declare a method when some class extends this abstart
class then it adds some facility in this class when you
define the method body those inherited from the abstract
class.
2)but the fianl class you cn't able to add the new
functionality to this class because extnd the class its not
just mean to make child clss but to means to facilitate
this class with some aditive coding .so means to say that
its complete class you don't able to add new functionality
in this class and you never extends this class .

Abstract class is the one which is suppose to be extended
but
when we declare a class as final, we cannot extend it.

abstract class can not instantiate.
abstract class can not create abstract constructor or static method.abstract class must be inherited. and vice versa final class.

Answer / pallavi
An abstract class is one which can't be instantiated, as it
contains one or more abstract methods( methods that are
only declared, their implementation is left for
subclasses).An abstract class always needs to be extended
in order to be used.
A Final class is one which can't be extended/inherited.

Answer / farhad
A final class CANNOT be extended or subclassed however it can be instantiated:
final class A{
}
class B{
A a = new A(); //<<< instantiating final class A
We cannot say:
class B extends A //!!! that's a NO NO.
On the other hand abstract class can be subclassed but CANNOT be instantiated.
abstract class A{
}
class B extends A{
}

public class Test { public static void main(String[] args) { int countA = 0; int countB = 0; int countC = 0; int countD = 0; int countE = 0; int countF = 0; int countG = 0; int countH = 0; int countI = 0; int countJ = 0; int countK = 0; int countL = 0; int countM = 0; int countN = 0; int countO = 0; int countP = 0; int countQ = 0; int countR = 0; int countS = 0; int countT = 0; int countU = 0; int countV = 0; int countW = 0; int countX = 0; int countY = 0; int countZ = 0; } } Can anybody tell me any alternate solution(like loop or something) to automate this initialization process. Ex:- for(char chr='A';chr<='Z'; chr++) { (int) String "count"+chr = 0; }
