Answer / vikram
Hi Gopal, well I will explain u abstract methods in
layman's language. Sometimes, we want a method to perform
different functionalities. for eg. if suppose we have a
method dat finds d the area of geometric figures. Now every
geometric figure has different formula for calculating the
area. In dat case we go for abstract methods. where we just
declare a method by any name, in our case let it be "area
()". Now we can construct the body of this method depending
upon the type of geometric figure and the formula required
to find its area, seperately for all geopmetric figures.
But we will use the same name "area()" for all the methods
dat we define below to find the areas. I hope u got a vague
picture of abstract methods.

Answer / syamsunder
Abstract method does not contain method body it contains only method header so we can say this is an in complete method.If a class contains a abstract method declare the class as a abstract and implementation can provides method body to all the abstract methods and also we can't create an object to abstract class
