Abstract class shows kins of relationship.it is the impure
abstract.Abstract class can have method with body or
without. Abstract class can not be instantiated.e.g. Object
nahi ban sakta abstract class ka.
for example :-
abstract class Shape
{
abstract void area(); // No body compulsory to be
overriding
void show()
{
System.out.println("Shape is the show");
}
}
class circle extends Shape
{
void area()
{
}
void show()
{
System.out.println("Show the circle");
}
}
class Testabstract
{
public static void main(String ar[])
{
circle c1=new Shape(); // error object of
abstract class cannot be made
circle c2=new circle();
c2.area();
c1.show();
}
}

Answer / ramyathillainathan
We can indicate that a method must always be redefined in a sub class , thus making overriding compulsory. This is done using the modifier keyword abstract in the method definition.
example;
abstract class Shape
{
------------
------------
Abstract void draw();
------------
---------------
}
