Answer Posted / vinoth sing
abstract class contain both abstract and non abstract methods
vs
interface can have only abstract methods.
a class implementing a interface itself a abstract class.
eg for interface
interface shape2d
{
double getArea();
}
class circle implements shape2d
{
int radius;
public double getArea()
{
return math.pi*r*r;
}
circle(int radius)
{
this.radius=radius;
}
class circledemo
{
public static void main (string args[])
{
circle c= new circle(10);
system.out.println(c.getArea());
}
}
