class DisplayOverloading { public void disp(char c)
{
System.out.println(c);
}
public void disp(char c, int num)
{
System.out.println(c + " "+num);
}
}
class Sample
{ public static void main(String args[]) { DisplayOverloading obj = new DisplayOverloading(); obj.disp('a'); obj.disp('a',10);
}
}
Output:
a a 10
{
System.out.println(c);
}
public void disp(char c, int num)
{
System.out.println(c + " "+num);
}
}
class Sample
{ public static void main(String args[]) { DisplayOverloading obj = new DisplayOverloading(); obj.disp('a'); obj.disp('a',10);
}

Using overloading write a program to calculate and print the area of a square, rectangle and circle.
class AreaOverload
{
double a;
void area(int side)
{
a=side*side;
System.out.println("Area of a square is :"+a);
}
void area(int len, int br)
{
a=len*br;
System.out.println("Area of a Rectangle is :"+a);
}
void area(double r)
{
a=3.14*r*r;
System.out.println("Area of a circle is :"+a);
}
public static void main(String args[ ] )
{
AreaOverload ar=new AreaOverload();
ar.area(3);
ar.area(4,6);
ar.area(3.5);
}
}
