Parameterized Method Overloading using Java

Write a program in Java to the use of Parameterized Method
Overloading.

Program:

class
Area

 {

  double CalArea(double r)

    {

      float pi=3.141f;

      return(pi*r*r);

    }

  double CalArea(double l, float b)

    {

     return (l*b);

    }

  double CalArea(float base, double height)

   {

    return(0.5*base*height);

   }

 }

class
Sk08

 {

  public static void main(String args[])

   {

    Area obj1=new Area();

    double a1= obj1.CalArea(5.5,6.5f);

    System.out.println("Area of Rectangle=
"+a1);

    Area obj2=new Area();

    double a2= obj2.CalArea(5.5f,6.5);

    System.out.println("Area of Triangle=
"+a2);

    Area obj3=new Area();

    double a3= obj3.CalArea(5.5);

    System.out.println("Area of Circle=
"+a3);

    }

 }

Compile:

D:\>javac
Sk08.java

Run:

D:\>java
Sk08

Output:

Area of
Rectangle = 35.75

Area of
Triangle = 14.625

Area of
Circle = 95.01525098085403
