Call parameterized method define in a class from the main class

Define two classes and one main class. Each of the two classes
will have parameterized method. Try to call them from main class

Program:

class
Area

 {

  double CalArea(double l, float b)

    {

     return (l*b);

    }

 }

class
Volume

 {

  double CalVol(double l, float b, double h)

    {

     return (l*b*h);

    }

 }

class
Sk09

 {

  public static void main(String args[])

   {

    Area obj1=new Area();

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

    System.out.println("Area = "+a1);

    Volume obj2=new Volume();

    double v1= obj2.CalVol(5.5,6.5f,7.5);

    System.out.println("Volume =
"+v1);

    }

 }

Compile:

D:\>javac
Sk09.java

Run:

D:\>java
Sk09

Output:

Area =
35.75

Volume =
268.125
