Help with Java Q

Question

Write a program with twice overloaded static method called area which returns a double value. The method should be in a separate class called CalcArea. The first overload takes in two double arguments (double width, double length) and returns the area of a rectangle area= width x length; the second overload takes only one double argument (double radius) and returns the area of a circle area = pi*radius*radius where pi = 3.1415

Call the method twice from the main class (call main class CalcAreaTest) once to calculate area of rectangle 3.0 x 4.0 and once to calculate area of circle whose radius is 3.0 units.

Use printf to format output to 2 places after decimal point

Print appropriate out put such as

The area of the rectangle is ......

The area of the circle is ...

Hint: for static method in a separate class you need to use class name such as CalcArea.area(....)

Answer 1

class CalcArea

{

protected static double Area(double width, double length)

{

return(width*length);

}

protected static double Area( double radius)

{

return(3.1415*radius*radius);

}

}

class CalcAreaMain

{

public static void main(String args[])

{

System.out.println(" The area of the rectange is " + CalcArea.Area(3.0,4.0));

System.out.println(" The area of the circle is " +CalcArea.Area(3.0));

}

}
