public Box(double h, double w, double d)
{
// your work here
}

/**
Gets the volume of this box.
@return the volume

public double surfaceArea()
{
// your work here
}
}

Solution

class Box
{
private double height;
private double width;
private double depth;

/**
Constructs a box with a given side length.
@param sideLength the length of each side
*/   
public Box(double h, double w, double d)
{
   height = h;
   width = w;
   depth = d;
}

/**
Gets the volume of this box.
@return the volume
*/
public double volume()
{
return width * height * depth;
}

/**
Gets the surface area of this box.
@return the surface area
*/
public double surfaceArea()
{
return ((2 * height * width) + (2 * width * depth) + (2 * height * depth));
}
}

public class BoxTester
{
public static void main(String[] args)
{
Box myBox = new Box(10, 10, 10);
System.out.println((int)myBox.volume());
System.out.println(\"Expected: 1000\");
System.out.println((int)myBox.surfaceArea());
System.out.println(\"Expected: 600\");
myBox = new Box(10, 20, 30);
System.out.println((int)myBox.volume());
System.out.println(\"Expected: 6000\");
System.out.println((int)myBox.surfaceArea());
System.out.println(\"Expected: 2200\");
}
}

Output:

1000
Expected: 1000
600
Expected: 600
6000
Expected: 6000
2200
Expected: 2200
