<b> i called the TestBox class finalpractice01</b>

import java.io.*;

/*Question-1:
a. Define a class called Box with the following members:

Data members length, width and height
A no parameters constructor.
A constructor that takes parameters to initialize the data members
set Methods that will set the value of a particular data member to a
specific value received as a parameter.
get Methods that will return the value of a particular data member
A Volume( ) method to calculate and return the volume of a Box.

b. Define a class TestBox with a main( ) method.

In the main( ) method of TestBox, create an instances of Box using each of
the constructors (no- parameters constructor and parameters-constructor)
Use the Volume method to calculate the volume of each box.
Allow the user to input new values for the length width and height of one
of the boxes.
(Call the set Methods to assign the new values to the data members).
Call the Volume( ) method to calculate the new volume of the box.
Display the new volume of the box*/

public class finalpractice01
{
public static void main(String args[]) throws IOException
{
BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
Box firstbox = new Box();
Box secondbox = new Box(10, 10, 10);
System.out.println("This box's volume is: " + secondbox.Volume());
System.out.println("Enter new length value ===>>");
firstbox.setLength(Integer.parseInt(input.readLine()));
System.out.println("Enger new width value ===>>");
firstbox.setWidth(Integer.parseInt(input.readLine()));
System.out.println("Enter new height value ===>>");
firstbox.setHeight(Integer.parseInt(input.readLine()));
System.out.println("The new box's volume is: " + firstbox.Volume());
}

}

class Box
{
private int length;
private int width;
private int height;

public Box()
{
length = 0;
width = 0;
height = 0;
}

public Box(int l, int w, int h)
{
length = l;
width = w;
height = h;
}

public void setLength(int l)
{
length = l;
}

public void setWidth(int w)
{
width = w;
}

public void setHeight(int h)
{
height = h;
}

public int getLength()
{
return length;
}

public int getWidth()
{
return width;
}

public int getHeight()
{
return height;
}

public int Volume()
{
return length *width * height;
}
}

Maybe she got a deadline extension? :D
