java homework

Hi, i'm a student and i have a homework about java i will attach the question
to my message if u can help me in solving the problem.

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


that all if u can help me in my homework.

}there's the box class at least if i have more time I'll help you with the
main method.
you may even want to use doubles instead of int

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

import java.io.*;

public class finalpractice01

System.out.println("Enter new length value ===>>");
firstbox.setLength(Integer.parseInt(input.readLine()));

firstbox.setHeight(Integer.parseInt(input.readLine()));

}

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)
{

public void setLength(int l)
{

Hey da7id I don't think the solution is going to help her five years later lol.

Maybe she got a deadline extension? :D
