Thread: not sure if my code is right, if it is not sure how to code Test box.

first, this is my homework or project for class. I don't ask anyone to do it for me, I just want help, not sure I really understand what I'm doing.

I have to make a class, Box, that accepts 3 ints for length, width and height. 3 constructors for 1, 2 or 3 ints. if 1 output a line with length x was created, if 2 a rectangle with lengths and width y created, etc. I was just wondering if I did this right, I'm stuck trying to write BoxTest to check that it works, but here is what I have so far.
Thank you

//This is the beginning of the Box class
public class Box
{
private int length;
private int width;
private int height;

public static void Box(int x)
{
int length = x;
int width = 0;
int height = 0;
System.out.print("Line created");
}
public static void Box(int x, int y)
{
int length = x;
int width = y;
int height = 0;
System.out.print("Rectangle created");
}
public static void Box(int x, int y, int z)
{
int length = x;
int width = y;
int height = z;
System.out.print("Box created");
}
}

it does compile, I'm not sure because I'm really confused with java and i don't think I even need those println statements. this class defines box and the test box i need to write creates 3 instances, 1 for each constructor
