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");
}
}

Does this compile? Can you call its methods? Do the methods print out what you expect them to?

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

I don't see any constructors. You have 3 static functions with a return type of void called Box, but no constructors.
