Object comes out to "null"

Every time I try to print the name, it comes out to "null." Not sure how to fix it.

On line 8 of Cow.java, you have name = "Camille"; which just overwrites the parameter instead of setting the class property (leaving the property "null"). Plus, it always sets the name "Camille" instead of the argument that was given.

In the video, the code shown for that line is this.name = name; which sets the property using the parameter.

You might want to review this part of the video.
