Why does the field print null?
Short answer. The parameter hides the field, so name = name assigns the parameter to itself.
What does this mean?
The current object.
Remember
| this: the current object |
| this() must come first |
You wrote name equals name. It prints null. Why? The parameter hides the field. This dot name means the field of this object. Now the name is stored. This is the current object. This with brackets must come first.
