Passing Value from Scanner Class to Class Constructor

Hi All,

I am new to this forum/java programming so I apologise in advance if I explain this incorrectly

I have a main method that takes values from the scanner and passes them to the customer object


}

When I run this code the customer object is instantiated but it is set to default field values and not to the values that are picked up by the scanner.
I have found a similar thread http://www.coderanch.com/t/408970/java/java/passing-arguments-constructor
but don't quite understand what is going on.

I would really appreciate it, if somebody could spare time to have a look and help me out

Thanks
Nigel

I have attached the associated Customer code below in case it is needed.

First, it will help if you added some code tags... like so...

Hint: take a look at the constructor of your user class...



What is it that you are attempting to do?? (hint: it is not what you think it is)


And BTW, welcome to the ranch.

Hi Henry,

Thanks for pointing me in the right direction, I changed up the constructor to use the 'this' keyword(now I reference the current object) and everything work fine.
