java - how i can name all my objectes in array of objectes with Jtextfield -

http://i.stack.imgur.com/68ou3.png have class named trader , have class named product.
task is:

the trader should buy many products (an object array of class product)

now want user enter name of product in jtextfield (using product k=new product();)
want jtextfield find corresponding object product objects (somehow using/implementing equals(k) method) , stored in array of objects has bought (product) in trader every time adds product way.

how can implemented?

you can't expect user enter variable name of object jtextfield , add object accordingly. if can reflection, not used in manner.

you can perhaps create product class name attribute within product class:

class product {     private string name;     //your other attributes here..      public product(string name){         this.name = name;     } } 

as user enters name of product textfield , click button, can add product according name such:

@override actionperformed(actionevent e){     traderlist.add(new product(txtproduct.gettext())); } 

the traderlist can arraylist stores various products. may add checks on product name before adding them list.
