java - I am trying to print the name of the list but somehow the reference from the arraylist is not working? -

customer class. class list arraylist of customer. have added customers list when want print customer names list null only.

import java.util.*; public class assignment1 {   public static void main(string args[])   {     list list = new list();     list.addcustomer("man");     list.addcustomer("man");     //system.out.println(list);     list.printx();     } } class customer{   public string name;   public customer(string name)   {     name = this.name;   } }  class list  {    arraylist<customer> list = new arraylist<customer>();    public void addcustomer(string name1)   {     customer x = new customer(name1);     list.add(x);     system.out.println(list.get(0));   }     public void printx()   {     for(int =0;i < list.size();i++)     {       system.out.println(list.get(i).name);     }   } } 

inside customer constructor, need set ::

this.name = name; 

and not other way round! :p

what have done right change function parameter name class parameter name null(default initialization). so, never initialize name variable of customer class, , hence null when print it.
