This prints out as follows: Mailing list is: Address@f56cf041 Address@f574f041 Address@f624f041 Address@f634f041 Why does it not print out the address contained within the element? It prints out the actual elements, if I use simple objects such as Strings such as the following example:
Output of this is as follows: C U C K O O I would have expected the 1st MailingList program to print out the actual addresses(although not formatted properly). Can anyone please explain?

That's because your address class does not override toString() method of Object Class.The toString method for Object class returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. For example - Address@f56cf041

When you output a class, the program actually calls MyClass.toString(). The Object class defines toString as returning ClassName@hashcode. In order to output the Address correctly add the following method:
Feel free to change the code to produce whatever formatting you'd like. -Stu
use getter and setter for accessing the private data member of a class.
then use foreach loop to display
You realise this is an 11‑year old thread? That technique would work well, however.
You should always use the code button. I thought of editing your post with the code button because the code looks much better, but you hadn't indented the code. We have some suggestions about indenting here. If you are quick, you can use the button to indent your code and add code tags for yourself.
