I am a newbie just like you, but I'll try to help:

When you iterate through your collection and print the class object
using: System.out.println(s);
It is printing the reference of the object, not the object content.
There are 2 ways to fix this:
1. Add the accessor methods to get the class properties, i.e add
getName, getAge methods to MyOwnClass; then when you iterate through
the collection, print out s.getName() and s.getAge.
2. Override the toString method in the MyOwnClass to display the class
properties:
void String toString() {
return "Name is " + name + "Age = " + age;
}
Then when you iterate through the collection, your System.out.println
(s) would display the "s" class properties.

definitely not a master!
