What is the best way to create a new list from an old one but with objects from that list that do not have the same reference

Question

For example let's say i have a Class MyObject

class MyObject{
int i;
String s;

My(int i,String s){
    this.i = i;
    this.s = s;
}
...
setters/getters/toString
}

and that i have a list with objects of that Class(i dont know if that make a different what kind of list it is but i want this to work with ObservableList)

ObservableList<MyObject> listOne = FXCollections.observableArrayList();
MyObject one = new MyObject(1,"foo");
MyObject two = new MyObject(2,"boo");

Now i want to make new ObservableList from objects of listOne but i want that new list have objects with different reference

if i make it like this

ObservableList<MyObject>listTwo=FXCollections.observableArrayList(listOne);

when i do something like this

listOne.get(0).setI(500);

It will also effect object in listTwo

What is best practice to avoid this ? How can i make new list of some list with objects of that list which are treat as different objects ?

I could do something like this

for (MyObject object : listOne) {
        MyObject cloneObject = new MyObject(object.getI(),object.getS());
        listTwo.add(cloneObject);
}

I just hope that there is a better way
