[Solved]Converting objects into a custom class

in Programming Questions • 8 months ago

I have an ArrayList of a custom class of mine Atoms(I need it to be an ArrayList because the size will be dynamic and constantly fluxulating). But I have no idea how to convert the objects I get from ArrayList.get() back into my Atom class. I've tried typecasting by doing Atom(ArrayList.get(0)) but the compiler tells me that Atom() is a uknown function. Any Ideas?

Instead of:

Atom myAtom = Atom( myArrayList.get(0) );

Try:

Atom myAtom = (Atom) myArrayList.get(0);

Instead of:
Atom myAtom = (Atom) myArrayList.get(0);
try:
ArrayList<Atom> myArrayList = new ArrayList<Atom>();
and when using:
Atom myAtom = myArrayList.get(0);

No cast needed when you tell upfront what you will put in the list.
