What does "Object obj: ArrayList" do in java?

Question

I have been looking at a friends java code and this came up. But im not sure what it is. Can anyone help quickly. The code is like this:

for(Customers cust: customerArrayList) {
//  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^-- fragment which I don't understand

Does it look something like `for (SomeElement oneElement : manyElements){..}`? If yes research "enhanced for loop". If no use [edit] option and provide more context (like fragment of code which contains what you are asking about). — Pshemo, Jun 21 '21 at 17:51

This is similar to following code :-

for(int i =0;i< customerArrayList.size();i++){
System.out.print(customerArrayList.get(i));
}
