I'm not sure how the following method is called in Java? [duplicate]-CodePudding

I was looking at some code and I saw the following method.

ArrayList<Invoices> a = createData();

private static ArrayList<Invoices> createData() throws ParseException {
        ArrayList<Invoices> a = new ArrayList();
        a.add(new Invoices(1, "Book"));
        a.add(new Invoices(2, "Table"));
        a.add(new Invoices(3, "Lamp"));
        return a;

I understand what the method itself does but I'm confused on how it's called. Why is there the name of the Array list in the method declaration header?

 ArrayList<Invoices>

This is the type of the value returne by the method.

ArrayList<Invoices>

It is returned value by function createData()
