myClass a = new myClass();
for (Object o : a.getList()) system.out.println("hi");
Should I first make a variable to hold a.getList(), or is the above code okay?

1As you can see in the duplicate, the `List`'s `Iterator` is already stored in a hidden variable. There's no need for you to store the `List` value explicitly. – Sotirios Delimanolis Jul 06 '15 at 15:17

4@RedRoboHood This is example code, which does not belong at Code Review. – Simon Forsberg Jul 06 '15 at 15:19
