Main.java uses unchecked or unsafe operations ArrayList cartItems = myCart.getItemsList();

Question

I am getting the warning Note: Main.java uses unchecked or unsafe operations. in the following code

ArrayList<Product> cartItems = myCart.getItemsList();

How to remove this warning.

Your `myCart.getItemsList` returns a raw not-parameterized `List`. You can suppress the warning by adding `@SuppressWarnings("unchecked")` just right before the assignment statement. — terrorrussia-keeps-killing, Dec 01 '20 at 06:10
@fluffy thank you so much for the quick reply it worked for me but what if I do not want to suppress it. is there any other option? — Zahid Ali, Dec 01 '20 at 06:19
Make the `getItemsList` return `ArrayList`. See more at https://stackoverflow.com/questions/2770321/what-is-a-raw-type-and-why-shouldnt-we-use-it — terrorrussia-keeps-killing, Dec 01 '20 at 06:21

Does your myCart.getItemsList() returns List or ArrayList, and does the type have parameter <Product>?
You might consider using List<Product> cartItems, which should be sufficient in most cases, and make sure myCart.getItemsList() returns List<Product>.
