Question
I have this if condition:
if (description == null || description == "")
I want to write this using equals because i get this below error:
Literal Strings should be compared using equals(), not '=='. The == and != operators compare the references of objects, not their values. Using the equals() (or equalsIgnoreCase()) method will compare the values of the Strings instead.
How can I write it? Urgent, please help as soon as anyone can?

Explanation / Answer
You have to use Objects.equals() method, it is null safe.
if (Objects.equals(description, null) || Objects.equals(description, ""))
