String.valueOf() to return empty string instead of null

Question

I have the below method call. If name or desc is null, it uses the word null. Instead I would like an empty string.

How to achieve this as part of the method call itself. I don't want to do this outside of the method call with if conditions.

boolean creatok = users.create (String.valueOf(name), String.valueOf(desc));

Answer 1

boolean creatok = users.create (Objects.toString(name, ""), Objects.toString(desc, ""));

Answer 2

我认为您应该使用条件，如果要避免使用'if'子句，请使用三元运算符

boolean creatok = users.create(name == null? "" : String.valueOf(name), name == null? "" : String.valueOf(name));

Answer 3

如果你不想写，你可以做这样的事情

boolean creatok = users.create (name == null ? "" : name, desc == null ? "" : desc);
