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));

Either use a library that supplies a default value, or write one yourself and use it instead. — Dave Newton

I believe the only option without conditional checking is to use a ternary operator. — Collin Graves

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

I think you should use conditions, if you want to avoid 'if' clauses, use a ternary operator

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

boolean createok = users.create (String.valueOf(name) == null ? " " : String.valueOf(name), String.valueOf(desc) == null ? " " : String.valueOf(desc)) It still returned null. What am I doing wrong

null as String or null as reference ?

You can do something like this if you don't want to write if else

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