NVL-ish guy in Java

I tried Oracle's NVL-like guy (transmitted) in Java. If it is non-null, it will be displayed as it is, and if it is null, a specific character string will be displayed.

Below, commons-lang3-3.5 is used.


String s = null;

String result = ObjectUtils.defaultIfNull(s, "Slimy");
System.out.println(result); //=>Slimy

If you know it, you can write it in one line. The code that actually comes up from the programmer is like this ↓.


String s = null;

//Those who are still better
if (s == null) {
    s = "Slimy";
System.out.println(s); //=>Slimy

If you carelessly like this ↓.


String s = null;

//Please stop
if (s == null) {
} else {

If this is an input value, about 100 samples like Sample3 will be mass-produced, and then it will be uncontrollable anymore. Who will review it? I want you to do your best and stop mass-producing fucking code ...
