A modern programming language that makes developers happier.

kotlinlang

class Main {
  public static void main(String[] args) {
    String s3 = null + “test”;
    System.out.println(s3);
  }
}

Yeah I know. I don’t think it’s a good idea.

It seems to be inconsistent behavior for nullable types

I guess that potentially you could create an extension function for java.lang.String.valueOf:
<https://docs.oracle.com/javase/7/docs/api/java/lang/String.html#valueOf(java.lang.Object)>
that seems to be the root of that issue.
