The following little test throws an NPE:
public class Test {
public static void main(String[] args) {
String a = "a";
String b = null;
System.out.println(a.compareTo(b));
}
}
Yet, the Javadoc of compareTo() does not mention that the parameter cannot be null
. This is strange, since Javadocs usually mentions when parameters cannot be null
.
Is this just a glitch in the documentation or is there a more fundamental reason/twist I am missing?
