Ich bin mit Android Studio und ich möchte die FunktionenJava Short.ToUnsignedInt Nicht definiert
Byte.toUnsignedInt(...);
Short.toUnsignedInt(...);
verwenden, aber sie geben Compiler-Fehler, auch wenn ich sehe, dass diese Mitgliederfunktionen sind, die in der Kurz sein sollte und Byte-Klasse, aber es funktioniert nicht.
Hat jemand eine Idee?

Ich habe Java 8, aber es funktioniert immer noch nicht. Dennoch, was für eine seltsame Welt wir leben, wo niemand in der Welt von Java 1,2,3,4,5,6,7 benötigt, um ein kurzes zu einem unsigned Int bis jetzt Java 8 zu konvertieren. Das hohe und mächtige Java " Götter, "die die Sprache entworfen haben, müssen außerhalb dieses Universums existieren, wo sie keine unsignierten Daten brauchen, nur wir Sterblichen und Ruff Raff brauchen solche kleinen Dinge. Wir sollten dankbar sein, dass sie daran erinnerten, Addition und Subtraktion darin zu setzen, bevor wir zu Java 10 kamen. – programmer3
Seltsames Java kann all diese fantastischen Dinge tun, aber mit einem unsignierten Byte ist es zu viel für sie. – programmer3
Es ist nicht so, als ob eine vorzeichenlose Erweiterung von short nach int schwierig ist: 'myInt = myShort & 0xFFFF;'. 'Short.toUnsignedInt()' ist nur eine nette Bequemlichkeitsmethode. – Andreas
