The usporedi s() metoda je metoda klase Integer pod java.lang paket . Ova metoda uspoređuje dva cijela broja objekti numerički. Vraća rezultat vrijednosti 0 ako je Integer jednak argumentu Integer, vrijednost manja od 0 ako je Integer manji od argument Cijeli broj i vrijednost veća od 0 ako je cijeli broj veći od argumenta cijeli broj. Ovu metodu specificira Usporedivo Sučelje .

Napomena: Ova metoda ne može uspoređivati ​​dvije različite vrste argumenata, stoga i argument i broj trebaju biti iste vrste.

Sintaksa

 public int compareTo(Integer anotherInteger) 

Parametar:

Povratak:

Ova metoda će vratiti sljedeće vrijednosti:

 0 = The value 0 if this Integer = the argument Integer, -1 = The value less than 0 if thisInteger the argument Integer
