Metoda compare() klase Java Long koristi se za numeričku usporedbu dva dugačka objekta.

Sintaksa:

 public static int compare(long x, long y) 

Parametar:

Gore navedena metoda sastoji se od dva parametra:

java okvir s popisom

1. Prva duga vrijednost koju treba usporediti.
2. Druga duga vrijednost koju treba usporediti.

Povratak:

Gornja metoda vraća:

1. 0 ako je x==y.
2. Vrijednost manja od 0 ako je x
3. Vrijednost veća od 0 ako je x>y.

Primjer 1

 public class JavaLongcompareExample1 { public static void main(String[] args) { Long s1 = 76l; Long s2 = 42l; int obj = Long.compare(s1, s2); if(obj==0) { System.out.println('Both the long values are same.'); } else if(obj>0) { System.out.println('The value ''+s1+'' is greater than '+s2); } else { System.out.println('The value ''+s1+'' is smaller than '+s2); } } } 

Izlaz:

 The value '76' is greater than 42
