Le comparer() la méthode est une méthode de Classe entière sous paquet java.lang . Cette méthode compare numériquement deux valeurs entières. Il renvoie le résultat en valeur entière équivalente en comparant les deux méthodes int arguments . La valeur renvoyée est identique à celle qui serait renvoyée par :

Entier.valueOf(x).compareTo(Integer.valueOf(y))

Syntaxe

Voici la déclaration de comparer() méthode:

 public static int compare(int x,int y) 

Paramètre:

Retour:

Cette méthode retournera les valeurs suivantes :

 0 = The value 0 if x == y, -1 = The value less than 0 if x y 

Des exceptions:

QUE

Version de compatibilité :

Java 1.7 et supérieur

Exemple 1

 public class IntegerCompareExample1 { public static void main(String[] args) { int num1 = 10; int num2 = 20; int num3 = 10; int num4 = 30; // as num1 less than num2, Output will be less than zero System.out.println(Integer.compare(num1, num2)); // as num1 equals num3, Output will be zero System.out.println(Integer.compare(num1, num3)); // as num4 is greater than num2, Output will be greater than zero System.out.println(Integer.compare(num4, num2)); } }
