The porovnať () metóda je metóda Celočíselná trieda pod balík java.lang . Táto metóda numericky porovnáva dve celočíselné hodnoty. Vráti výsledok v ekvivalentnej hodnote celého čísla porovnaním metódy dvoch int argumenty . Vrátená hodnota je identická s hodnotou, ktorú by vrátil:

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

Syntax

Nasleduje vyhlásenie o porovnať () metóda:

 public static int compare(int x,int y) 

Parameter:

Vrátenie:

Táto metóda vráti nasledujúce hodnoty:

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

Výnimky:

TO

Verzia kompatibility:

Java 1.7 a vyššie

 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)); } }
