De Compare(char x, char y)-methode van de Character-klasse wordt gebruikt om twee char-waarden numeriek te vergelijken. De uiteindelijk geretourneerde waarde is vergelijkbaar met wat zou worden geretourneerd door:
Character.valueoOf(x).compareTo(Character.valueOf(y))
Syntaxis
public static intcompare(char x, char y)
Parameter
De bovenstaande methode vereist twee parameters:
- char x, het eerste teken dat wordt vergeleken
- char y, het tweede teken dat moet worden vergeleken
Winstwaarde
De Compare(char x, char y)-methode van tekenklasse retourneert
- een waarde 0 als x==y
- een waarde kleiner dan 0 als x
- een waarde groter dan 0 als x>y.
voorbeeld 1
public class JavaCharacterCompareExample1 { public static void main(String[] args) { char firstValue = 'A'; char secondValue = 'B'; // compare the first char to the second int compareOneTwo = Character.compare(firstValue, secondValue); if (compareOneTwo> 0) { System.out.println('First value is greater than second value'); } else { System.err.println('First value is less than second value.'); } } }Test het nu
Uitgang:
First value is less than the second value.

Uitgang:
