Metoda Compare(char x, char y) klasy Character służy do numerycznego porównania dwóch wartości znaków. Ostateczna zwrócona wartość jest podobna do tej, którą zwróci:
mój żywy krykiet.
Character.valueoOf(x).compareTo(Character.valueOf(y))
Składnia
public static intcompare(char x, char y)
Parametr
Powyższa metoda wymaga dwóch parametrów:
- char x, który jest pierwszym znakiem do porównania
- char y, który jest drugim znakiem do porównania
Wartość zwracana
Metoda Compare(char x, char y) zwraca klasę znaków
- wartość 0 jeśli x==y
- wartość mniejsza niż 0, jeśli x
- wartość większa niż 0, jeśli x>y.
Przykład 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.'); } } }Przetestuj teraz
Wyjście:
First value is less than the second value.
