The jednako() metoda je metoda klase Integer pod java.lang paket. Ova metoda uspoređuje vrijednost parametra s vrijednošću trenutnog cijelog broja objekt . Vraća se Booleov (Točno ili Netočno) što odgovara jednakosti ovog Integer i objekta argumenta metode. Također nadjačava metodu equals() klase Object.

Sintaksa:

Slijedi izjava od jednako() metoda:

 public boolean equals(Object obj) 

Parametar:

Povratak:

The jednako() metoda će vratiti true ako argument nije null i ako su cjelobrojni objekti isti kao objekt argumenta metode, inače će vratiti false.

Primjer 1

 public class IntegerEqualsExample1 { public static void main(String[] args) { Integer obj1 = new Integer(43); Integer obj2 = new Integer(78); System.out.print('obj1 and obj2 are equal. True or False? = '); System.out.println(obj1.equals(obj2)); obj1 = new Integer(55); obj2 = new Integer(55); System.out.print('obj1 and obj2 are equal. True or false? = '); System.out.println(obj1.equals(obj2)); } } 

Izlaz:

 obj1 and obj2 are equal. True or False? = false obj1 and obj2 are equal. True or false? = true
