Enum ordinal() method
Get the ordinal of an enumeration constant in Java using ordinal() method in Java.
The following is an example −

enum Devices {
LAPTOP, MOBILE, TABLET, DESKTOP;
}
public static void main(String[] args) {
Devices d1, d2, d3, d4;
d1 = Devices.LAPTOP;
d2 = Devices.LAPTOP;
d3 = Devices.TABLET;
d4 = Devices.DESKTOP;
System.out.println("Ordinal Values...");
for(Devices d : Devices.values()) {
System.out.print(d+" = ");
System.out.println(d.ordinal());
}
}
}Output
Ordinal Values... LAPTOP = 0 MOBILE = 1 TABLET = 2 DESKTOP = 3
Enum equals() method
It returns true if the specified object is equal to this enum constant.
Let us see an example −
Example
public class Demo {
enum Devices {
LAPTOP, MOBILE, TABLET;
}
public static void main(String[] args) {
Devices d1, d2, d3;
d1 = Devices.LAPTOP;
d2 = Devices.LAPTOP;
d3 = Devices.TABLET;
if(d1.equals(d2))
System.out.println("Devices are same.");
