By default enums have their own string values, we can also assign some custom values to enums. Consider below example for that.
Examples:
enum Fruits { APPLE(“RED”), BANANA(“YELLOW”), GRAPES(“GREEN”); }
In the above example, we can see that the Fruits enumeration has three members, namely APPLE, BANANA and GRAPES, which have their own different custom values ??RED, YELLOW and GREEN.
Now to use this enum in code, there are some points we have to follow:-
// Java program to demonstrate how values can // be assigned to enums. enum TrafficSignal { // This will call enum constructor with one // String argument RED("STOP"), GREEN("GO"), ORANGE("SLOW DOWN"); // declaring private variable for getting values private String action; // getter method public String getAction() { return this.action; } // enum constructor - cannot be public or protected private TrafficSignal(String action) { this.action = action; } } // Driver code public class EnumConstructorExample { public static void main(String args[]) { // let's print name of each enum and there action // - Enum values() examples TrafficSignal[] signals = TrafficSignal.values(); for (TrafficSignal signal : signals) { // use getter method to get the value System.out.println("name : " + signal.name() + " action: " + signal.getAction() ); } } }
Output:
name : RED action: STOP name : GREEN action: GO name : ORANGE action: SLOW DOWN
