Java ENUM ecxample

// Java program to demonstrate how values can

// be assigned to enums.

enum TrafficSignal

{

// This will call enum constructor with one

// String argument

RED(1,"STOP"), GREEN(2,"GO"), ORANGE(3,"SLOW DOWN");

// declaring private variable for getting values

private String action;

private Integer code;

// getter method

public String getAction()

{

return this.action;

}

public Integer getCode(){

return this.code;

}

// enum constructor - cannot be public or protected

private TrafficSignal(Integer code,String action)

{

System.out.println("code"+code+"action"+action);

this.action = action;

this.code=code;

}

// 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() +"code"+signal.getCode());
