How to get value from a Java enum

Question

I have a enum which looks like:

public enum Constants{
  YES(\"y\"), NO(\"N\")
  private String value;

  Constants(String value){
    this.value = value;
           


        

Answer 1

You can also add a getter to the enumeration and simply call on it to access the instance variable:

public enum Constants{
    YES("Y"), NO("N");
    private String value;

    public String getResponse() {
        return value;
    }

    Constants(String value){
        this.value = value;
    }
}

public class TestConstants{
    public static void main(String[] args){
        System.out.println(Constants.YES.getResponse());
        System.out.println(Constants.NO.getResponse());
    }
}
