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

Create a getValue() method in your enum, and use this instead of toString().

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

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

 public String getValue(){
  return value;
 }

And instead of:

System.out.println(Constants.YES.toString())
System.out.println(Constants.NO.toString())

(Which are also missing a semi-colon), use

System.out.println(Constants.YES.getValue());
System.out.println(Constants.NO.getValue());

Hope this solved your problem. If you do not want to create a method in your enum, you can make your value field public, but this would break encapsulation.
