java - Access enums through command line

enum Child {
    David(23),
    Johnson(34),
    Brackley(19);

  }

  int age;

  Child(int age) {
    this.age=age; 
  }

  void getAge() {
    return age; 

  }

  public class Test {
    public static void main(String args[]) {
    ---------------------
  }
}

If I had to enter command line arguments, for eg. if I enter java Test David

Then it should print "23".

So how can we access enums through command line.. ? what should be written in main method?

Please explain..

Answer

You need to convert the String arg from the command line to an enum value.

Child c = Child.valueOf(args[0]);
