Setting an enum from user input

Your problem is that you call valueOf(...) but you discard the ContactType object that is returned by this method call.... ie, you never assign the returned object to a variable.

First get rid of your unnecessary wrapper by changing this:

public class ContactType
{
    public enum contactType
    {
        Family,
        Church,
        Friend,
        BusninessColleague,
        ServicePerson,
        Customer,
        Other
    }
}

to this:

    public enum ContactType
    {
        Family,
        Church,
        Friend,
        BusninessColleague,
        ServicePerson,
        Customer,
        Other
    }

Next use the valueOf to set a ContactType variable.

      strContactType = JOptionPane.showInputDialog ("Please enter contact type (Family, Church, BusinessColleague, ServicePerson, Customer, or Other)");
      ContactType contactType = ContactType.valueOf(strContactType);
      JOptionPane.showMessageDialog (null, strContactType);
      c1.setContactType (contactType);

Note, I would try to make it more idiot-proof by limiting the selections to a ContactType. For example:

  Object selection = JOptionPane.showInputDialog(null,
        "Choose a contact type", "Contact Type",
        JOptionPane.INFORMATION_MESSAGE, null,
        ContactType.values(), ContactType.values()[0]);

  // check that selection is not null before using
  System.out.println(selection);

调用ContactType.valueOf（strContactType）将字符串名称转换为枚举值
