import java.util.HashMap;
import java.util.Map;

public class MpBooleanDemo {

      protected static final String UPDATE_FLG = "update_auth";
      protected static final String CREATE_FLG = "create_auth";
      protected static final String DELETE_FLG = "delete_auth";

      protected static class User {
            Map<String, Boolean> cftMp = new HashMap<String, Boolean>();

            public Map<String, Boolean> getCftMp() {
                  return cftMp;
            }

            public void setCftMp(Map<String, Boolean> cftMp) {
                  this.cftMp = cftMp;
            }
      }

      public static void main(String[] args) {
            Map<String, Boolean> cft = new HashMap<String, Boolean>();
            cft = testFunc();
            for (String tt : cft.keySet()) {
                  System.out.println("KEY: " + tt + " VALUE: " + cft.get(tt));
            }

      }

      public static Map<String, Boolean> testFunc() {
            User user = new User();
            user.getCftMp().put(UPDATE_FLG, true);
            user.getCftMp().put(CREATE_FLG, false);
            user.getCftMp().put(DELETE_FLG, true);

            return user.getCftMp();
      }
}

実行結果
KEY: delete_auth VALUE: true
KEY: update_auth VALUE: true
KEY: create_auth VALUE: false
