java enum学习和用法，代替静态常量

public class TableDictionary {
public static enum User {
TABLE("user"),
ID("id"),
NAME("name"),
AGE("age"),
USER_ACCOUNT("user_account");
private String name;
private User(String name) {
this.name = name;
}

public String getValue() {
return name;
}

public String getTableName() {
return User.values()[0].getValue();
}
}

public static enum Tags{
TABLE("tags"),
ID("id"),
TAGS_NAME("tags_name");

private String name;
private Tags(String name) {
this.name = name;
}

public String getValue() {
return name;
}

public String getTableName() {
return Tags.values()[0].getValue();
}
}
}

public class TableDictTest {

public static void main(String[] args) {
for (User user : User.values()) {
System.out.println(user);
System.out.println(user.name());
System.out.println(user.getValue());
System.out.println(user.ordinal());
System.out.println(user.toString());
System.out.println(user.getTableName());
System.out.println(user.getDeclaringClass());
System.out.println(User.valueOf("ID"));

}

}
