Performance

i'm using enums to replace String constants in my java app (jre 1.5).

is there a performance hit when i treat the enum as a static array of names, in a method that is called constatnly (e.g. when rendering the UI)?

my code looks a bit like this:

public String getValue(int col) {
  return ColumnValues.values()[col].toString();
}

thanks, asaf :-)
