final String TYPO_FRI = "ffri"; final String TYPO_FRIDAY = "ffriday"; After we understand how to compare aStringand anenuminstance, we’ll also discuss the common use case of these comparisons. So next, let’s see them in action. 3. Comparing a GivenStringto anenumInstance’s Name ...
int compareToIgnoreCase(String str)Compares two strings lexicographically, ignoring differences in case. Returns an integer indicating whether this string is greater than (result is > 0), equal to (result is = 0), or less than (result is < 0) the argument. ...

If your application audience is limited to people who speak English, you can probably perform string comparisons with the String.compareTo method. The String.compareTo method performs a...
