How to compare a string using Unicode?
The comparison is based on the Unicode value of each character in the strings. Here, string is an object of the String class. The compareTo () method takes a single parameter. returns a negative integer if the string comes before the str argument in the dictionary order
What is the use of compare() method in StringUtils class?
The compare () method in StringUtils class is a null-safe version of the compareTo () method of String class and handles null values by considering a null value less than a non-null value. Two null values are considered equal. Furthermore, this method can be used to sort a list of Strings with null entries:
Why do I get 0 when comparing learn Java to learn Java?
When "Learn Java" is compared to "learn Java", we do not get 0. It is because compareTo () takes the letter case into consideration. If you need to compare two strings ignoring case differences, use the Java String compareToIgnoreCase () method. If you pass null to the compareTo () method, you will get an error.
