String’s compareTo method compares two String lexicographically. Both String get converted to unicode value and then compares.
When you run above program, you will get below output:
If you call str1.compareTo(str2)
then if it returns
positive number : str1 is greater than str2
0: str1 is equal to str2
negative number : str1 is smaller than str2
