If there is no index position at which they differ, then the shorter string lexicographically precedes the longer string. In this case, compareTo returns the difference of the lengths of the strings -- that is, the value: this.length()-anotherString.length() For the last case, for the lengths of the String, by …
3. How compareTo works. If the two elements (a,b) being compared are already in the right order, a.compareTo (b) will return a value that is <= 0, so nothing has to happen. If they aren't in the right order, the return value is > 0, indicating that they must be interchanged.
