Java Comparator is one of the favourite questions in Java Interviews.
This concept looks deceptively simple, and slight variations of this could be asked in the interviews.
1) Write an AlphaNumeric Comparator in Java that sorts the given strings in the human readable
format.
e.g., file1, file2, file 3, file4, file 10
Not like the typical comparator file1, file10
2) Chained Comparator which can be used to join Multiple Comparators
3) Given a List of Employee Objects group the Objects such that all the employees are grouped by
Department and by Name.
4) Use Java 8 Style Comparators
