6. Write a Java program to compare two files lexicographically. Go to the editor
According to Wikipedia:
In mathematics, the lexicographic or lexicographical order (also known as lexical order, dictionary order, alphabetical order or lexicographic(al) product) is a generalization of the way the alphabetical order of words is based on the alphabetical order of their component letters. This generalization consists primarily in defining a total order over the sequences (often called words in computer science) of elements of a finite totally ordered set, often called alphabet.

Java: Tips of the Day
Float vs double
Programmers often cannot select the precision they need for floating-point numbers. Float requires only 4 bytes, but it has only 7 significant digits, while Double is twice as accurate (15 digits), but twice as wasteful.
In fact, most processors are able to work with Float and Double equally effectively, so use the recommendation of Bjorn Stroustrup:
"Choosing the right accuracy in real-world problems requires a good understanding of the nature of machine computing. If you do not have it, either consult with someone, or study the problem yourself, or use double and hope for the best."
