A decent young man was sitting in a crowded church next to a beautiful young lady. Overwhelmed by a burning passion, he instantly fell in love with her. He immediately wanted her to be his girlfriend, but a formal proposal was impossible due to the situation they found themselves in. The urgency of the matter brought him to the following plan: politely he handed his lovely neighbour an opened Bible, the bookmark pointed at verse 2 John 1:5.

A while later she returned the Bible, referring to verse Ruth 2:10.

He offered her the Bible once more, now referring to verse 2 John 1:12.

This Bible conversation was soon followed by their marriage.

Assignment

The Bible is a bundle of various shorter books that were written separately and in different periods. They were only bound later. At the early beginning of the 13th century, all books —apart from a couple — were divided in chapters. Every chapter is about a page long. Since the middle of the 16th century, every chapter was divided into verses that were only a few lines or sentences long. Sometimes, a long sentence was divided into several verses — e.g. Ephesians 4:1-3 — and sometimes a number of shorter sentences made a single verse — e.g. Genesis 1:2. Usually, the Bible is quoted as followed: the name of the book, the serial number of the chapter and the number of the verse. This way, Genesis 3:5 refers to a section from the book Genesis, chapter 3, verse 5.

We are giving you a text file bible.txt¹, that contains the entire (English) text from the Bible in the following format:

*** Genesis ***

1:1 In the beginning God created the heaven and the earth.

1:2 And the earth was without form, and void; and darkness was upon the face of
the deep. And the Spirit of God moved upon the face of the waters.

*** Exodus ***

1:1 Now these are the names of the children of Israel, which came into Egypt;
every man and his household came with Jacob.

1:2 Reuben, Simeon, Levi, and Judah,

This text consists of a number of consecutive fragments. With this, every fragment consists of multiple consecutive lines and all fragments are separated by at least one line. Fragments that indicate a new Bible book, start and end with three stars, in between those stars is the name of the book (with an extra space before and after the name). All other fragments introduce the consecutive Bible verses. A Bible verse always starts with $$h:v$$ and a space. $$h \in \mathbb{N}_0$$ indicates the serial number of a chapter, $$v \in \mathbb{N}_0$$ indicates the serial number of a verse.

Define a class Bible which can recall Bible quotations. This class takes a text file as an argument to instantiate. This text file must contain text from the Bible, in the format given above. Furthermore, all objects should contain at least a method quotation, that takes the location of one or more consecutive Bible verses from the same chapter from the same Bible book as an argument. The method has to return the text of the verses. For the location of the Bible verses, a description is used that should have one of the following formats:

• book chapter:verse: In this case, the text from the Bible should be printed from the verse with serial number verse, from the chapter with serial number chapter, from the book with serial number book. The text from a verse is formed by putting all lines from the verse behind one another, separated by a single space. Before merging the lines, any white space before or after the line should be deleted.

• book chapter:start-stop: In this case, the text should print a number of consecutive Bible verses. All these verses come from the book named book, and from the chapter with serial number chapter, starting from the verse with serial number start and ending with the serial number stop. All lines of a verse should be merged in the same way as described in the previous item, and the successive verses should be merged into one single string, separated by a single space each time.
