Computer Science Write a Java program that reads a line and a line segment and then determines whether they intersect or not. When they overlap completely, consider that as intersecting. Use variables ((lp1x, lp1y), (lp2x, lp2y)) to represent a line and ((sp1x, sp1y), (sp2x, sp2y)) to represent a line segment

n this lab, you complete a prewritten Python program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of 35ドル.00. The first five letters or numbers are included in the minimum charge; there is a 4ドル charge for each additional character. If the sign is make of oak, add 20ドル.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional 15ドル charge for gold-leaf lettering.

For this task, save your work in Roman.java You surely have encountered Roman numerals: I, II, III, XXII, MCMXLVI, etc. Roman numerals are represented by repeating and combing the following seven characters: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000. To understand how they must be composed, we borrow the following excerpt from Dive Into Python: • Characters are additive. I is 1, II is 2, and III is 3. VI is 6 ("5 and 1"), VII is 7, and VIII is 8. ⚫ The tens characters (I, X, C, and M) can be repeated up to three times. At 4, you need to subtract from the next highest fives character. You can't represent 4 as IIII; instead, it is represented as IV ("1 less than 5"). The number 40 is written as XL (10 less than 50), 41 as XLI, 42 as XLII, 43 as XLIII, and then 44 as XLIV (10 less than 50, then 1 less than 5). • Similarly, at 9, you need to subtract from the next highest tens character: 8 is VIII, but 9 is IX (1 less than 10), not VIIII (since the I character cannot be...
