Question Java CodeProblem 03: Ticket prices for a tourist attractionA tourist attraction offers three types of tickets:Regular adult tickets at 3.000 BHD per person, with a reduction of 10% for group of at least five persons.Student tickets at 2.500 BHD per person.Family tickets for two adults and two or more children. The price is 7.500 BHD with an additional 1.500 BHD for each child beyond two children.Write a program that calculates the total price of tickets. The program displays a menu with three options, lets the user select option, and then asks for the number of people in the party. It should then display the total amount due.The class CMPE160_HW2_part3 contains starter code for you to complete.package CMPE160_HW2;public class CMPE160_HW2_part3 { public static void main(String[] args) { // in this main method, print the message prompting the user to input a choice. //then you will call the calculatePrice method with their input as arguments to the method. } //modify the below methods as appropriate //this method should have two parameters:  //1. the first paramets indicates the choice //2. the second paramets indicates a number. If this is a regular or student ticket, this number would represent the number of tickets. //if it is a family ticket, this would indicate the number of children static double calculatePrice() { } } Output example:This program calculates your ticket price for the tourist attraction.1. Regular ticket2. Student ticket3. Family ticket4. QuitEnter your choice (1-4): 1Enter the number of regular tickets: 8The cost for this is BHD 21.600This program calculates your ticket price for the tourist attraction.1. Regular ticket2.

Thato has given what data he needs for the course marketplace website a lot of thought. He has come up with quite a comprehensive set of business rules. Course Marketplace Business Rules: 1. Each course can belong to exactly one category, and many courses can belong to the same category. 2. The name of each category must be stored in the database. 3. The name, description, price, listing date and last updated date must be stored in the database for each course. 4. A teacher can create many courses, and each course can be created by more than one teacher. 5. The percentage that each teacher contributes to a specific course must be stored in the database. 6. The following must be stored for each teacher: name, surname, email, bank, bank account, bio, and website. 7. Each teacher can indicate that they specialise in multiple categories. And many teachers can specialise in the same category. 8. A discount can be applied to a specific course. The same course can be discounted many different times or never. 9. The from date and to date, as well as the price during the discount, needs to be stored in the database. 10. Sometimes courses are sold as part of a bundle. Many courses can be part of the same bundle, and the same course can be part of many different bundles. 11. The percentage contribution of each course to a specific bundle needs to be stored in the database. 12. The name, start date, end date and price of each bundle must be stored in the database. 13. A participant can (hopefully will!) buy many courses over time. And many participants can buy the same course. 14. The date that a participant signs up for a course must be stored in the database. 15. If a discount is active when a course is bought, the fact that a discount was applied to the purchase needs to be recorded in the database. 16. The following data must be stored for each participant: name, surname, email, bio, and website. 17. Each participant can indicate that they are interested in multiple categories, and many participants can be interested in the same category.   Draw an Entity Relationship Diagram (ERD) using Unified Modelling Language (UML) notation, representing these business rules. Your design should be at the logical level – include surrogate primary key and foreign key fields. Remember to remove any many-to-many relationships. You only need to submit the final, complete diagram. Tip: Make sure the diagram is readable in the document you submit!   Marks will be allocated as follows: Entities 11 marks Relationships with names 13 marks Multiplicities 13 marks Primary keys 5 marks Foreign keys 5 marks Other attributes 2 marks Correct UML notation 1 mark Total 50 mark

Part A The post is made of Douglas fir and has a diameter of 100 mm (Figure 1) It is subjected to the load of 20 kN and the soil provides a frictional resistance distributed around the post that is triangular along its sides that is, it varies from w=0 kN/mat y=0 m to w= 15 kN/m at y = 2 m.

a hockey puck moving at 7.0 m/s coasts to a halt in 75m on a smooth ice surface. What is the coefficient of friction between the ice and the puck?

​​​​​​​ The bar has a cross-sectional area of \( 1900 \mathrm{~mm}^{2} \) and \( E=250 \mathrm{GPa} \). (Figure 1) Determine the displacement of its end \( A \) when it is subjected to the distributed loading. Express your answer to three significant figures and include the appropriate units. Enter negative value in the case of contraction and positive value in the case of elongation. Figure 1 of 1 X Incorrect; Try Again; 4 attempts remaining
