TOPICS: Using Classes and Objects MUST BE IN JAVA. PLEASE USE COMMENTS AND WRITE THE CODE IN SIMPLEST FORM.  3. Write an application that reads the radius of a sphere then calculates and displays the circumference, volume and surface area. Use the following formulas, in which r represents the sphere’s radius. Print the output to four decimal places. Circumference = 2 π r Volume = 4/3 π r3 Surface Area = 4 π r2 Hint: Section 3.5 of the textbook describes the many methods of the Math class and how they are used. The Math class also contains pre-defined constants like π. Search on the web for how you can use these. Testing: Include test exhibits for inputs that you choose. Make sure you check the results either with a calculator or some other independent source. Hint: Try Google!

Java Questions - (Has 2 Parts). Based on each code, which answer out of the choices "A,B,C,D,E" is correct. Each question has one correct answer. Thank you.  Part 1 - 9. Given the following code, the output is the date and time of __.Calendar cal = Calendar.getInstance(); TimeZone tz = TimeZone.getTimeZone("Europe/Rome");TimeZone tz = TimeZone.getTimeZone("America/Los_Angeles");TimeZone tz = TimeZone.getTimeZone("Asia/Istanbul");System.out.println(cal.getTime()); A. the "Europe/Rome" time zone.B. the time zone is computer is currently set to use.C. the "America/Los_Angeles" time zone.D. the "Asia/Istanbul" time zone.E. All of the three listed time zones. Part 2 - 10. Given the following code, the output is the date and time of __. Calendar cal = Calendar.getInstance();TimeZone tz = TimeZone.getTimeZone("Europe/Rome");cal.setTimeZone(TimeZone.getTimeZone("America/Los_Angeles"));TimeZone tz = TimeZone.getTimeZone("Asia/Istanbul");System.out.println(cal.getTime()); A. the "Europe/Rome"…

The game of Nim starts with a random number of stones between 15 and 30. Two players alternate turns and on each turn may take either 1, 2, or 3 stones from the pile. The player forced to take the last stone loses. Create a nim application in python that allows the user to play against the computer. In this version of the game, the application generates the number of stones to begin with, the number of stones the computer takes, and the user goes first. The Nim application code should:  prevent the user and the computer from taking an illegal number of stones. For example, neither should be allowed to take three stones when there are only 1 or 2 left. include an is_valid_entry() function to check user input. include a draw_stones() function that generates a random number from 1 to 3 for the number of stones the computer draws.   include separate functions to handle the user’s turn and the computer’s turn. My problem is that the code is not outputting like it's supposed to.…
