In Java, The First National Bank of Parkville recently opened up a new “So You Want toBe a Millionaire” savings account. The new account works as follows:● The bank doubles the customer’s balance every year until the customer’sbalance reaches one million.● The customer isn’t allowed to touch the money (no deposits orwithdrawals) until the customer’s balance reaches one million.● If the customer dies before becoming a millionaire, the bank keeps thecustomer’s balance.Note: Customers close to $1,000,000 tend to get “accidentally” run over in thebank’s parking lot.Write a program that prompts the user for a starting balance and then prints thenumber of years it takes to reach $100,000 and the number of years it takes toreach $1,000,000.  Sample session:Enter starting balance: 10000It takes 4 years to reach $100,000.It takes 7 years to reach $1,000,000.

Help with Java Programming  Create a program that simulates a meeting reservation system. This project is broken up into 4 parts. Part 1: Basic requirements: 1. The program shall allow the user to select from the following options: a. Create a new meeting b. Show meetings on the calendar c. Clear all meetings 2. Each meeting has a subject, start day/time and end day/time a. Subject is a short text description of the meeting b. Day is a date that contains month, day, and year c. Meeting times need only deal with hour and minute 3. When the user wants to create a new meeting, the program asks for the subject, start and end day/times for it and adds it to the calendar a. For the basic requirements, meetings are not allowed to overlap. If a meeting the user wants to schedule overlaps with an existing meeting, the program presents an error message showing which meeting the one the user wants to schedule overlaps with 4. When the user wants to show all meetings for the week, the report…

JAVA. THIS IS A PROGRAMMING ASSIGNMENT NOT A WRITING ASSIGNMENT IF YOU ANSWERED BEFORE DO NOT ANSWER AGAIN PLEASE DO NOT PASTE A PAPER     Design a class to store the following information about computer scientists⦁ Name⦁ Research area(s)⦁ Major contribution A scientist may have more than one area of research.⦁ Implement the usual setters and getters methods ⦁ Implement a method that takes a research area as an input and return thenames of scientists associated with that area ⦁ Implement a method that takes a word as an input and return the names ofscientists whose contribution mention that word Next, perform desktop research to find at least five prominent black computerscientists, with their research area(s) and major contribution, and store this data intoobjects of the class you designed. You can just hardcode this data. No user input needed.Define JUnit tests to check your research area and contribution search methods.

Hello! I am working my way through this problem for my Introduction to Java Programming Course. I think I understand the majority of it but I am have a very hard time understanding and developing the bounding box methods. I have developed the Point, Shape, Rectangle, Triangle and Circle classes but I am lost on how to calculate the bounding box coordinates for each of the hierarchy shapes. If someone would be kind enough to walk me through and explain this program, I would greatly appreciate it. Thank you kindly! Problem #5: Create a Point class to hold x and y values for a point. Create methods show(), add() and subtract() to display the Point x and y values, and add and subtract point coordinates. Hint: Keep x and y separate in the calculation. Create another class Shape, which will form the basis of a set of shapes. The Shape class will contain default functions to calculate area and circumference of the shape, and provide the coordinates (Points) of a rectangle that encloses the…
