(The Time class)
Design a class named Time.
The class contains:
- The data fields hour, minute, and second that represent a time.
- A no-arg constructor that creates a Time object for the current time. (The values of the data fields
will represent the current time.)
-A constructor that constructs a Time object with a specified elapsed time since midnight, January
1, 1970, in milliseconds. (The values of the data fields will represent this time.)
-A constructor that constructs a Time object with the specified hour, minute, and second.
- Three getter methods for the data fields hour, minute, and second, respectively.
-A method named setTime (long elapseTime) that sets a new time for the object using the
elapsed time. For example, if the elapsed time is 555550000 milliseconds, the hour is 10, the
minute is 19, and the second is 10.
Draw the UML diagram for the class and then implement the class.
Write a test program that creates two Time objects (using new Time (), new Time(555550000),…
Write a class, define 3 properties and 5 methods to that class.

- Bank Accounts (Use Python) Write a program that accepts bank transactions and prints out the balance of an account afterwards. PROGRAM DESIGN Create a class named bankAccount. A bank account should have the following attributes: accNumber, balance, and dateOpened. This class should also have the option to do the following transactions: deposit, withdraw and drop. Initially there is only one bankAccount active in the program, with a balance amount of 1515, and was opened back in 10/01/1987. Depositing adds to a current bankAccount’s balance, while withdrawing – does otherwise. Dropping would equate the current balance to zero. Refer to the following class diagram for more details about the current bankAccount: bankAccountaccNumber = 1balance = 1515dateOpened = "10/27/1987" deposit(dep)withdraw(wd)drop(accNumber) INPUTThe input would be a string that contains the following data: the transaction to be done (dep – for deposit, wd – for withdraw and drop – for drop), the accNumber, and…arrow_forwardReadme.md: Stars(C++) This lab exercise will practice creating objects with constructors and destructors and demonstrate when constructors and destructors are called. Star Class Create a class, Star. A Star object has two member variables: its name, and a solar radius. This class should have a constructor which takes a std::string, the name of the star, and a double, the solar radius of the star. In the constructor, the Star class should print to the terminal that the star was born. For example, if you create a Star as follows: Star my_star("Saiph", 22.2); Then the constructor should print: The star Saiph was born. In the destructor, the Star class should print to the terminal that the star was destroyed, along with the number of times the volume of the sun that that star was, formatted to two decimal places. Hint: use the following line to set the precision to 2 decimal places: std::cout << std::fixed << std::setprecision(2); For example, when my_star above has its…arrow_forward4- Is it possible to call a function from inside a function?
