Consider the following class definition.public class Gadget{private static int status = 0;public Gadget (){status - 10;public static void setstatus (int s){statusThe following code segment appears in a method in a class other than Gadget.Gadget a = new Gadget () ;Gadget.setstatus(3);Gadget b = new Gadget () ;Which of the following best describes the behavior of the code segment?a. The code segment does not compile because the setstatus method should be called on anobject of the class Gadget, not on the class itself.b. The code segment creates two Gadget objects a and b. The class Gadget's static variable statusis set to 10, then to 3, and then back to 10.c. The code segment creates two Gadget objects a and b. After executing the code segment, theobject a has a status value of 3 and the object b has a status value of 3.d. The code segment creates two Gadget objects a and b. After executing the code segment, theobject a has a status value of 3 and the object b has a status value of 10.e. The code segment does not compile because the static variable status is not properly initialized

1/ Write a BankAccountTester class whose main method constructs a bank account, deposits $1,000, withdraws $500, withdraws another $400, and then prints the remaining balance. Also print the expected result 2/ Implement a class Employee. An employee has a name (a string) and a salary (a double). Provide a constructor with two arguments public Employee(String employeeName, double currentSalary) and methods public String getName() public double getSalary() public void raiseSalary(double byPercent) These methods return the name and salary, and raise the employee's salary by a certain percentage. Sample usage: Employee harry = new Employee("Hacker, Harry", 50000); harry.raiseSalary(10); // Harry gets a 10 percent raise Supply an EmployeeTester class that tests all methods. 3/Implement a class Car with the following properties.
