Program Plan Intro

Time calculation

Program plan:

  • • Import necessary header files.
  • • Define the class “Time”.
    • ○ Declare the necessary variables.
    • ○ Define the empty constructor “Time()”.
      • ■ Initialize the necessary variables.
    • ○ Define the parameterized constructor.
      • ■ Declare the function “setTime()”.
    • ○ Define the function “isValid()”.
      • ■ Return the value.
    • ○ Define the function “setTime()”.
      • ■ Check the necessary condition.
      • ■ Assign value to the necessary variables.
    • ○ Define the function “getTime12()”.
      • ■ Initialize the variable “response”.
      • ■ Check the necessary condition.
      • ■ Return, the value of the variable “response”.
    • ○ Define the function “getTime24()”.
      • ■ Initialize the variable “response”.
      • ■ Check the necessary condition.
      • ■ Return, the value of the variable “response”.
    • ○ Define the function “toString()”.
      • ■ Return the value.
    • ○ Define the “main()” function.
      • ■ Create object for the class “Time”.
      • ■ Print the necessary statements.
      • ■ Call the necessary methods to print the result on the screen.

Consider a class Time that represents a time of day. It has attributes for thehour and minute. The hour value ranges from 0 to 23, where the range 0 to11 represents a time before noon. The minute value ranges from 0 to 59.a. Write a default constructor that initializes the time to 0 hours, 0 minutes.b. Write a private method isValid(hour, minute) that returns true if thegiven hour and minute values are in the appropriate range.c. Write a method setTime(hour, minute) that sets the time if the givenvalues are valid.d. Write another method setTime(hour, minute, isAM) that sets the timeif the given values are valid. The given hour should be in the range 1 to 12.The parameter isAm is true if the time is an a.m. time and false otherwise.
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. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in…
Modify the Date class below by adding a new method called nextDay() that increments the Date by 1 when called and returns a new Date object.  This method should properly increment the Date across Month boundary (i.e from the last day of the month to the first day of the next month). //Date class declaration public class Date {        private int month; // 1-12        private int day; // 1-31 based on month        private int year; // any year          private static final int [] daysPerMonth =              {0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};           //constructor:  confirm proper value for month and day given the year         public Date (int month, int day, int year) {                 //check if month in range                 if (month <=0 II month > 12) {                      throw new IllegalArgumentException(                           “month (“ + month + “) must be 1-12”);                 }               //check if day in range for month              if…
