Question

Use Java and creat proper classes to finish this problem

Write a class called Date that represents a date consisting of a year, month, and day. A Date object should have the following methods: public Date(int year, int month, int day) Constructs a new Date object to represent the given date. public void addDays(int days) Moves this Date object forward in time by the given number of days. public void addWeeks(int weeks) Moves this Date object forward in time by the given number of seven-day weeks. public int daysTo(Date other) Returns the number of days that this Date must be adjusted to make it equal to the given other Date. public int getDay() Returns the day value of this date; for example, for the date 2006/07/22, returns 22. public int getMonth() Returns the month value of this date; for example, for the date 2006/07/22, returns 7, public int getYear() Returns the year value of this date; for example, for the date 2006/07/22, returns 2006. public boolean isLeapYear() Returns true if the year of this date is a leap year. A leap year occurs every four years, except for multiples of 100 that are not multiples of 400. For example, 1956, 1844, 1600, and 2000 are leap years, but 1983, 2002, 1700, and 1900 are not public String toString() Returns a String representation of this date in year/month/day order, such as "2006/07/22".

Answer 1

class Date{

private int day;

private int month;

private int year;

//constructor

public Date(){

day=1;

month=1;

year=1500;

}

// parameterize constructor

public Date(int Year,int Month,int Day){

day=Day;

month=Month;

year=Year;

}

// getNumber of days in month

public int NumberOfDaysInMonth(int m){

  switch (m)

  {

  case 1:

  {

       return 31; }

  case 2:

  {

       return 28; }

  case 3:

  {

       return 31; }

  case 4:

  {

       return 30;

  }

  case 5:

  {

       return 31; }

  case 6:

  {

       return 30; }

  case 7:

  {

       return 31; }

  case 8:

  {

       return 31; }

  case 9:

  {

       return 30; }

  case 10:

  {

       return 31; }

  case 11:

  {

       return 30; }

  case 12:

  {

       return 31; }

  default:

    break;

  }

return 0;

}

// setting days

void setDay(int d){

  if (d>NumberOfDaysInMonth(getMonth()))

  {

    while (d>NumberOfDaysInMonth(getMonth()))

    {

      d = d - NumberOfDaysInMonth(getMonth());

      setMonth(getMonth() + 1);

    }

    day = d;

  }

  else if (d >= 1 && d <= NumberOfDaysInMonth(getMonth()))

  {

    day = d;

  }

  else

  {

    day = 1;

  }

}

public void setMonth(int m){

  if (m > 12)

  {

    while (m > 12)

    {

      m = m - 12;

      setYear(getYear() + 1);

    }

    month = m;

  }

  else if (m >= 1 && m <= 12)

  {

    month = m;

  }

  else

  {

    month = 1;

  }

}

public void setYear(int y){

  if (y>1500)

  {

    year = y;

  }

  else

  {

    year = 1500;

  }

}

public int getYear()

{

return year;

}

public int getMonth()

{

return month;

}

public int getDayOfMonth()

{

return day;

}

public void addDays(int numberOfDays)

{

setDay(day+numberOfDays);

}

public void addWeeks(int weeks)

{

day=day+7*weeks;

if(day>31)

{

int daydiff=day-31;

month++;

day=daydiff;

}

}

public int daysTo(Date other)

{

return other.day - this.day;

}

public String toString()

{

return ""+year+"/"+month+"/"+day;

}

public boolean isLeapYear() {

return (year % 400 == 0) || (year % 4 == 0 && year % 100 != 0);

}

}

class Main {

public static void main(String[] args) {

Date d= new Date(1956,5,1);

System.out.println("Current Day: "+d.getDayOfMonth());

System.out.println("Current Month: "+d.getMonth());

System.out.println("Current Year: "+d.getYear());

System.out.println("Current Year is leap year ? "+d.isLeapYear());

int num=40;

System.out.println("Adding "+num+" days in days");

d.addDays(40);

System.out.println(d.toString());

d.addWeeks(3);

}

}

OUTPUT:

OPENJDK Runtime Environment (build 10.C u0.18.04.4) javac -d . Main.java : java Main Current Day: 1 Current Month: 5 Current Year: 1956 Current Year is leap year ? true Adding 40 days in days 1956/6/10
