How can we compare dates in java

Question

Is it possible to compare dates in java? Any help?

Answer 1

You can refer the below code for comparing dates in java:

if(!historyDate.after(todayDate) && !futureDate.before(todayDate)) 

{
    /* historyDate <= todayDate <= futureDate */ 
}

Answer 2

You can use compareTo():

date1.compareTo(date2);

Answer 3

Date today = new Date();                   
  Date myDate = new Date(today.getYear(),today.getMonth()-1,today.getDay());
  System.out.println("My Date is"+myDate);    
  System.out.println("Today Date is"+today);
  if (today.compareTo(myDate)<0)
      System.out.println("Today Date is Lesser than my Date");
  else if (today.compareTo(myDate)>0)
      System.out.println("Today Date is Greater than my date"); 
  else
      System.out.println("Both Dates are equal"); 

Answer 4

public static String daysBetween(String day1, String day2) {
    String daysBetween = "";
    SimpleDateFormat myFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    try {
        Date d1 = myFormat.parse(day1);
        Date d2 = myFormat.parse(day2);
        long diff = d2.getTime() - d1.getTime();
        daysBetween = ""+(TimeUnit.DAYS.convert(diff, TimeUnit.MILLISECONDS));
    } catch (ParseException e) {
        e.printStackTrace();
    }
    return daysBetween;
}
