Java get yesterdays date

This section illustrates you how to obtain the yesterdays date.

In the given example, we simply get the current date by using the method dateFormat.format(cal.getTime()).But on subtracting one day from the calendar by using the method cal.add(Calendar.DATE, -1), the method dateFormat.format(cal.getTime()) will displayed the yesterdays date.

cal.getTime()-This method returns the Date object representing the time value of Calendar.

Here is the code of GetYesterdayDate.java

import java.text.*;

import java.sql.Date;

import java.util.Calendar;

public class GetYesterdayDate{

public static void main(String[] args) {

Calendar cal = Calendar.getInstance();

DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");

System.out.println("Todays date is "+dateFormat.format(cal.getTime()));

cal.add(Calendar.DATE, -1);

System.out.println("Yesterdays date was "+dateFormat.format(cal.getTime()));

}

}
