Approach1:
Using LocalDate
LocalDate
localDate = LocalDate.of(2019, 5, 23);
LocalDate
_10DaysLater = localDate.plusDays(10);
App.java
package com.sample.app; import java.io.FileNotFoundException; import java.time.LocalDate; public class App { public static void main(String args[]) throws FileNotFoundException { LocalDate localDate = LocalDate.of(2019, 5, 23); LocalDate _10DaysLater = localDate.plusDays(10); System.out.println(localDate); System.out.println(_10DaysLater); } }
Output
2019-05-23
2019-06-02
Approach
2: Using Calendar
class
Calendar
cal = Calendar.getInstance();
cal.set(2019,
5, 23);
Calendar
_10daysAfter = (Calendar) cal.clone();
_10daysAfter.add(Calendar.DATE,
10);
App.java
package com.sample.app; import java.io.FileNotFoundException; import java.text.DateFormatSymbols; import java.util.Calendar; import static java.util.Calendar.DATE; import static java.util.Calendar.HOUR; import static java.util.Calendar.MILLISECOND; import static java.util.Calendar.MINUTE; import static java.util.Calendar.MONTH; import static java.util.Calendar.SECOND; import static java.util.Calendar.YEAR; public class App { private static String getMonthFromInt(int num) { if (num < 0 || num > 11) { throw new IllegalArgumentException("Months should be in range of 0 to 11"); } DateFormatSymbols dfs = new DateFormatSymbols(); String[] months = dfs.getMonths(); return months[num]; } private static String calToString(Calendar cal) { StringBuilder builder = new StringBuilder(); builder.append(cal.get(YEAR)).append("-").append(getMonthFromInt(cal.get(MONTH))).append("-") .append(cal.get(DATE)).append(" ").append(cal.get(HOUR)).append(":").append(cal.get(MINUTE)).append(":") .append(cal.get(SECOND)).append(":").append(cal.get(MILLISECOND)); return builder.toString(); } public static void main(String args[]) throws FileNotFoundException { Calendar cal = Calendar.getInstance(); cal.set(2019, 5, 23); Calendar _10daysAfter = (Calendar) cal.clone(); _10daysAfter.add(Calendar.DATE, 10); System.out.println("cal : " + calToString(cal)); System.out.println("_10daysAfter : " + calToString(_10daysAfter)); } }
Output
cal :
2019-June-23 8:39:55:888
_10daysAfter
: 2019-July-3 8:39:55:888
