A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. Suppose you have an application that is running in India as well as Japan. Here, you can't use the same time zone for both regions. Therefore, it is necessary to display time in different time zones. Java provides various built-in classes like TimeZone and ZoneId and methods like getTimeZone() that can help in displaying the current time in another time zone. However, before using them, you must import them into your Java program. Using getTimeZone() and setTimeZone() Methods ... Read More

In Java, we can create a date object using the calendar class, which gives us more control on date and time. We will discuss the process in this article. What is the Calendar class? In order to understand the usage of we must know what is the calendar class. The Calendar class allows us to work with date and time more easily than Date class. like, we can set specific parts of the date, like month, year, and day. For using Calendar class, import the following package. import java.util.Calendar; Now, let us create an object of Calendar class. Calendar ... Read More

To get the day of the week, use the Calendar.DAY_OF_WEEK.Firstly, let us get the current date.java.util.Date utilDate = new java.util.Date(); java.sql.Date dt = new java.sql.Date(utilDate.getTime());Now, using GregorianCalendar, set the time.java.util.GregorianCalendar cal = new java.util.GregorianCalendar(); cal.setTime(dt);The last step would display the day of the week as shown in the following example.Example Live Demoimport java.text.ParseException; public class Demo {    public static void main(String[] args) throws ParseException {       java.util.Date utilDate = new java.util.Date();       java.sql.Date dt = new java.sql.Date(utilDate.getTime());       System.out.println("Today's date: "+dt);       java.util.GregorianCalendar cal = new java.util.GregorianCalendar();       cal.setTime(dt);   ...

Import the following package to work with Date class.import java.util.Date;No create a Date object.Date d = new Date();Let us convert the current date to milliseconds.d.getTime()The following is an example.Example Live Demoimport java.util.Date; public class Demo {    public static void main(String[] args) {       Date d = new Date();       System.out.println("Date = " + d);       System.out.println("Milliseconds since January 1, 1970, 00:00:00 GMT = " + d.getTime());    } }OutputDate = Mon Nov 19 06:30:11 UTC 2018 Milliseconds since January 1, 1970, 00:00:00 GMT = 1542609011369

Firstly, create a Calendar class object.Calendar calendar = Calendar.getInstance();Now, import the following package.import java.sql.Date;Using a Date class now and creating an object would belong to the above package. Convert the current time to the java.sql.Date Object.Date sqlDate = new Date((calendar.getTime()).getTime());The following is an example.Example Live Demoimport java.util.Calendar; import java.sql.Date; import java.text.ParseException; public class Demo {    public static void main(String[] args) throws ParseException {       Calendar calendar = Calendar.getInstance();       // object       Date sqlDate = new Date((calendar.getTime()).getTime());       System.out.println(sqlDate);    } }Output2018-11-19Read More
