For date formatting symbols, use the DateFormatSymbols class.Firstly, set weekdays using a string arrayString[] weekDays2 = { "", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday", "sunday" };Now, set short week days withDateFormatSymbols mySymbols = new DateFormatSymbols(); mySymbols.setShortWeekdays(weekDays2);Get the date −dateFormat = new SimpleDateFormat("EEEE, dd MMM yyyy", mySymbols); System.out.println(dateFormat.format(new Date()));The following is an example −Example Live Demoimport java.text.SimpleDateFormat; import java.text.DateFormat; import java.text.DateFormatSymbols; import java.util.Date; public class Demo {    public static void main(String[] args) {       String[] weekDays1 = { "", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday" };       String[] weekDays2 = { "", "monday", "tuesday", "wednesday", "thursday", ...

Firstly, set the time with SimpleDateFormat classFormat dateFormat = new SimpleDateFormat("h:m:s");Now, for custom format, let us fetch the hour, minute and second individuallyHour// hour dateFormat = new SimpleDateFormat("h"); String strHour = dateFormat.format(new Date()); System.out.println("Hour: "+strHour);Minute// minute dateFormat = new SimpleDateFormat("m"); String strMinute = dateFormat.format(new Date()); System.out.println("Minute: "+strMinute);Second// second dateFormat = new SimpleDateFormat("s"); String strSecond = dateFormat.format(new Date()); System.out.println("Second: "+strSecond);The following is an example −Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; public class Demo {    public static void main(String[] argv) throws Exception {       Format dateFormat = new SimpleDateFormat("h:m:s");       String str = dateFormat.format(new Date());   ...

Firstly, set the format with SimpleDateFormat classFormat dateFormat = new SimpleDateFormat("EEE, dd/MM/yyyy");Above, the “EEE” is set to display the name of the day i.e. Monday, Tuesday, Wednesday, etc.Now, to display the date −String res = dateFormat.format(new Date());The following is an example −Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; public class Demo {    public static void main(String[] argv) throws Exception {       Format dateFormat = new SimpleDateFormat("EEE, dd/MM/yyyy");       String res = dateFormat.format(new Date());       System.out.println("Date = " + res);    } }OutputDate = Thu, 22/11/2018

Firstly, set the locale −Locale[] strLocales = { US, UK, GERMANY};Now, let us set the date formats i.e. different constants −int[] constants = { SHORT, MEDIUM, LONG }; String[] str = { "SHORT", "MEDIUM", "LONG" };Loop through and get the different date formats for different countries −for (Locale country : strLocales) {    System.out.println(""+ country.getDisplayCountry() + ".....");    for (int i = 0; i < constants.length; i++) {       dateFormat = DateFormat.getDateInstance(constants[i], country);       System.out.println(str[i] + " constant = " + dateFormat.format(dt));    } }The following is an exampleExample Live Demoimport static java.text.DateFormat.*; import static java.util.Locale.*; import ...

System.out.format is used in Java to format output.Firstly, create a Calendar object −Calendar calendar = Calendar.getInstance();Now, use theDate-Time conversion characters to get the date, month and year −System.out.format("%te %tB, %tY%n", calendar, calendar, calendar);The following is the complete example −Example Live Demoimport java.util.Locale; import java.util.Calendar; public class TestFormat {    public static void main(String[] args) {       Calendar calendar = Calendar.getInstance();       System.out.format("%te %tB, %tY%n", calendar, calendar, calendar);    } }Output22 November, 2018

To format date, let us see the DateFormat.SHORT as well as DateFormat.LONG constants. Both of them displays different patterns.Here, we are formatting dates with getDateTimeInstance() method. Use the method to get a date and time format.For DateFormat.SHORT constant −DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT); System.out.println(dateFormat.format(calendar.getTime()));For DateFormat.LONG constant −dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG); System.out.println(dateFormat.format(calendar.getTime()));The following is an example −Example Live Demoimport java.text.DateFormat; import java.util.Calendar; public class Demo {    public static void main(String s[]) {       Calendar calendar = Calendar.getInstance();       // for SHORT date-time       DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT);       System.out.println(dateFormat.format(calendar.getTime()));       ...

Use the getTimeInstance() method in Java to get the time format for the locale you have set. DateFormat.FULL is a constant for full style pattern.Firstly, we will create Date objectDate dt = new Date(); DateFormat dateFormat;Let us format time for different locale with DateFormat.FULLdateFormat = DateFormat.getTimeInstance(DateFormat.FULL, Locale.CHINESE); System.out.println("Locale CHINESE = " + dateFormat.format(dt)); dateFormat = DateFormat.getTimeInstance(DateFormat.FULL, Locale.CANADA); System.out.println("Locale CANADA = " + dateFormat.format(dt)); dateFormat = DateFormat.getTimeInstance(DateFormat.FULL, Locale.ITALY); System.out.println("Locale ITALY = " + dateFormat.format(dt));The following is an example −Example Live Demoimport java.text.DateFormat; import java.util.Date; import java.util.Locale; public class Demo {    public static void main(String args[]) {       Date dt ...

Use the getTimeInstance() method in Java to get the time format for the locale you have set. DateFormat.LONG is a constant for long style pattern.Firstly, we will create Date objectDate dt = new Date(); DateFormat dateFormat;Let us format time for different locale with DateFormat.LONGdateFormat = DateFormat.getTimeInstance(DateFormat.LONG, Locale.FRENCH); System.out.println("Locale FRENCH = " + dateFormat.format(dt)); dateFormat = DateFormat.getTimeInstance(DateFormat.LONG, Locale.GERMANY); System.out.println("Locale GERMANY = " + dateFormat.format(dt)); dateFormat = DateFormat.getTimeInstance(DateFormat.LONG, Locale.CHINESE); System.out.println("Locale CHINESE = " + dateFormat.format(dt));The following is an example −Example Live Demoimport java.text.DateFormat; import java.util.Date; import java.util.Locale; public class Demo {    public static void main(String args[]) {       Date dt ...

The Float.isInfinite() method in Java returns true if this Float value is infinitely large in magnitude, else false is returned.We have the following Float valuesFloat f1 = new Float(5.0/0.0); Float f2 = new Float(10.2/0.0); Float f3 = new Float(0.0/0.0);Check with isInfinite() methodf1.isInfinite(); f2.isInfinite(); f3.isInfinite();The following is the complete example with output −Example Live Demoimport java.lang.*; public class Demo {    public static void main(String args[]) {       Float f1 = new Float(5.0/0.0);       Float f2 = new Float(10.2/0.0);       Float f3 = new Float(0.0/0.0);       System.out.println(f1.isInfinite());       System.out.println(f2.isInfinite());       System.out.println(f3.isInfinite());    } }Outputtrue true false
