Display minutes with SimpleDateFormat('mm') in Java
To work with SimpleDateFormat class in Java, import the following package.import java.text.SimpleDateFormat;Now, set the format with SimpleDateFormat(“mm”) to display minutes in two-digits.Format f = new SimpleDateFormat(‘”mm”);Now, get the minutes in a string.String strMinute = f.format(new Date());The following is an example −Exampleimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { // displaying current date and time Calendar cal = Calendar.getInstance(); SimpleDateFormat simpleformat = new SimpleDateFormat("dd/MMMM/yyyy hh:mm:s"); ...

Firstly, create a Formatter and Calendar object.Formatter f = new Formatter(); Calendar cal = Calendar.getInstance();Now display the current date and time. We have shown the date here in both lowercase and uppercase −f = new Formatter(); System.out.println(f.format("Date and Time (lowercase): %tc", cal)); f = new Formatter(); System.out.println(f.format("Date and Time (uppercase): %Tc", cal));The following is an example −Exampleimport java.util.Calendar; import java.util.Formatter; public class Demo { public static void main(String args[]) { Formatter f = new Formatter(); Calendar cal = Calendar.getInstance(); ...
Read MoreJava Program to display date and time information in lowercase
Firstly, create a Formatter and a Calendar object.Formatter f = new Formatter(); Calendar c = Calendar.getInstance();To display complete date and time information use the ‘c’ conversion character. However, to display it in lowercase, use ‘tc’ −f = new Formatter(); System.out.println(f.format("Date and Time (lowercase): %tc", cal));The following is an example −Exampleimport java.util.Calendar; import java.util.Formatter; public class Demo { public static void main(String args[]) { Formatter f = new Formatter(); Calendar cal = Calendar.getInstance(); System.out.println("Current date and time: "+cal.getTime()); ...

You can display timezone easily in Java using SimpleDateFormat(“z”).Firstly, to work with SimpleDateFormat class in Java, import the following package −import java.text.SimpleDateFormat;Now, set the format with SimpleDateFormat(“z”) to display timezone −Format f = new SimpleDateFormat(”z”);Now, get the timezone in a string −String strTimeZone = f.format(new Date());The following is an example −Exampleimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { // displaying current date and time Calendar cal = Calendar.getInstance(); ...
Read MoreJava Program to subtract long integers and check for overflow
To check for Long overflow, we need to check the Long.MAX_VALUE with the subtracted long result. Here, Long.MAX_VALUE is the maximum value of Long type in Java.Let us see an example wherein long integers are subtracted and if the result is still more than the Long.MAX_VALUE, then an exception is thrown −The following is an example showing how to check for Long overflow −Examplepublic class Demo { public static void main(String[] args) { long val1 = 70123; long val2 = 10567; ...
Read MoreConvert Long to numeric primitive data types in Java
Let’s say we have Long object here.Long myObj = new Long("9879");Now, if we want to convert this Long to short primitive data type. For that, use the in-built shortValue() method −// converting to short primitive types short shortObj = myObj.shortValue(); System.out.println(shortObj);In the same way convert Long to another numeric primitive data type int. For that, use the in-built intValue() method −// converting to int primitive types int intObj = myObj.intValue(); System.out.println(intObj);The following is an example wherein we convert Long to numeric primitive types short, int, float, etc −Examplepublic class Demo { public static void main(String[] args) { ...
Read MoreDisplay hour in KK (00-11) format in Java
The “KK” format in Java Date is used to display hour in 00-11.. Use SimpleDateFormat("KK") to get the same format −// displaying hour in KK format SimpleDateFormat simpleformat = new SimpleDateFormat("KK"); String strHour = simpleformat.format(new Date()); System.out.println("Hour in KK format = "+strHour);Above, we have used the SimpleDateFormat class, therefore the following package is imported −import java.text.SimpleDateFormat;The following is an example −Exampleimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { // displaying current date and time ...
