Display time zone with SimpleDateFormat("z") in Java
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(); ...

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; ...

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) { ...

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 ...
Read MoreJava Program to get the maximum of three long values
Firstly, let us declare and initialize three long values −long val1 = 98799; long val2 = 98567; long val3 = 98768;Now, find the maximum of three long values using the following condition −// checking for maximum if (val2 > val1) { val1 = val2; } if (val3 > val1) { val1 = val3; }The following is the complete example to get the maximum value −Examplepublic class Demo { public static void main(String[] args) { long val1 = 98799; long ...
Read MoreJava program to get the minimum of three long values
Firstly, let us declare and initialize three long values.long val1 = 88799; long val2 = 98567; long val3 = 98768;Now, find the minimum of three long values using the following condition −// checking for maximum if (val2 < val1) { val1 = val2; } if (val3 < val1) { val1 = val3; }The following is the complete example to get the minimum value −Examplepublic class Demo { public static void main(String[] args) { long val1 = 88799; long val2 ...
