To format message with percentage fillers in Java, we use the MessageFormat class. The MessageFormat class gives us a way to produce concatenated messages which are not dependent on the language. The MessageFormat class extends the Serializable and Cloneable interfaces.Declaration - The java.text.MessageFormat class is declared as follows −public class MessageFormat extends FormatThe  MessageFormat.format(pattern, params) method formats the message and fills in the missing parts using the objects in the params array matching up the argument numbers and the array indices.The format method has two arguments, a pattern and an array of arguments. The pattern contains placeholder in {} curly ... Read More

In order to set the base time zone to GMT in Java, we use the setRawOffset(int offsetMillis) method. The java.util.TimeZone.setRawOffset(int offsetMillis) method set the base timezone offset to GMT.Declaration − The java.util.TimeZone.setRawOffset(int offsetMillis) method is declared as follows −public abstract void setRawOffset(int offsetMillis)where offsetMillis is the given base time zone offset to GMT.Let us set the base timezone offset to GMT in Java −Example Live Demoimport java.util.*; public class Example {    public static void main( String args[] ) {       // creating default object of TimeZone       TimeZone obj = TimeZone.getDefault();       System.out.println("Default timezone ...

To get the ID of the current timezone in Java, we use the ZoneId class that belongs to java.time package. This provides a way to work with different timezones and their IDs. In Java, the ZoneId class represents a time zone identifier, such as India/Europe. The ZoneId can be used to retrieve the unique ID of the current timezone. To Get the ID of this timezone in Java is quite easy. Let's learn the following methods: Using Zone Id Class Using Zone Id.systemDefault() Using TimeZone.getDefault().toZoneId() Using ... Read More

In order to get the default Time Zone in Java, we use the getDefault() method. The java.util.TimeZone.getDefault() method returns the default TimeZone for the particular host. The source of the default TimeZone varies with the implementation.Declaration −The java.util.TimeZone.getDefault() method is declared as follows −public static TimeZone getDefault()Let us see a program to get the default time zone in Java −Example Live Demoimport java.util.*; public class Example {    public static void main( String args[] ) {       // creating default object of TimeZone       TimeZone obj = TimeZone.getDefault();       System.out.println("Default timezone object: " + obj); ...

In order to get the IDs according to the given time zone offset in Java, we use the getAvailableIDs(int rawOffset) method. The java.util.TimeZone.getAvailableIDs(int rawOffset) method returns the available IDs according to the given time zone offset in the arguments.Declaration − The java.util.TimeZone.getAvailableIDs(int rawOffset) method is declared as follows −public static String[] getAvailableIDs(int rawOffset)where rawOffset is the given time zone GMT offset.Let us see a Java program which gets the IDs according to the given time zone offset −Example Live Demoimport java.util.*; public class Example {    public static void main(String args[]) {       // getting available supported ids for ...

To get all the IDs of the TimeZone in Java, we use the getAvailableIDs() method. The getAvailableIDs() method returns all the available IDs which are compatible.Declaration −The java.util.TimeZone.getAvailableIDs() method is declared as follows −public static String[] getAvailableIDs()Let us see a Java program which gets all the IDs of the Time Zone:Example Live Demoimport java.util.*; public class Example {    public static void main(String args[]) {       // getting available supported ids       String[] id = TimeZone.getAvailableIDs();       // printing available ids       System.out.println("The available IDs are as follows:");       for (int ...

In order to compute maximum element of ArrayList with Java Collections, we use the Collections.max() method. The java.util.Collections.max() returns the maximum element of the given collection. All elements must be mutually comparable and implement the comparable interface. They shouldn’t throw a ClassCastException.Declaration −The Collections.max() method is declared as follows −public static T max(Collection c)where c is the collection object whose maximum is to be found.Let us see a program to find the maximum element of ArrayList with Java collections −Example Live Demoimport java.util.*; public class Example {    public static void main (String[] args) {       List list ...

In order to get a copy of a TimeZone object in Java, we use the clone() method. The clone() method creates of a copy of the TimeZone.Declaration −The java.util.TimeZone.clone() method is declared as follows −public Object clone()Let us see a Java program which creates a copy of the TimeZone object using the clone() method −Example Live Demoimport java.util.*; public class Example {    public static void main( String args[] ) {       // creating object of TimeZone       TimeZone obj = TimeZone.getDefault();       System.out.println("Initial object: " + obj);       // copying the TimeZone ...
