In this article, we will learn to implement binary search on char array using Java. The binary search on a char array can be implemented by using the Arrays.binarySearch() method of java.util package. This method returns the index of the required char element if it is available in the array, otherwise, it returns (-(insertion point) - 1) where the insertion point is the position at which the element would be inserted into the array. Problem Statement Write a program in Java to implement binary search on char array Input 'b', 's', 'l', 'e', 'm' Output The sorted array is: b ... Read More

To format message with long style format of date in Java, we use the MessageFormat class and the Date 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. ...

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 ...
