DecimalFormat is a concrete subclass of NumberFormat that formats decimal numbers. Let us set DecimalFormat("0000000000E0") first.Format f = new DecimalFormat("0000000000E0");Now, we will format a number and display the result in a string using the format() method −String res = f.format(-97579.9146);Since, we have used both Format and DecimalFormat class in Java, therefore importing the following packages in a must −import java.text.DecimalFormat; import java.text.Format;The following is the complete example −Example Live Demoimport java.text.DecimalFormat; import java.text.Format; public class Demo { public static void main(String[] argv) throws Exception { Format f = new DecimalFormat("0000000000E0"); ...

The “mm” format is to format minutes i.e. 01, 02, 03, 04, etc. Here, we will use the following −SimpleDateFormat("mm");Let us see an example −// displaying minutes in mm format SimpleDateFormat simpleformat = new SimpleDateFormat("mm"); String strMinute = simpleformat.format(new Date()); System.out.println("Minutes in mm format = "+strMinute);Above, we have used the SimpleDateFormat class, therefore the following package is imported −import java.text.SimpleDateFormat;The following is an example −Example Live Demoimport 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 ...

The “K” format in Java Date is used to display hour in 0-11 in AM/PM format. Use SimpleDateFormat("K") to get the same format.// displaying hour in K format SimpleDateFormat simpleformat = new SimpleDateFormat("K"); String strHour = simpleformat.format(new Date()); System.out.println("Hour in K format = "+strHour);Above, we have used the SimpleDateFormat class, therefore the following package is imported −import java.text.SimpleDateFormat;The following is an example −Example Live Demoimport 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 ...

The “kk” format in Java Date is used to format hour in 01-24 format. 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 −Example Live Demoimport 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 ...

The “k” format in Java Date is used to format hour in 1-24 format. Use SimpleDateFormat("k") to get the same format.// displaying hour in k format simpleformat = new SimpleDateFormat("k"); String strHour = simpleformat.format(new Date()); System.out.println("Hour in k format = "+strHour);Above, we have used the SimpleDateFormat class, therefore the following package is imported.import java.text.SimpleDateFormat;The following is an example −Example Live Demoimport 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 ...

The “HH” format in Java Date is like 00, 01, 02, 03, … 23 hour. Use SimpleDateFormat("HH") to get the same format and in that way you can format hour.// displaying hour in HH format SimpleDateFormat simpleformat = new SimpleDateFormat("HH"); String strHour = simpleformat.format(new Date()); System.out.println("Hour in HH format = "+strHour);Above, we have used the SimpleDateFormat class, therefore the following package is imported.import java.text.SimpleDateFormat;The following is an example −Example Live Demoimport 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 ...

The binary representations of two numbers are anagrams if they have the same number of 0’a and 1’s. An example of this is given as follows −Number 1 = 3 Binary representation of Number 1 = 0011 Number 2 = 12 Binary representation of Number 2 = 1100The two numbers are anagram.A program that demonstrates this is given as follows −Example Live Demopublic class Example { public static void main (String[] args) { long x = 12, y = 3; if(Long.bitCount(x) == Long.bitCount(y)) ...
