Format integer values with java.text.DecimalFormat
Here, we are using the DecimalFormat class in Java to format integer value, which is the java.text.DecimalFormat package.Let us take the following format: DecimalFormat("0.######E0") and use the format() method for this purpose −new DecimalFormat("0.#####E0").format(5089) new DecimalFormat("0.#####E0").format(608)Since, we have used DecimalFormat class in Java, therefore importing the following package in a must −import java.text.DecimalFormat;The following is an example −Exampleimport java.text.DecimalFormat; public class Demo { public static void main(String[] argv) throws Exception { System.out.println(new DecimalFormat("0.#####E0").format(387979)); System.out.println(new DecimalFormat("0.#####E0").format(29797)); System.out.println(new DecimalFormat("0.#####E0").format(49788)); ...

The following format displays time from −hh:mm:ssThe following format displays time with AM/ PM marker −hh:mm:ss aHere, we are using the SimpleDateFormat class to display date and time. Let us set it for the format we want i.e time and AM/PM Marker −Format f = new SimpleDateFormat("hh:mm:ss a"); String strResult = f.format(new Date()); System.out.println("Time = "+strResult);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 MoreFormat a message with date in Java
To format the message with 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. The pattern contains placeholder ...
Read MoreImplicit conversion from UInt64 to Decimal in C#
The ulong type represents a 64-bit unsigned integer i.e. UInt64.To implicitly convert a 64-bit unsigned integer to a Decimal, firstly set UInt64 value.ulong val = ulong.MaxValue;To convert ulong to decimal, assign the value.decimal dec; dec = val;Let us see the above example.Exampleusing System; public class Demo { public static void Main() { ulong val = ulong.MaxValue; decimal dec; Console.WriteLine("Implicit conversion from Ulong to Decimal"); dec = val; Console.WriteLine("Decimal : "+dec); } }OutputImplicit conversion from Ulong to Decimal Decimal : 18446744073709551615

To initializes a string in C# is an easy task. Let’s say you want to set a name “Amit”, for that, initialize your string as.String str1 = "Hello, World!";To compare strings, use the the following C# method.public static int Compare(string str1, string str2)To compare, if −String.Compare(str1, str2) == 0If the above is equal to 0, then both the strings are equal.The above method compares two specified string objects and returns an integer that indicates their relative position in the sort order.The following is an example that shows the comparison of one string to another.Exampleusing System; namespace Demo { class ...
