Truncate BigDecimal value in Java
The truncate BigDecimal value in Java, try the following code.Here, we have taken two BigDecimla values and set the round mode for truncating the decimal values −Exampleimport java.math.BigDecimal; public class Demo { public static void main(String[] argv) throws Exception { int decPlaces1 = 3; int decPlaces2 = 5; BigDecimal val1 = new BigDecimal("37578975587.876876989"); BigDecimal val2 = new BigDecimal("62567875598.976876569"); System.out.println("Value 1 : "+val1); ...
Read MoreConvert double primitive type to a Double object in Java
To convert double primitive type to a Double object, you need to use Double constructor.Let’s say the following is our double primitive.// double primitive double val = 23.78;To convert it to a Double object, use Double constructor.// Double object Double ob = new Double(val);Examplepublic class Demo { public static void main(String args[]) { // double primitive double val = 23.78; // Double object Double ob = new Double(val); System.out.println(ob); } }Output23.78
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 ...
Read MoreJava Program to convert an UNSIGNED byte to a JAVA type
Firstly, let us declare byte values.byte val1 = 127; byte val2 = -128;To convert the above given unsigned byte, you can use the following. Here, we are first implementing it for the variable “val1”.(int) val1 & 0xFFNow for the second variable “val2”.(int) val2 & 0xFFLet us see the complete example to convert an UNSIGNED bye to a JAVA type.Exampleimport java.util.*; public class Demo { public static void main(String[] args) { byte val1 = 127; byte val2 = -128; System.out.println(val1); System.out.println((int) val1 & 0xFF); System.out.println(val2); System.out.println((int) val2 & 0xFF); } }Output127 127 -128 128
Read MoreDecimalFormat(abc#) in Java
DecimalFormat is a concrete subclass of NumberFormat that formats decimal numbers.Let us set DecimalFormat(abc#) first −Format f = new DecimalFormat("'abc'#");Now, we will format a number and display the result in a string using the format() method −String res = f.format(-3968.7878);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 the complete example −Exampleimport java.text.DecimalFormat; import java.text.Format; public class Demo { public static void main(String[] argv) throws Exception { Format f = new DecimalFormat("'abc'#"); ...
Read MoreFormat double with new DecimalFormat("0.#####E0") in Java
Firstly, set the double values −double d1 = 1.39876; double d2 = 2.39876; double d3 = 0.66920;Now, format the double values with new DecimalFormat("0.#####E0") −System.out.println(new DecimalFormat("0.#####E0").format(d1)); System.out.println(new DecimalFormat("0.#####E0").format(d2)); System.out.println(new DecimalFormat("0.#####E0").format(d3));The following is an example −Exampleimport java.text.DecimalFormat; public class Demo { public static void main(String[] argv) throws Exception { double d1 = 1.39876; double d2 = 2.39876; double d3 = 0.66920; System.out.println(new DecimalFormat("0.#####E0").format(d1)); System.out.println(new DecimalFormat("0.#####E0").format(d2)); System.out.println(new DecimalFormat("0.#####E0").format(d3)); } }Output1.39876E0 2.39876E0 6.692E-1
Read MoreWhat is the IsReadOnly property of ArrayList class in C#?
The IsReadOnly property of ArrayList class is useful to get a value indicating whether the ArrayList is read-only.Firstly, we have the following ArrayList.ArrayList arrList = new ArrayList();Then we have checked using the IsReadOnly Property.Console.WriteLine("myArrayList.IsReadOnly = " + arrList.IsReadOnly);The following is an example showing how to work with IsReadOnly property in ArrayList class.Exampleusing System; using System.Collections; class Demo { public static void Main() { ArrayList arrList = new ArrayList(); Console.WriteLine("myArrayList.IsReadOnly = " + arrList.IsReadOnly); } }OutputmyArrayList.IsReadOnly = False
Read MoreFormat 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)); ...
Read MoreSimpleDateFormat(“hh:mm:ss a”) in Java
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 MoreHow to Initialize and Compare Strings in C#?
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 ...
