Set Decimal Place of a Big Decimal Value in Java
We have the following BigDecimal value −BigDecimal val1 = new BigDecimal("37578975587.876876989");We have set the decimal place to be −int decPlaces1 = 3;Now, we will use the ROUND_DOWN field to set the rounding mode to round towards zero −// ROUND_DOWN val1 = val1.setScale(decPlaces1, BigDecimal.ROUND_DOWN); String str1 = val1.toString(); System.out.println("Result = "+str1);To set decimal place of a BigDecimal value in Java, try the following code −Exampleimport java.math.BigDecimal; public class Demo { public static void main(String[] argv) throws Exception { int decPlaces1 = 3; int decPlaces2 = 5; ...

The following is an example displaying the minimum of three integer values.Examplepublic class Demo { public static void main(String[] args) { int val1 = 99; int val2 = 87; int val3 = 130; System.out.println("Number 1 = "+val1); System.out.println("Number 2 = "+val2); System.out.println("Number 3 = "+val3); if (val2 < val1) { val1 = val2; } if (val3 < val1) { val1 = val3; ...
Read MoreTruncate 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 MoreHow to format message with integer fillers in Java
To format message with integer 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 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 maximum of three long values
Firstly, let us declare and initialize three long values −long val1 = 98799; long val2 = 98567; long val3 = 98768;Now, find the maximum 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 maximum value −Examplepublic class Demo { public static void main(String[] args) { long val1 = 98799; long ...

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 MoreConvert a byte to hexadecimal equivalent in Java
To convert a byte to hexadecimal equivalent, use the toHexString() method in Java.Firstly, let us take a byte value.byte val1 = (byte)90;Before using the method, let us do some more manipulations. Mask the byte value now:int res = val1 & 0xFF;Let us now see the complete example and use the toHexString() method to convert a byte to hexadecimal equivalent.Examplepublic class Demo { public static void main(String[] args) { byte val1 = (byte)90; System.out.println("Byte = "+val1); int res = val1 & 0xFF; System.out.println("Hexadecimal = "+Integer.toHexString(res)); } }OutputByte = 90 Hexadecimal = 5a
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'#"); ...
