Java Program to check for Integer overflow
To check for Integer overflow, we need to check the Integer.MAX_VALUE, which is the maximum value of an integer in Java.Let us see an example wherein integers are added and if the sum is more than the Integer.MAX_VALUE, then an exception is thrown.Examplepublic class Demo { public static void main(String[] args) { int val1 = 9898989; int val2 = 6789054; System.out.println("Value1: "+val1); System.out.println("Value2: "+val2); long sum = (long)val1 + (long)val2; if (sum > Integer.MAX_VALUE) { throw new ...

magic methods that allow us to do some pretty neat tricks in object oriented programming. These methods are identified by a two underscores (__) used as prefix and suffix. As example, function as interceptors that are automatically called when certain conditions are met. In python __repr__ is a built-in function used to compute the "official" string representation of an object, while __str__ is a built-in function that computes the "informal" string representations of an object. Example Code class String: # magic method to initiate object def __init__(self, string): ...

Use the Convert.ToInt32() method to convert a specified value to a 32-bit signed integer.Let us take a double variable.double doubleNum = 11.53;Now, we will convert it to Int32 using the Convert.ToInt32 method.int intNum; ntNum = Convert.ToInt32(doubleNum);Exampleusing System; public class Demo { public static void Main() { double doubleNum = 11.53; int intNum; intNum = Convert.ToInt32(doubleNum); Console.WriteLine("Converted {0} to {1}", doubleNum, intNum); } }OutputConverted 11.53 to 12

A sorted list is a combination of an array and a hash table. It contains a list of items that can be accessed using a key or an index.Gets and sets the value associated with a specific key in the SortedList.You can also use the Item property to add new elements.If a key does not exist, then you can include it like.myCollection["myNonexistentKey"] = myValueIf the key already exist, then it will overwrite it with the new key and value.The following is an example to learn how to work with Item property of SorteList class in C#.Exampleusing System; using System.Collections; namespace ...

The following is an example displaying the maximum of three integer values.Examplepublic class Demo { public static void main(String[] args) { int val1 = 10; int val2 = 20; int val3 = 30; 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 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'#"); ...
