Given a Double real number, the task is to convert it into Integer in Java.

Examples:

Input: double = 3452.234
Output: 3452

Input: double = 98.23
Output: 98

1. Using typecasting: This technique is a very simple and user friendly.

   Syntax:

   double data = 3452.345
   int value = (int)data;
   

   Example:

   
   

   
   
   

   // Java program to convert Double to int // using Typecasting    public class GFG {        // main method     public static void main(String args[])     {            // Get the double value         double data = 3452.345;            // convert into int         int value = (int)data;            // print the int value         System.out.println(value);     } }

   Output:

   
   

   
   

   3452
   

2. Using Math.round(): This method returns the nearest integer.

   Syntax:

   double data = 3452.645
   int value = (int)Math.round(data);
   

   Example:

   
   

   
   
   

   // Java program to convert Double to int // using Math.round()    public class GFG {        // main method     public static void main(String args[])     {            // Get the double value         double data = 3452.345;            // convert into int         int value = (int)Math.round(data);            // print the int value         System.out.println(value);     } }

   Output:

   3452
   

3. Using Double.intValue(): This technique is similar to typecasting method. Wrapper class Double truncates all digits after decimal point.

   Syntax:

   double data = 3452.345
   Double newData = new Double(data);
   int value = newData.intValue();
   

   Example:

   
   

   
   
   

   // Java program to convert Double to int // using using Double.intValue()    public class GFG {        // main method     public static void main(String args[])     {            // Get the double value         double data = 3452.345;            // Create a wrapper around         // the double value         Double newData = new Double(data);            // convert into int         int value = newData.intValue();            // print the int value         System.out.println(value);     } }

   Output:

   3452
