How to convert Java long to int

In Java, a long can be converted into an int using the typecast operator. This is because, in order to convert a higher data type into a lower data type, typecasting needs to be performed and this type of conversion is called Typecasting conversion.

In Java, Typecasting is performed through the typecast operator (datatype).

Example 1:

Here, the primitive long value is converted into int using the typecasting operator.

 public class StudyTonight { public static void main(String args[]) { long l = 500L; int i = (int)l; //typecasting System.out.println("The int value is " +i); } }

The int value is 500

Also, we can convert a Long object to an int by intValue() method of Long class.

Example 2:

Here, the Long object is converted into int by using the intValue() method.

 public class StudyTonight { public static void main(String args[]) { Long l = new Long(50); int i = l.intValue(); System.out.println("The int value is : " +i); } }

The int value is : 50

Example 3:

Here, the primitive long value is converted into int using toIntExact() method of the Math class.

 public class StudyTonight { public static void main(String args[]) { long l = 100L; int i = Math.toIntExact(l); System.out.println("The int value is " +i); } }

The int value is 100
