Example 1: Java Program to Convert long to int using Typecasting
class LongToInt { public static void main(String[] args) { // create long variables long a = 2322331L; long b = 52341241L; // convert long into int using typecasting int c = (int)a; int d = (int)b; System.out.println(c); System.out.println(d); } }
Output
2322331 52341241
Example 2: long to int conversion using toIntExact()
class LongToInt { public static void main(String[] args) { // create two long variables long value1 = 52133L; long value2 = -445436L; // change long to int using toIntExact() method int num1 = Math.toIntExact(value1); int num2 = Math.toIntExact(value2); // print the value System.out.println(num1); System.out.println(num2); } }
Output
52133 -445436
Example 3: Convert object of the Long class to int
class LongObjectToInt { public static void main(String[] args) { Long obj = 52323241L; // convert object of Long into int using intValue() int a = obj.intValue(); System.out.println(a); } }
Output
52323241
As you know, Object Class is the super class of all the classes, you can use intValue() method on object class to concert a Long Object into int.
