AtomicLong represents a long value that may be updated atomically.

An atomic operation performs a single unit of work on a resource. During that operation, no other operations are allowed on the same resource until the performing operation is finished.

The AtomicLong class is present in the java.util.concurrent.atomic package.

This article is helpful if you want a greater understanding of the Atomic concept.

The intValue method of the AtomicLong will return the AtomicLong value as an integer value after a narrowing primitive conversion.

Syntax

public int intValue()

Arguments

This method doesn’t take any argument.

Return value

This method returns the AtomicLong object’s numeric value as an int value.

Working example

The code below demonstrates how to use the intValue method:

import java.util.concurrent.atomic.AtomicLong;
class IntValue{
public static void main(String[] args) {
AtomicLong atomicLong = new AtomicLong(10);
long val = atomicLong.get();
System.out.println("The value in the atomicLong object is " + val);
int intVal = atomicLong.intValue();
System.out.println("\natomicLong.intValue() : " + intVal);
}
}
Using the intValue method

Explanation

  • Line 1: We have imported the AtomicLong class.
  • Line 4: Created a new object for the AtomicLong class with the name atomicLong and with the value 10.
  • Line 8: Used the intValue method to get the value of the atomicLong object as an integer value.
