Java AtomicLong addAndGet() Method

The addAndGet() method of Java AtomicLong class adds a number to the AtomicLong and returns its value after the addition.

Syntax

Parameters

delta - The value to add.

Return value
The updated value.
Example 1
import java.util.concurrent.atomic.AtomicLong; public class AtomicLongAddandGetExample1 { public static void main (String [] args) { AtomicLong atomiclong = new AtomicLong(); //adds this number to the Initialized value Long result = atomiclong.addAndGet(10); //Prints the added value after addition to the Initialized value System.out.println(result); } }
Test it Now
Output:
10
Example 2
import java.util.concurrent.atomic.AtomicLong; public class AtomicLongAddandGetExample2 { public static void main (String [] args) { AtomicLong atomiclong = new AtomicLong(10); //adds this number to the Initialized value Long result = atomiclong.addAndGet(10); //Prints the added value after addition to the Initialized value System.out.println(result); } }
Test it Now
Output:
20
Example 3
import java.util.concurrent.atomic.AtomicLong; public class AtomicLongAddandGetExample3 { public static void main (String [] args) { AtomicLong atomiclong = new AtomicLong(-5); //adds this number to the Initialized value Long result = atomiclong.addAndGet(10); //Prints the added value after addition to the Initialized value System.out.println(result); } }
Test it Now
Output:
5
Example 4
import java.util.concurrent.atomic.AtomicLong; public class AtomicLongAddandGetExample4 { public static void main (String [] args) { AtomicLong atomiclong = new AtomicLong(-20); //adds this number to the Initialized value Long result = atomiclong.addAndGet(-20); //Prints the added value after addition to the Initialized value System.out.println(result); } }
Test it Now
Output:
-40
