AtomicLong incrementAndGet() method in Java with examples
The Java.util.concurrent.atomic.AtomicLong.incrementAndGet() is an inbuilt method in java that increases the previous value by one and returns the value after updation which is of data-type long.
Syntax:
public final long incrementAndGet()
Parameters: The function does not accepts a single parameter.
Return value: The function returns the value after increment operation is performed to the previous value.
Below programs illustrate the above method:
Program 1:
Java
// Java program that demonstrates // the incrementAndGet() function import java.util.concurrent.atomic.AtomicLong; public class GFG { public static void main(String args[]) { // Initially value as 0 AtomicLong val = new AtomicLong( 0 ); System.out.println( "Previous value: " + val); // Increment and get long res = val.incrementAndGet(); // Prints the updated value System.out.println( "Current value: " + res); } } |
Output:
Previous value: 0 Current value: 1
Program 2:
Java
// Java program that demonstrates // the incrementAndGet() function import java.util.concurrent.atomic.AtomicLong; public class GFG { public static void main(String args[]) { // Initially value as 18 AtomicLong val = new AtomicLong( 18 ); System.out.println( "Previous value: " + val); // Increment and get new value long res = val.incrementAndGet(); // Prints the updated value System.out.println( "Current value: " + res); } } |
Output:
Previous value: 18 Current value: 19
