AtomicLong getAndIncrement() method in Java with examples

The Java.util.concurrent.atomic.AtomicLong.getAndIncrement() is an inbuilt method in java that increases the given value by one and returns the value before updation which is of data-type long.

Syntax:

public final long getAndIncrement()

Parameters: The function does not accepts a single parameter.

Return value: The function returns the value before increment operation is performed to the previous value.

Below programs illustrate the above method:

Program 1:




// Java program that demonstrates
// the getAndIncrement() 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);
  
        // Decreases and gets
        // the previous value
        long res
            = val.getAndIncrement();
  
        System.out.println("Previous value: "
                           + res);
  
        // Prints the updated value
        System.out.println("Current value: "
                           + val);
    }
}


Output:

Previous value: 0
Current value: 1

Program 2:




// Java program that demonstrates
// the getAndIncrement() 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);
  
        // Increases 1 and gets
        // the previous value
        long res = val.getAndIncrement();
  
        System.out.println("Previous value: "
                           + res);
  
        // Prints the updated value
        System.out.println("Current value: "
                           + val);
    }
}


Output:

Previous value: 18
Current value: 19
