The Java.util.concurrent.atomic.AtomicLong.getAndAdd() is an inbuilt method in java that adds the given value to the current value and returns the value before updation which is of data-type long.
Syntax:
public final long getAndAdd(long val)
Parameters: The function accepts a single mandatory parameter val which specifies the value to be added to the current value.
Return value: The function returns the value before addition is performed to the previous value.
Below programs illustrate the above method:
Program 1:
// Java program that demonstrates// the getAndAdd() 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);          // Adds 7 and gets the previous value        long res            = val.getAndAdd(7);          // Prints the updated value        System.out.println("Previous value: "                           + res);          System.out.println("Current value: "                           + val);    }} |
Output:
Previous value: 0 Current value: 7
Program 2:
// Java program that demonstrates// the getAndAdd() 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);          // Prints the updated value        System.out.println("Previous value: "                           + val);          // Adds 8 and gets the previous value        long res = val.getAndAdd(8);          // Prints the updated value        System.out.println("Previous value: "                           + res);          System.out.println("Current value: "                           + val);    }} |
Output:
Previous value: 18 Previous value: 18 Current value: 26
