AtomicLong getAndAdd() method in Java with examples
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:
import java.util.concurrent.atomic.AtomicLong;
public class GFG {
public static void main(String args[])
{
AtomicLong val = new AtomicLong( 0 );
long res
= val.getAndAdd( 7 );
System.out.println( "Previous value: "
+ res);
System.out.println( "Current value: "
+ val);
}
}
|
Output:
Previous value: 0
Current value: 7
Program 2:
import java.util.concurrent.atomic.AtomicLong;
public class GFG {
public static void main(String args[])
{
AtomicLong val = new AtomicLong( 18 );
System.out.println( "Previous value: "
+ val);
long res = val.getAndAdd( 8 );
System.out.println( "Previous value: "
+ res);
System.out.println( "Current value: "
+ val);
}
}
|
Output:
Previous value: 18
Previous value: 18
