The Java.util.concurrent.atomic.AtomicLong.set() is an inbuilt method in java that updates the previous value and sets it to a new value which is passed in the parameter.
Syntax:
public final void set(long newVal)
Parameters: The function accepts a single mandatory parameter newVal which is to be updated.
Return value: The function does not returns anything.
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 );
System.out.println( "Previous value: "
+ val);
val.set( 10 );
System.out.println( "Current value: "
+ val);
}
}
|
Output:
Previous value: 0
Current value: 10
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);
val.set( 200 );
System.out.println( "Current value: "
+ val);
}
}

Output:
Previous value: 18
