AtomicInteger set() method in Java with examples
The java.util.concurrent.atomic.AtomicInteger.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(int newVal)
Parameters: The function accepts a single mandatory parameter newVal which is to be updated.
Return value: The function does not returns anything.
Program below demonstrates the function:
Program 1:
// Java program that demonstrates // the set() function import java.util.concurrent.atomic.AtomicInteger; public class GFG { public static void main(String args[]) { // Initially value as 0 AtomicInteger val = new AtomicInteger(0); System.out.println("Previous value: " + val); val.set(10); // Prints the updated value System.out.println("Current value: " + val); } } |

Program 2:
// Java program that demonstrates // the set() function import java.util.concurrent.atomic.AtomicInteger; public class GFG { public static void main(String args[]) { // Initially value as 18 AtomicInteger val = new AtomicInteger(18); System.out.println("Previous value: " + val); val.set(200); // Prints the updated value System.out.println("Current value: " + val); } } |
