AtomicLong set() method in Java with examples

Last Updated : 29 Jan, 2019

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:

Java

// Java program that demonstrates
// the set() 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);

        System.out.println("Previous value: "
                           + val);

        val.set(10);

        // Prints the updated value
        System.out.println("Current value: "
                           + val);
    }
}

Output:

Previous value: 0
Current value: 10

Program 2:

Java

// Java program that demonstrates
// the set() 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);

        System.out.println("Previous value: "
                           + val);

        val.set(200);

        // Prints the updated value
        System.out.println("Current value: "
                           + val);
    }
}

Output:

Previous value: 18
Current value: 200
