Java AtomicLong lazySet() Method

The lazySet() method of Java AtomicLong class sets the value to newValue. It has the memory effects of writing (assigning) a volatile variable except that it permits reorderings with subsequent (but not previous) memory actions that do not themselves impose reordering constraints with ordinary non-volatile writes. Among other usage contexts, lazySet may apply when nulling out, for the sake of garbage collection, a reference that is never accessed again.

Syntax

Parameters

newValue - the new value

Example 1

import java.util.concurrent.atomic.AtomicLong;
public class AtomicLongLazySetExample1 {
public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong();
		//Sets the Specified value
		atomiclong.lazySet(5);
		//Prints the Set value
		System.out.println(atomiclong);
	}
}

Output:

Example 2

import java.util.concurrent.atomic.AtomicLong;
public class AtomicLongLazySetExample2 {
	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong(10);
		//Sets the Specified value
		atomiclong.lazySet(9);
		//Prints the Set value
		System.out.println(atomiclong);
	}

	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong(20);
		//Sets the Specified value
		atomiclong.lazySet(-20L);
		//Prints the Set value
		System.out.println(atomiclong);
