- Java.util.concurrent.atomic package provides very useful classes that support lock free and thread safe programming.
- The main use of this class is an int value that may be updated automatically.
- AtomicInteger has some useful methods. Before that lets see the some points about this class.
- Commonly we will use this AtomicInteger to handle the counter that is accessible by different threads simultaneously.
Java.util.concurrent.atomic.AtomicInteger:- public class AtomicInteger
- extends Number
- implements Serializable
AtomicInteger Class Constructors:- public AtomicInteger(): Creates a new AtomicInteger object with default value 0.
- AtomicInteger atomicInteger = new AtomicInteger();
- public AtomicInteger(int initialValue): Creates a new AtomicInteger object with given initial value.
- AtomicInteger atomicInteger = new AtomicInteger(10);
AtomicInteger Class Methods: 1.public final void set(int newValue):- Sets given value to the object.
1. Java Program to create AtomicInteger class object and sets some value.- package com.instaceofjava;
-
- import java.util.concurrent.atomic.AtomicInteger;
-
- public class AtomicIntegerExample{
-
- public static void main(String[] args) {
-
- AtomicInteger atomicInteger = new AtomicInteger();
-
- System.out.println(atomicInteger);
- atomicInteger.set(10);
- System.out.println(atomicInteger);
-
- }
-
- }
Output: 2.public final void get():- Used to get current value.
