Thread safety in java is the process to make our program safe to use in multithreaded environment, there are different ways through which we can make our program thread safe. Synchronization is the easiest and most widely used tool for thread safety in java. Use of Atomic Wrapper classes from...
(since the assignment is atomic) and will be a lot faster than the one where the synchronization is happening at every call. I would agree that this would a bit too extreme for someone who is starting to learn java. But for someone a bit experienced who will understand what is happening...
In software engineering, thesingleton patternis a design pattern that restricts theinstantiationof a class toone object. This is useful when exactlyone objectis needed to coordinate actions across the system. The concept is sometimes generalized to systems that operate moreefficientlywhen only one obje...
Use thesynchronizedMethod for Thread-Safe Lazy Initialization in Java In this example, we have two customer threads. The_instancevariable checks whether an instance is null. If the variable is null, the program creates an instance. The empty flag checks whether the token is available or not. ...
Thread Safe Singleton in Java In general, we follow the below steps to create a singleton class: Create the privateconstructor static ASingleton.java package com.journaldev.designpatterns; public class ASingleton { private static ASingleton instance = null; ...
Make a method thread-safe – Method 2 In this particular counter example, we actually can makecount++atomic by using AtomicInteger from the package “java.util.concurrent.atomic”. importjava.util.concurrent.atomic.AtomicInteger;publicclassMyCounter{privatestaticAtomicInteger counter=newAtomicInteger(0);...
Java Code: importjava.util.concurrent.locks.Lock;importjava.util.concurrent.locks.ReentrantLock;publicclassBankAccount{privatedoublebalance;privateLocklock;publicBankAccount(){balance=0.0;lock=newReentrantLock();}publicvoiddeposit(doubleamount){lock.lock();try{balance+=amount;System.out.println("Deposit: ...
Some Swing component methods are labelled "thread safe" in the API specification; these can be safely invoked from any thread. All other Swing component methods must be invoked from the event dispatch thread. Programs that ignore this rule may function correctly most of the time, but are ...

The other way can be to use a concurrent set from the java concurrent package. The set that is returned from the map is backed by the map itself -- meaning wrapping it in a synchronizedSet() is definitely not enough. I would recommend using synchronizedMap on the private map variable ...
