Different ways to create a task and setting their task states

SettingTaskStates.cs

Task t1 = new Task(new Action<object>(printMessage), "Task 1"); //Use Action Delegate with Named Method + Setting State
t1.Start();

Task t2 = new Task(delegate (Object obj) { Console.WriteLine("Hello Alien! I am from {0}", obj); }, "Task 2"); //Use an anonymous delegate + Setting State
t2.Start();

Task t3 = new Task((obj) => printMessage(obj), "Task 3"); //Use Lambda Expression and named method + Setting State
t3.Start();

Task t4 = new Task((obj) => { Console.WriteLine("Hello Alien! I am from {0}", obj); }, "Task 4"); //Use Lambda Expression and an anonymous method + Setting Task State
t4.Start();
