If in the main activity, android.os.Handler is passed from a constructor to a new thread. Can that new thread access view object? Can it post to the handler?
Homework Answers
If in the main activity, android.os.Handler is passed from a constructor to a new thread. Can that new thread access view object? Can it post to the handler?
- Yes, the new thread can access the view object as we can synchronize the main thread which will reduce the restriction and complexity of the threads and will provide us with the additional constructed classes for handling concurrently.
- The handler will allow communicating back with the user interface from the new thread in the background and then the handler will allow us to send and process the message and the runnable objects.
- Later on, the handler can be made use to schedule messages and the runnable for executing at the same point in the future or can be made use of the same thread in mere future.
- It can also be used to enqueue the action to be performed on the different or new thread which is been made concurrently.
Hence, this is how the android.os.Handler will be useful to view objects.

1. Analyze the following code: public class Test implements Runnable { public static void main(String[] args) { Thread t = new Thread(this); t.start(); } public void run() { System.out.println("test"); } } 1. The code compiles but will not print anything since t does not invoke the run method. 2. The code will not compile since you cannot invoke "this" in a static method. 3. The program compiles, runs, and prints tests on the console. 2. What will the following example...

Problem 3: (15 pts) Modify the Patient class with two overloaded constructors: A new default constructor which initializes the data items for a patient object using code within the constructor (use any data). A second constructor with parameters to pass all the data items into the object at the time of instantiation. Create a test main class which instantiates two objects. Instantiate the first object using the default constructor and the second object using the constructor with the parameters.
