14.3. Creating Threads in Java

Try these first

1. 1.

   What is the method called that must be overridden when creating a thread by extending the Thread class?

   Hint

   Think about where the thread's action is defined.

2. 2.

   Which interface must a class implement to create a thread using the Runnable approach?

   Hint

   Focus on the method that needs to be defined.

3. 3.

   What method is called to start a thread in Java?

   • run()
   • execute()
   • start()

   Hint

   Recall the terminology associated with thread execution.

4. 4.

   True or False: You can directly invoke the run() method to start a thread.

   • True
   • False

   Hint

   Think about the implications of direct method calls vs. thread initiation.

5. 5.

   Create a class that implements the Runnable interface, then write a program that creates three threads to print numbers from 1 to 5.

   Hint

   Consider how many threads you are spawning and how they share the same implementation.

6. 6.

   Discuss the trade-offs of using the Thread class versus the Runnable interface when designing a multi-threaded application.

   Hint

   Reflect on how each design pattern can impact the scalability and maintainability of your code.
