Assignment 1 ( 5 Marks)

Topic: Multithreading

Points:

·         What are threads?

·         Life cycle of thread

·         Creating threads - Thread class, Runnable interface

·         Thread priorities

·         Running multiple threads

·         Synchronization and interthread communication

Objective:

The objective of this assignment is to help students understand the concept of multithreading in Java programming. The assignment will require students to develop a multithreaded application and implement synchronization and interthread communication.

Assignment:

You are required to develop a multithreaded application that simulates a scenario where multiple threads are accessing a shared resource. The application should consist of the following components:

·         A shared resource: You can choose any resource, such as a database, file, or buffer.

·         Multiple threads: Create at least two threads that will access the shared resource simultaneously.

·         Thread creation: Use both Thread class and Runnable interface to create threads.

·         Life cycle of thread: Implement the different stages of thread life cycle, such as new, runnable, and terminated.

·         Thread priority: Implement thread priority to control the execution sequence of threads.

·         Execution of thread application: Implement the main method to execute the thread application.

·         Synchronization: Implement synchronization to ensure that only one thread can access the shared resource at a time.

·         Interthread communication: Implement interthread communication to allow threads to communicate with each other.

Questions for Students:

1.      Explain the concept of multithreading and its benefits. Why is multithreading essential in modern programming?

2.      What are threads? How are threads different from processes? Explain the advantages and disadvantages of using threads.

3.      Implement a Java program that uses Thread class and Runnable interface to create threads. Compare and contrast the advantages and disadvantages of using Thread class versus Runnable interface.

4.      Explain the different stages of the thread life cycle. How can you control the execution of threads using thread priority?

5.      How can you run multiple threads simultaneously in Java? Explain the challenges involved in running multiple threads.

6.      Implement synchronization in your multithreaded application. Explain how synchronization works and its role in multithreading.

7.      Implement interthread communication in your multithreaded application. Explain how interthread communication works and its role in multithreading.

8.      What are the potential issues that can arise when multiple threads access a shared resource simultaneously? How can you prevent these issues from occurring?

Note: The students are expected to provide detailed answers to each question and demonstrate their understanding of multithreading concepts. They should also use relevant code snippets and examples to support their answers.
