Lesson 2: Synchronization
Lesson 2 Module 7: Multithreading-Synchronization focuses on ensuring thread safety in Java through synchronization. When multiple threads access shared resources, there is a need to synchronize their access to prevent data corruption or inconsistent results. This lesson covers synchronized methods and blocks, essential mechanisms for controlling access to critical sections in a multithreaded environment.
Lesson 1: Introduction to Multithreading
Lesson 1 Module 7: Multithreading-Introduction to Multithreading introduces the basics of multithreading in Java, a powerful mechanism that enables the concurrent execution of multiple threads. Multithreading is crucial for improving the performance and responsiveness of Java applications, allowing them to perform multiple tasks simultaneously.
Lesson 2: Serialization
Lesson 2 Serialization delves into the concept of object serialization in Java, a process that allows objects to be converted into a byte stream for storage or transmission. Serialization is crucial for saving and restoring the state of objects, especially when dealing with persistence or communication between different Java applications.
Lesson 1: Reading and Writing Files
Lesson 1 Reading and Writing Files introduces the essential concepts of reading from and writing to files in Java. This includes working with streams, which are sequences of data elements made available over time. Understanding file I/O operations is crucial for handling external data and interacting with files in Java applications.
Lesson 2: Try-Catch Blocks
Lesson 2 Try-Catch Blocks dives deeper into the practical aspects of exception handling by exploring the use of try-catch blocks. These blocks are fundamental for handling exceptions in Java, allowing developers to gracefully manage errors and unexpected situations in their code
Lesson 1: Understanding Exceptions
Lesson 1 Understanding Exceptions focuses on understanding exceptions in Java, which are events that disrupt the normal flow of a program. Handling exceptions is essential for writing robust and error-tolerant applications.
Lesson 3: Collections Framework
Introduction to collections (List, Set, Map)
Iterating and manipulating collections
Lesson 3 introduces the Collections Framework in Java, providing a powerful set of classes and interfaces for working with collections of objects. Collections allow developers to manage and manipulate groups of items efficiently.
