Java Programming for Complete Beginners - Java 16 - Step 08 - Need for Controlling the Execution of Threads

The video tutorial discusses the limitations of basic thread management, such as lack of control over execution and difficulty in managing multiple threads. It highlights the challenges of waiting for task completion and returning results. The tutorial introduces the executor service as a solution, offering better control, monitoring, and management of threads, allowing for more efficient execution and result handling.

What is a major limitation of basic thread management?

• It allows too many threads to run simultaneously.

• It provides too much control over thread execution.

• It automatically manages thread priorities.

• It can only run one thread at a time.

Why is managing multiple threads considered tedious?

• Because threads can only be run sequentially.

• Because threads automatically synchronize with each other.

• Because it requires writing complex code for each task.

• Because it is impossible to start threads manually.

What is a key feature of the executor service?

• It allows threads to run without any control.

• It provides facilities to manage and monitor threads.

• It automatically completes all tasks without user input.

• It limits the number of threads to one.

How does the executor service improve task completion handling?

• By enabling logic to handle task completion efficiently.

• By preventing any task from completing before others.

• By ensuring all tasks start at the same time.

• By allowing tasks to run indefinitely.

What problem does the executor service solve regarding thread results?

• It ensures all threads return the same result.

• It allows threads to return results after completion.

• It discards all results from threads.

• It prevents threads from returning any results.
