Java Multithreading and Parallel Programming Masterclass - Thread Priorities and States

The video tutorial covers thread priorities and states in Java. It explains how thread priorities can influence the thread scheduler's decision to allocate CPU time, though it is not guaranteed. The tutorial also discusses the default priority values and how they can be inherited or changed. A practical example demonstrates how threads with different priorities are scheduled. The second part of the tutorial introduces thread states, explaining the lifecycle of a thread from creation to termination. It highlights the importance of understanding thread states for debugging purposes.

What is the default priority value for a new thread in Java?

• 0

• 10

• 5

• 1

How does the thread scheduler decide which thread to run?

• Based on thread priority

• Based on thread name

• Randomly

• In the order of creation

Why should you not rely on thread priority for program correctness?

• Because it is not supported in Java

• Because it is only a hint to the scheduler

• Because it causes errors

• Because it is deprecated

Which state does a thread enter after it is created but not yet started?

• Runnable

• Blocked

• New

• Terminated

What is the state of a thread that is ready to run but not currently executing?

• Runnable

• Terminated

• Blocked

• New

What is a thread dump used for?

• To increase thread priority

• To debug threads by capturing their states and stack traces

• To terminate threads

• To create new threads

What happens to a thread's state when it is joined with the main thread?

• It becomes Terminated

• It becomes New

• It becomes Blocked

• It becomes Runnable
