Can you explain what is meant by thread states in programming?

Thread state in programming is the current execution state of a thread, which determines what the thread is doing at the moment and what actions it can perform next.

The main thread states in Java (and in most languages with threading) include:

• New (Created but not started): the thread is created, but the start() method has not yet been called.
• Runnable (Ready to run): the thread is ready to execute and is waiting for the OS scheduler to allocate CPU time.
• Running: the thread is executing (usually this is an implicit state when the thread is in Runnable and gets the CPU).
• Blocked/Waiting: the thread is paused, waiting for a resource to be released or a notification.
• Timed Waiting: the thread is waiting with a time limit (e.g., sleep or wait with timeout).
• Terminated: the thread has finished execution.

Understanding these states is important for managing multithreading, debugging, and preventing issues such as deadlocks.
