In what states can a stream be?

A thread in Java can be in the following main states, defined by the enumeration Thread.State:

• NEW: The thread has been created but not yet started.
• RUNNABLE: The thread is executing in the JVM but may be waiting for CPU time allocated by the operating system. Includes Running and Ready states.
• BLOCKED: The thread is blocked and waiting for a monitor lock to enter a synchronized block or method, or reenter it.
• WAITING: The thread is waiting for another thread to perform a specific action without a time limit. For example, by calling Object.wait(), Thread.join() without a timeout, or LockSupport.park().
• TIMED_WAITING: The thread is waiting for another thread to perform a specific action within a specified period. For example, by calling Thread.sleep(), Object.wait() with a timeout, Thread.join() with a timeout, LockSupport.parkNanos(), or LockSupport.parkUntil().
• TERMINATED: The thread has finished execution.

The thread states can be obtained using the method thread.getState().
