When a thread is created and started, what is its initial state

by

A thread is in the ready state after it has been created and started.

In Java, when a thread is created and started, its initial state is “NEW.” The thread is considered to be in the “NEW” state from the time it is created using the new keyword or by instantiating a class that extends the Thread class, until the start() method is called on it. Once the start() method is invoked, the thread transitions to the “RUNNABLE” state, and the Java Virtual Machine (JVM) is responsible for scheduling its execution.

Here is a brief overview of the possible states of a Java thread:

  1. NEW: The thread is in this state from the time it is created until the start() method is called.
  2. RUNNABLE: After calling the start() method, the thread is in the “RUNNABLE” state. It means that the thread is ready to run and is waiting for its turn to be scheduled by the JVM.
  3. BLOCKED: A thread is in the “BLOCKED” state when it is waiting for a monitor lock to enter a synchronized block or method.
  4. WAITING: A thread is in the “WAITING” state when it is waiting indefinitely for another thread to perform a particular action.
  5. TIMED_WAITING: Similar to the “WAITING” state, but the thread is waiting for a specified amount of time.
  6. TERMINATED: The thread is in the “TERMINATED” state when it has completed its execution or terminated abnormally.

The transition between these states is managed by the JVM and is influenced by various factors, such as synchronization, thread priority, and the scheduler.
