```
public class Thread
extends Object
implements Runnable
```
A Thread is a concurrent unit of execution. It has its own call stack for methods being invoked, their arguments and local variables. Each application has at least one thread running when it is started, the main thread, in the main ThreadGroup. The runtime keeps its own threads in the system thread group.
There are two ways to execute code in a new thread. You can either subclass Thread and overriding its run() method, or construct a new Thread and pass a Runnable to the constructor. In either case, the start() method must be called to actually execute the new Thread.
Each Thread has an integer priority that affect how the thread is scheduled by the OS. A new thread inherits the priority of its parent. A thread's priority can be set using the setPriority(int) method.

    - Threads blocked in an I/O operation of an InterruptibleChannel will have their interrupt status set and receive an ClosedByInterruptException. Also, the channel will be closed.
    - Threads blocked in a Selector will have their interrupt status set and return immediately. They don't receive an exception in this case.
    See Also:
    
    interrupted(), isInterrupted()
  - interrupted
```
public static boolean interrupted()
```
    Returns a boolean indicating whether the current Thread ( currentThread()) has a pending interrupt request (true) or not (false). It also has the side-effect of clearing the flag.

  - setUncaughtExceptionHandler
```

    Parameters:
    
    time - The time to sleep in milliseconds.
    
    Throws:

    See Also:
    
    interrupt()
  - start
```
public void start()
```
    Starts the new Thread of execution. The run() method of the receiver will be called by the receiver Thread itself (and not the Thread calling start()).
    
    Throws:
    
    IllegalThreadStateException - - if this thread has already started.
    
    See Also:
    
    run()
  - stop
```
@Deprecated
public final void stop()
```
    Deprecated. because stopping a thread in this manner is unsafe and can leave your application and the VM in an unpredictable state.
    
    Requests the receiver Thread to stop and throw ThreadDeath. The Thread is resumed if it was suspended and awakened if it was sleeping, so that it can proceed to throw ThreadDeath.
  - stop
```
@Deprecated
public final void stop(Throwable throwable)
```
    Deprecated. because stopping a thread in this manner is unsafe and can leave your application and the VM in an unpredictable state.
    
    Throws UnsupportedOperationException.
  - suspend
```
@Deprecated
public final void suspend()
```
    Deprecated. May cause deadlocks.
    
    Throws UnsupportedOperationException.

```
    Indicates whether the current Thread has a monitor lock on the specified object.
    
    Parameters:
    
    object - the object to test for the monitor lock
    
    Returns:
    
    true if the current thread has a monitor lock on the specified object; false otherwise
  - unpark$
```
public final void unpark$()
```
    Unparks this thread. This unblocks the thread it if it was previously parked, or indicates that the thread is "preemptively unparked" if it wasn't already parked. The latter means that the next time the thread is told to park, it will merely clear its latent park bit and carry on without blocking.
    See LockSupport for more in-depth information of the behavior of this method.
  - parkFor$
```
public final void parkFor$(long nanos)
```
    Parks the current thread for a particular number of nanoseconds, or indefinitely. If not indefinitely, this method unparks the thread after the given number of nanoseconds if no other thread unparks it first. If the thread has been "preemptively unparked," this method cancels that unparking and returns immediately. This method may also return spuriously (that is, without the thread being told to unpark and without the indicated amount of time elapsing).
    See LockSupport for more in-depth information of the behavior of this method.
    
    This method must only be called when this is the current thread.
    
    Parameters:
    
    nanos - number of nanoseconds to park for or 0 to park indefinitely
    
    Throws:
    
    IllegalArgumentException - thrown if nanos < 0
  - parkUntil$
```
public final void parkUntil$(long time)
```
    Parks the current thread until the specified system time. This method attempts to unpark the current thread immediately after System.currentTimeMillis() reaches the specified value, if no other thread unparks it first. If the thread has been "preemptively unparked," this method cancels that unparking and returns immediately. This method may also return spuriously (that is, without the thread being told to unpark and without the indicated amount of time elapsing).
    See LockSupport for more in-depth information of the behavior of this method.
    
    This method must only be called when this is the current thread.
    
    Parameters:
    
    time - the time after which the thread should be unparked, in absolute milliseconds-since-the-epoch
