- Method Detail
  - getActiveCount
```
@MXBeanDescription(value="Approximate number of threads that are actively executing tasks.")
int getActiveCount()
```
    Deprecated.
    
    Returns the approximate number of threads that are actively executing tasks.
    
    Returns:
    
    The number of threads.
  - getCompletedTaskCount
```
@MXBeanDescription(value="Approximate total number of tasks that have completed execution.")
long getCompletedTaskCount()
```
    Deprecated.
    
    Returns the approximate total number of tasks that have completed execution. Because the states of tasks and threads may change dynamically during computation, the returned value is only an approximation, but one that does not ever decrease across successive calls.
    
    Returns:
    
    The number of tasks.
  - getCorePoolSize
```
@MXBeanDescription(value="The core number of threads.")
int getCorePoolSize()
```
    Deprecated.
    
    Returns the core number of threads.
    
    Returns:
    
    The core number of threads.
  - getLargestPoolSize
```
@MXBeanDescription(value="Largest number of threads that have ever simultaneously been in the pool.")
int getLargestPoolSize()
```
    Deprecated.
    
    Returns the largest number of threads that have ever simultaneously been in the pool.
    
    Returns:
    
    The number of threads.
  - getMaximumPoolSize
```
@MXBeanDescription(value="The maximum allowed number of threads.")
int getMaximumPoolSize()
```
    Deprecated.
    
    Returns the maximum allowed number of threads.
    
    Returns:
    
    The maximum allowed number of threads.
  - getPoolSize
```
@MXBeanDescription(value="Current number of threads in the pool.")
int getPoolSize()
```
    Deprecated.
    
    Returns the current number of threads in the pool.
    
    Returns:
    
    The number of threads.
  - getTaskCount
```
@MXBeanDescription(value="Approximate total number of tasks that have been scheduled for execution.")
long getTaskCount()
```
    Deprecated.
    
    Returns the approximate total number of tasks that have been scheduled for execution. Because the states of tasks and threads may change dynamically during computation, the returned value is only an approximation, but one that does not ever decrease across successive calls.
    
    Returns:
    
    The number of tasks.
  - getQueueSize
```
@MXBeanDescription(value="Current size of the execution queue.")
int getQueueSize()
```
    Deprecated.
    
    Gets current size of the execution queue. This queue buffers local executions when there are not threads available for processing in the pool.
    
    Returns:
    
    Current size of the execution queue.
  - getKeepAliveTime
```
@MXBeanDescription(value="Thread keep-alive time, which is the amount of time which threads in excess of the core pool size may remain idle before being terminated.")
long getKeepAliveTime()
```
    Deprecated.
    
    Returns the thread keep-alive time, which is the amount of time which threads in excess of the core pool size may remain idle before being terminated.
    
    Returns:
    
    Keep alive time.
  - isShutdown
```
@MXBeanDescription(value="True if this executor has been shut down.")
boolean isShutdown()
```
    Deprecated.
    
    Returns true if this executor has been shut down.
    
    Returns:
    
    True if this executor has been shut down.
  - isTerminated
```
@MXBeanDescription(value="True if all tasks have completed following shut down.")
boolean isTerminated()
```
    Deprecated.
    
    Returns true if all tasks have completed following shut down. Note that isTerminated() is never true unless either shutdown() or shutdownNow() was called first.
    
    Returns:
    
    True if all tasks have completed following shut down.
  - isTerminating
```
@MXBeanDescription(value="True if terminating but not yet terminated.")
boolean isTerminating()
```
    Deprecated.
    
    Returns true if this executor is in the process of terminating after shutdown() or shutdownNow() but has not completely terminated. This method may be useful for debugging. A return of true reported a sufficient period after shutdown may indicate that submitted tasks have ignored or suppressed interruption, causing this executor not to properly terminate.
    
    Returns:
    
    True if terminating but not yet terminated.
  - getRejectedExecutionHandlerClass
```
@MXBeanDescription(value="Returns the class name of the handler for tasks that cannot be executed by the thread pool.")
String getRejectedExecutionHandlerClass()
```
    Deprecated.
    
    The class name of the handler for tasks that cannot be executed. This may occur when no more threads or queue slots are available because their bounds would be exceeded, or upon shutdown of the Executor.
    
    Returns:
    
    Class name of the handler for tasks that cannot be executed by the thread pool.
  - getThreadFactoryClass
```
@MXBeanDescription(value="Class name of thread factory used to create new threads.")
String getThreadFactoryClass()
```
    Deprecated.
    
    Returns the class name of thread factory used to create new threads.
    
    Returns:
    
    Class name of thread factory used to create new threads.
