# Class: com.pnfsoftware.jeb.util.concurrent.ThreadEx An extension of [Thread](Thread) supporting the execution of [Callable](Callable) as well as [Runnable](Runnable). Two additional `get()` and `get(timeout)` methods, not unlike [Future](Future)'s get\(\), allow querying and waiting for the execution result. When executing a Runnable, get\(\) will always return null. An exception occurring during the execution of the thread is collected and re\-thrown inside an [ExecutionException](ExecutionException) object. ## Constructor: ThreadEx - parameter: `runnable`, type: `java.lang.Runnable` Description: Create a thread that executes a runnable. parameter: runnable: non\-null runnable to execute ## Constructor: ThreadEx - parameter: `callable`, type: `java.util.concurrent.Callable` Description: Create a thread that executes a callable. parameter: callable: non\-null callable to execute ## Method: get - return type: `V` Description: Waits if necessary for the computation to complete, and then retrieves its result. return: the computed result; always null for a [Runnable](Runnable) throws: if the computation threw an exception throws: if the current thread was interrupted while waiting ## Method: get - parameter: `millis`, type: `long` - return type: `V` Description: Waits if necessary for at most the given time for the computation to complete, and then retrieves its result, if available. parameter: millis: the maximum time to wait, in milliseconds; 0 means wait forever return: the computed result; always null for a [Runnable](Runnable) throws: if the computation threw an exception throws: if the current thread was interrupted while waiting throws: if the wait timed out ## Method: run Description: Execute the configured runnable or callable.
