ExecutionException

AI-generated Key Takeaways

• ExecutionException signals that a task aborted due to an exception, allowing inspection of the cause via Throwable.getCause().

• It's commonly used with Future for retrieving results from asynchronous tasks.

• Provides constructors to initialize with a detail message, a cause, or both.

• Inherits methods from Throwable for stack trace and exception handling.

public class ExecutionException extends Exception

Exception thrown when attempting to retrieve the result of a task that aborted by throwing an exception. This exception can be inspected using the Throwable.getCause() method.

final void	wait() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.

Public Constructors

public ExecutionException (String message, Throwable cause)

Constructs an ExecutionException with the specified detail message and cause.

Parameters

message	the detail message
cause	the cause (which is saved for later retrieval by the Throwable.getCause() method)

public ExecutionException (Throwable cause)

Constructs an ExecutionException with the specified cause. The detail message is set to (cause == null ? null : cause.toString()) (which typically contains the class and detail message of cause).

Parameters

cause	the cause (which is saved for later retrieval by the Throwable.getCause() method)

Protected Constructors

protected ExecutionException ()

Constructs an ExecutionException with no detail message. The cause is not initialized, and may subsequently be initialized by a call to initCause.

protected ExecutionException (String message)

Constructs an ExecutionException with the specified detail message. The cause is not initialized, and may subsequently be initialized by a call to initCause.

Parameters

message	the detail message
