Type Parameters:: T - Value type in the case of success.

All Superinterfaces:: Iterable<T>, Serializable, Value<T>

All Known Implementing Classes:: Try.Failure, Try.Success

public interface Try<T> extends Value<T>, Serializable

The Try control gives us the ability write safe code without focusing on try-catch blocks in the presence of exceptions.

The following exceptions are considered to be fatal/non-recoverable:

InterruptedException
LinkageError
ThreadDeath
VirtualMachineError (i.e. OutOfMemoryError or StackOverflowError)

Important note: Try may re-throw (undeclared) exceptions, e.g. on get(). From within a dynamic proxy InvocationHandler this will lead to an UndeclaredThrowableException. For more information, please read Dynamic Proxy Classes.
