Type Parameters:

T - Value type in the case of success.

All Superinterfaces:

java.lang.Iterable<T>, java.io.Serializable, Value<T>

All Known Implementing Classes:

Try.Failure, Try.Success
```
public interface Try<T>
extends Value<T>, java.io.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.
