After an object throws an exception, it is generally desirable that the object still be in a well-defined, usable state, even if the failure occurred in the midst of performing an operation. This is especially true for checked exceptions, from which the caller is expected to recover. Generally speaking, a failed method invocation should leave the object in the state that it was in prior to the invocation. A method with this property is said to be failure atomic.

There are several ways to achieve this effect. The simplest is to design immutable objects (Item 15). If an object is immutable, failure atomicity is free. If an operation fails, it may prevent a new object from getting created, but it will never leave an existing object in an inconsistent state, because the state of each object is consistent when it is created and can’t be modified thereafter.

For methods that operate on mutable objects, the most common way to achieve failure atomicity is to check parameters for validity before performing the opera

We generally hold to this, although sometimes a checked exception from client code means an unrecoverable exception to us, and is rethrown.

The Java programming language provides three kinds of throwables: checked exceptions, runtime exceptions, and errors. There is some confusion among programmers as to when it is appropriate to use each kind of throwable. While the decision is not always clear-cut, there are some general rules that provide strong guidance.

The cardinal rule in deciding whether to use a checked or an unchecked exception is this: use checked exceptions for conditions from which the caller can reasonably be expected to recover. By throwing a checked exception, you force the caller to handle the exception in a catch clause or to propagate it outward. Each checked exception that a method is declared to throw is therefore a potent indication to the API user that the associated condition is a possible outcome of invoking the method.

By confronting the API user with a checked exception, the API
