11.5.2   The Class

Error

The class

Error

 and its standard subclasses are exceptions from which ordinary

programs are not ordinarily expected to recover. The class

Error

 is a separate

subclass of

Throwable

, distinct from

Exception

 in the class hierarchy, to allow

programs to use the idiom:

} catch (Exception e) {

errors from which recovery is typically not possible.

Package

java.lang

 defines all the error classes described here. These

java.lang
