&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&package&java.&import&; The Throwable class is the superclass of all errors and
exceptions in the Java language. Only objects that are instances of this
class (or one of its subclasses) are thrown by the Java Virtual Machine or
can be thrown by the Java throw statement. Similarly, only
this class or one of its subclasses can be the argument type in a
catch clause.
Instances of two subclasses,
, are conventionally used to indicate
that exceptional situations have occurred. Typically, these instances
are freshly created in the context of the exceptional situation so
as to include relevant information (such as stack trace data).
A throwable contains a snapshot of the execution stack of its thread at
the time it was created. It can also contain a message string that gives
more information about the error. Finally, it can contain a cause:
another throwable that caused this throwable to get thrown.
facility is new in release 1.4.
It is also known as the chained
exception facility, as the cause can, itself, have a cause, and so on,
leading to a &chain& of exceptions, each caused by another.
One reason that a throwable may have a cause is that the class that
throws it is built atop a lower layered abstraction, and an operation on
the upper layer fails due to a failure in the lower layer.
It would be bad
design to let the throwable thrown by the lower layer propagate outward, as
it is generally unrelated to the abstraction provided by the upper layer.
Further, doing so would tie the API of the upper layer to the details of
its implementation, assuming the lower layer&s exception was a checked
exception.
Throwing a &wrapped exception& (i.e., an exception containing a
cause) allows the upper layer to communicate the details of the failure to
its caller without incurring either of these shortcomings.
It preserves
the flexibility to change the implementation of the upper layer without
changing its API (in particular, the set of exceptions thrown by its
A second reason that a throwable may have a cause is that the method
that throws it must conform to a general-purpose interface that does not
permit the method to throw the cause directly.
For example, suppose
a persistent collection conforms to the
Collection interface, and that its persistence is implemented atop
Suppose the internals of the add method
can throw an IOException.
The implementation
can communicate the details of the IOException to its caller
while conforming to the Collection interface by wrapping the
IOException in an appropriate unchecked exception.
specification for the persistent collection should indicate that it is
capable of throwing such exceptions.)
A cause can be associated with a throwable in two ways: via a
constructor that takes the cause as an argument, or via the
New throwable classes that
wish to allow causes to be associated with them should provide constructors
that take a cause and delegate (perhaps indirectly) to one of the
Throwable constructors that takes a cause.
For example:
lowLevelOp();
} catch (LowLevelException le) {
throw new HighLevelException(le);
// Chaining-aware constructor
Because the initCause method is public, it allows a cause to be
associated with any throwable, even a &legacy throwable& whose
implementation predates the addition of the exception chaining mechanism to
Throwable. For example:
lowLevelOp();
} catch (LowLevelException le) {
throw (HighLevelException)
new HighLevelException().initCause(le);
// Legacy constructor
Prior to release 1.4, there were many throwables that had their own
non-standard exception chaining mechanisms (
All of these throwables have been retrofitted to
use the standard exception chaining mechanism, while continuing to
implement their &legacy& chaining mechanisms for compatibility.
Further, as of release 1.4, many general purpose Throwable
classes (for example , ,
) have been retrofitted with constructors that take
This was not strictly necessary, due to the existence of the
initCause method, but it is more convenient and expressive to
delegate to a constructor that takes a cause.
By convention, class Throwable and its subclasses have two
constructors, one that takes no arguments and one that takes a
String argument that can be used to produce a detail message.
Further, those subclasses that might likely have a cause associated with
them should have two more constructors, one that takes a
Throwable (the cause), and one that takes a
String (the detail message) and a Throwable (the

Remaining lines represent data previously recorded by
the method . The format of this
information depends on the implementation, but the following
example may be regarded as typical:
java.lang.NullPointerException
at MyClass.mash(MyClass.java:9)
at MyClass.crunch(MyClass.java:6)
at MyClass.main(MyClass.java:3)
This example was produced by running the program:
class MyClass {
public static void main(String[] args) {
crunch(null);
static void crunch(int[] a) {
static void mash(int[] b) {
System.out.println(b[0]);
The backtrace for a throwable with an initialized, non-null cause
should generally include the backtrace for the cause.
The format
of this information depends on the implementation, but the following
example may be regarded as typical:
HighLevelException: MidLevelException: LowLevelException
at Junk.a(Junk.java:13)
at Junk.main(Junk.java:4)
Caused by: MidLevelException: LowLevelException
at Junk.c(Junk.java:23)
at Junk.b(Junk.java:17)
at Junk.a(Junk.java:11)
... 1 more
Caused by: LowLevelException
at Junk.e(Junk.java:30)
at Junk.d(Junk.java:27)
at Junk.c(Junk.java:21)
... 3 more
Note the presence of lines containing the characters &...&.
These lines indicate that the remainder of the stack trace for this
exception matches the indicated number of frames from the bottom of the
stack trace of the exception that was caused by this exception (the
&enclosing& exception).
This shorthand can greatly reduce the length
of the output in the common case where a wrapped exception is thrown
from same method as the &causative exception& is caught.

Returns an array of stack trace elements,
each representing one stack frame.
The zeroth element of the array
(assuming the array&s length is non-zero) represents the top of the
stack, which is the last method invocation in the sequence.
Typically,
this is the point at which this throwable was created and thrown.
The last element of the array (assuming the array&s length is non-zero)
represents the bottom of the stack, which is the first method invocation
in the sequence.
Some virtual machines may, under some circumstances, omit one
or more stack frames from the stack trace.
In the extreme case,
a virtual machine that has no stack trace information concerning
this throwable is permitted to return a zero-length array from this
Generally speaking, the array returned by this method will
contain one element for every frame that would be printed by
