Class Overview

The superclass of all classes which can be thrown by the virtual machine. The two direct subclasses are recoverable exceptions (Exception) and unrecoverable errors (Error). This class provides common methods for accessing a string message which provides extra information about the circumstances in which the Throwable was created (basically an error message in most cases), and for saving a stack trace (that is, a record of the call stack at a particular point in time) which can be printed later.

A Throwable can also include a cause, which is a nested Throwable that represents the original problem that led to this Throwable. It is often used for wrapping various types of errors into a common Throwable without losing the detailed original error information. When printing the stack trace, the trace of the cause is included.

Parameters

detailMessage	the detail message for this `Throwable`.

public Throwable (String detailMessage, Throwable throwable)

Since: API Level 1

Constructs a new Throwable with the current stack trace, the specified detail message and the specified cause.

Parameters

detailMessage	the detail message for this `Throwable`.
throwable	the cause of this `Throwable`.

public Throwable (Throwable throwable)

Since: API Level 1

Constructs a new Throwable with the current stack trace and the specified cause.

Parameters

throwable	the cause of this `Throwable`.

Public Methods

public Throwable fillInStackTrace ()

Since: API Level 1

Records the stack trace from the point where this method has been called to this Throwable. This method is invoked by the Throwable constructors.

This method is public so that code (such as an RPC system) which catches a Throwable and then re-throws it can replace the construction-time stack trace with a stack trace from the location where the exception was re-thrown, by calling fillInStackTrace.

This method is non-final so that non-Java language implementations can disable VM stack traces for their language. Filling in the stack trace is relatively expensive. Overriding this method in the root of a language's exception hierarchy allows the language to avoid paying for something it doesn't need.

Returns

this Throwable instance.

public Throwable getCause ()

Since: API Level 1

Returns the cause of this Throwable, or null if there is no cause.

Returns

Throwable this Throwable's cause.

public String getLocalizedMessage ()

Since: API Level 1

Returns the extra information message which was provided when this Throwable was created. Returns null if no message was provided at creation time. Subclasses may override this method to return localized text for the message. Android returns the regular detail message.

Returns

this Throwable's localized detail message.

public String getMessage ()

Since: API Level 1

Returns the extra information message which was provided when this Throwable was created. Returns null if no message was provided at creation time.

Returns

this Throwable's detail message.

public StackTraceElement[] getStackTrace ()

Since: API Level 1

Returns the array of stack trace elements of this Throwable. Each StackTraceElement represents an entry in the call stack. The element at position 0 is the top of the stack, that is, the stack frame where this Throwable is thrown.

Returns

a copy of the array of StackTraceElements representing the call stack. Changes in the array obtained from this call will not change the call stack stored in this Throwable.

public Throwable initCause (Throwable throwable)

Since: API Level 1

Initializes the cause of this Throwable. The cause can only be initialized once.

Parameters

throwable	the cause of this `Throwable`.

Returns

this Throwable instance.

Throws

IllegalArgumentException	if `Throwable` is this object.
IllegalStateException	if the cause has already been initialized.

public void printStackTrace (PrintWriter err)

Since: API Level 1

Writes a printable representation of this Throwable's stack trace to the specified print writer. If the Throwable contains a cause, the method will be invoked recursively for the nested Throwable.

Parameters

err	the writer to write the stack trace on.

public void printStackTrace (PrintStream err)

Since: API Level 1

Writes a printable representation of this Throwable's stack trace to the specified print stream. If the Throwable contains a cause, the method will be invoked recursively for the nested Throwable.

Parameters

err	the stream to write the stack trace on.

public void printStackTrace ()

Since: API Level 1

Writes a printable representation of this Throwable's stack trace to the System.err stream.

public void setStackTrace (StackTraceElement[] trace)

Since: API Level 1

Sets the array of stack trace elements. Each StackTraceElement represents an entry in the call stack. A copy of the specified array is stored in this Throwable. will be returned by getStackTrace() and printed by printStackTrace().

Parameters

trace	the new array of `StackTraceElement`s. A copy of the array is stored in this `Throwable`, so subsequent changes to `trace` will not change the call stack stored in this `Throwable`.

Throws

NullPointerException	if any element in `trace` is `null`.

public String toString ()

Since: API Level 1

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

   getClass().getName() + '@' + Integer.toHexString(hashCode())

See Writing a useful toString method if you intend implementing your own toString method.

Returns

a printable representation of this object.
