Inherited Methods

From class java.lang.Throwable

final void	addSuppressed(Throwable throwable) Adds `throwable` to the list of throwables suppressed by this.
Throwable	fillInStackTrace() Records the stack trace from the point where this method has been called to this `Throwable`.
Throwable	getCause() Returns the cause of this `Throwable`, or `null` if there is no cause.
String	getLocalizedMessage() Returns the detail message which was provided when this `Throwable` was created.
String	getMessage() Returns the detail message which was provided when this `Throwable` was created.
StackTraceElement[]	getStackTrace() Returns a clone of the array of stack trace elements of this `Throwable`.
final Throwable[]	getSuppressed() Returns the throwables suppressed by this.
Throwable	initCause(Throwable throwable) Initializes the cause of this `Throwable`.
void	printStackTrace(PrintStream err) Writes a printable representation of this `Throwable`'s stack trace to the given print stream.
void	printStackTrace(PrintWriter err) Writes a printable representation of this `Throwable`'s stack trace to the specified print writer.
void	printStackTrace() Writes a printable representation of this `Throwable`'s stack trace to the `System.err` stream.
void	setStackTrace(StackTraceElement[] trace) Sets the array of stack trace elements.
String	toString() Returns a string containing a concise, human-readable description of this object.

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Constructors

public AssertionError ()

Added in API level 1

Constructs a new AssertionError with no message.

public AssertionError (String detailMessage, Throwable cause)

Added in API level 19

Constructs a new AssertionError with the given detail message and cause.

Parameters
`detailMessage`	`String`
`cause`	`Throwable`

public AssertionError (Object detailMessage)

Added in API level 1

Constructs a new AssertionError with a message based on calling valueOf(Object) with the specified object. If the object is an instance of Throwable, then it also becomes the cause of this error.

Parameters
`detailMessage`	`Object`: the object to be converted into the detail message and optionally the cause.

public AssertionError (boolean detailMessage)

Added in API level 1

Constructs a new AssertionError with a message based on calling valueOf(boolean) with the specified boolean value.

Parameters
`detailMessage`	`boolean`: the value to be converted into the message.

public AssertionError (char detailMessage)

Added in API level 1

Constructs a new AssertionError with a message based on calling valueOf(char) with the specified character value.

Parameters
`detailMessage`	`char`: the value to be converted into the message.

public AssertionError (int detailMessage)

Added in API level 1

Constructs a new AssertionError with a message based on calling valueOf(int) with the specified integer value.

Parameters
`detailMessage`	`int`: the value to be converted into the message.

public AssertionError (long detailMessage)

Added in API level 1

Constructs a new AssertionError with a message based on calling valueOf(long) with the specified long value.

Parameters
`detailMessage`	`long`: the value to be converted into the message.

public AssertionError (float detailMessage)

Added in API level 1

Constructs a new AssertionError with a message based on calling valueOf(float) with the specified float value.

Parameters
`detailMessage`	`float`: the value to be converted into the message.

public AssertionError (double detailMessage)

Added in API level 1

Constructs a new AssertionError with a message based on calling valueOf(double) with the specified double value.

Parameters
`detailMessage`	`double`: the value to be converted into the message.
