`String`	`getLocalizedMessage()`	Creates a localized description of this throwable.
`StackTraceElement[]`	`getStackTrace()`	Provides programmatic access to the stack trace information printed by `Throwable.printStackTrace()`.
`final Throwable[]`	`getSuppressed()`	Returns an array containing all of the exceptions that were suppressed, typically by the `try`-with-resources statement, in order to deliver this exception.
`Throwable`	`initCause(Throwable cause)`	Initializes the cause of this throwable to the specified value.

`void`	`printStackTrace(PrintStream s)`	Prints this throwable and its backtrace to the specified print stream.
`void`	`printStackTrace(PrintWriter s)`	Prints this throwable and its backtrace to the specified print writer.
`void`	`setStackTrace(StackTraceElement[] stackTrace)`	Sets the stack trace elements that will be returned by `Throwable.getStackTrace()` and printed by `Throwable.printStackTrace()` and related methods.

`final Class<?>`	`getClass()`	Returns the runtime class of this `Object`.
`int`	`hashCode()`	Returns a hash code value for this object.
`final void`	`notify()`	Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()`	Wakes up all threads that are waiting on this object's monitor.
`final void`	`wait()`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
`final void`	`wait(long timeoutMillis)`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
