public Throwable getCause()
nullif the cause is nonexistent or unknown. (The cause is the throwable that caused this throwable to get thrown.)
This implementation returns the cause that was supplied via one of
the constructors requiring a Throwable, or that was set after
creation with the
Throwable.initCause(Throwable) method. While it is
typically unnecessary to override this method, a subclass can override
it to return a cause set by some other means. This is appropriate for
a "legacy chained throwable" that predates the addition of chained
exceptions to Throwable. Note that it is not
necessary to override any of the PrintStackTrace methods,
all of which invoke the getCause method to determine the
cause of a throwable.
nullif the cause is nonexistent or unknown.
