RuntimeException
is the superclass of those
exceptions that can be thrown during the normal operation of the
Java Virtual Machine.
RuntimeException
and its subclasses are unchecked
exceptions. Unchecked exceptions do not need to be
declared in a method or constructor's throws
clause if they
can be thrown by the execution of the method or constructor and
propagate outside the method or constructor boundary.

RuntimeException(String message)
Constructs a new runtime exception with the specified detail message. |

RuntimeException(String message, Throwable cause)
Constructs a new runtime exception with the specified detail message and cause. |

RuntimeException(Throwable cause)
Constructs a new runtime exception with the specified cause and a detail message of (cause==null ? null : cause.toString()) (which typically contains the class and detail message of cause). |

RuntimeException ()
Constructs a new runtime exception with null
as its
detail message. The cause is not initialized, and may subsequently be
initialized by a call to initCause(Throwable)
.
RuntimeException (String message)
Constructs a new runtime exception with the specified detail message.
The cause is not initialized, and may subsequently be initialized by a
call to initCause(Throwable)
.
Parameters | |
---|---|
message |
String :
the detail message. The detail message is saved for
later retrieval by the getMessage() method.
|
RuntimeException (String message, Throwable cause)
Constructs a new runtime exception with the specified detail message and cause.
Note that the detail message associated with
cause
is not automatically incorporated in
this runtime exception's detail message.
Parameters | |
---|---|
message |
String :
the detail message (which is saved for later retrieval
by the getMessage() method). |
cause |
Throwable :
the cause (which is saved for later retrieval by the
getCause() method). (A null value is
permitted, and indicates that the cause is nonexistent or
unknown.) |
RuntimeException (Throwable cause)
Constructs a new runtime exception with the specified cause and a detail message of (cause==null ? null : cause.toString()) (which typically contains the class and detail message of cause). This constructor is useful for runtime exceptions that are little more than wrappers for other throwables.
Parameters | |
---|---|
cause |
Throwable :
the cause (which is saved for later retrieval by the
getCause() method). (A null value is
permitted, and indicates that the cause is nonexistent or
unknown.) |
RuntimeException (String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace)
Constructs a new runtime exception with the specified detail message, cause, suppression enabled or disabled, and writable stack trace enabled or disabled.
Parameters | |
---|---|
message |
String :
the detail message. |
cause |
Throwable :
the cause. (A null value is permitted,
and indicates that the cause is nonexistent or unknown.) |
enableSuppression |
boolean :
whether or not suppression is enabled
or disabled |
writableStackTrace |
boolean :
whether or not the stack trace should
be writable |
