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.

Constructor Details- 
RuntimeExceptionpublic RuntimeException()Constructs a new runtime exception withnullas its detail message. The cause is not initialized, and may subsequently be initialized by a call toThrowable.initCause(java.lang.Throwable).
- 
RuntimeExceptionConstructs a new runtime exception with the specified detail message. The cause is not initialized, and may subsequently be initialized by a call toThrowable.initCause(java.lang.Throwable).- Parameters:
- message- the detail message. The detail message is saved for later retrieval by the- Throwable.getMessage()method.
 
- 
RuntimeExceptionConstructs a new runtime exception with the specified detail message and cause.Note that the detail message associated with causeis not automatically incorporated in this runtime exception's detail message.- Parameters:
- message- the detail message (which is saved for later retrieval by the- Throwable.getMessage()method).
- cause- the cause (which is saved for later retrieval by the- Throwable.getCause()method). (A- nullvalue is permitted, and indicates that the cause is nonexistent or unknown.)
- Since:
- 1.4
 
- 
RuntimeExceptionConstructs 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 ofcause). This constructor is useful for runtime exceptions that are little more than wrappers for other throwables.- Parameters:
- cause- the cause (which is saved for later retrieval by the- Throwable.getCause()method). (A- nullvalue is permitted, and indicates that the cause is nonexistent or unknown.)
- Since:
- 1.4
 
- 
RuntimeExceptionprotected 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- the detail message.
- cause- the cause. (A- nullvalue is permitted, and indicates that the cause is nonexistent or unknown.)
- enableSuppression- whether or not suppression is enabled or disabled
- writableStackTrace- whether or not the stack trace should be writable
- Since:
- 1.7
