public classRuntimeExceptionextendsException
RuntimeExceptionis the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine.RuntimeExceptionand its subclasses areunchecked exceptions. Unchecked exceptions donot need to be declared in a method or constructor'sthrowsclause if they can be thrown by the execution of the method or constructor and propagate outside the method or constructor boundary.- Since:

Constructor Detail
RuntimeException
public 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).
RuntimeException
public 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 toThrowable.initCause(java.lang.Throwable).- Parameters:
message- the detail message. The detail message is saved for later retrieval by theThrowable.getMessage()method.
RuntimeException
public RuntimeException(String message,Throwable cause)
Constructs a new runtime exception with the specified detail message and cause.Note that the detail message associated with
causeisnot automatically incorporated in this runtime exception's detail message.- Parameters:
message- the detail message (which is saved for later retrieval by theThrowable.getMessage()method).cause- the cause (which is saved for later retrieval by theThrowable.getCause()method). (Anullvalue is permitted, and indicates that the cause is nonexistent or unknown.)- Since:
- 1.4
RuntimeException
public 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 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 theThrowable.getCause()method). (Anullvalue is permitted, and indicates that the cause is nonexistent or unknown.)- Since:
- 1.4
RuntimeException
protected 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. (Anullvalue is permitted, and indicates that the cause is nonexistent or unknown.)enableSuppression- whether or not suppression is enabled or disabledwritableStackTrace- whether or not the stack trace should be writable- Since:
- 1.7
