public classExceptionextendsThrowable
The classException and its subclasses are a form ofThrowable that indicates conditions that a reasonable application might want to catch.

The classException and any subclasses that are not also subclasses ofRuntimeException arechecked exceptions. Checked exceptions need to be declared in a method or constructor'sthrows clause if they can be thrown by the execution of the method or constructor and propagate outside the method or constructor boundary.

  • Constructor Details

    • Exception

      public Exception()
      Constructs a new exception withnull as its detail message. The cause is not initialized, and may subsequently be initialized by a call toThrowable.initCause(java.lang.Throwable).

    • Exception

      public Exception(String message)
      Constructs a new 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.

    • Exception

      public Exception(String message,Throwable cause)
      Constructs a new exception with the specified detail message and cause.

      Note that the detail message associated withcause isnot automatically incorporated in this 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). (Anull value is permitted, and indicates that the cause is nonexistent or unknown.)

    • Exception

      public Exception(Throwable cause)
      Constructs a new 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 exceptions that are little more than wrappers for other throwables (for example,PrivilegedActionException).
      Parameters:
      cause - the cause (which is saved for later retrieval by theThrowable.getCause() method). (Anull value is permitted, and indicates that the cause is nonexistent or unknown.)

      1.4

    • Exception

      protected Exception(String message,Throwable cause, boolean enableSuppression, boolean writableStackTrace)
      Constructs a new 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. (Anull value 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
