public class Exception extends Throwable
The class Exception and its subclasses are a form of Throwable that indicates conditions that a reasonable application might want to catch.

The class Exception and any subclasses that are not also subclasses of RuntimeException are checked exceptions. Checked exceptions 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

    • Exception

      public Exception()
      Constructs a new exception with null as its detail message. The cause is not initialized, and may subsequently be initialized by a call to Throwable.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 to Throwable.initCause(java.lang.Throwable).
      Parameters:
      message - the detail message. The detail message is saved for later retrieval by the Throwable.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 with cause is not automatically incorporated in this 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 null 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 of cause). 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 the Throwable.getCause() method). (A null 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. (A null 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
