    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.

Since:
  JDK1.0
See Also:
  `Error`, Serialized Form

Constructor Summary
`Exception()` Constructs a new exception with `null` as its detail message.
`Exception(String message)` Constructs a new exception with the specified detail message.
`Exception(String message, Throwable cause)` Constructs a new exception with the specified detail message and cause.
`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`).

Method Summary

Methods inherited from class java.lang.Throwable
`fillInStackTrace, getCause, getLocalizedMessage, getMessage, getStackTrace, initCause, printStackTrace, printStackTrace, printStackTrace, setStackTrace, toString`

Methods inherited from class java.lang.Object
`clone, equals, finalize, getClass, hashCode, notify, notifyAll, wait, wait, wait`

Constructor Detail

### 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.)
  Since:
    1.4

### 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.)
  Since:
    1.4
