public class: Exception [javadoc | source]
java.lang.Object
   java.lang.Throwable
      java.lang.Exception

All Implemented Interfaces:
    Serializable

The class {@code Exception} and its subclasses are a form of {@code Throwable} that indicates conditions that a reasonable application might want to catch.

The class {@code 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 {@code throws} clause if they can be thrown by the execution of the method or constructor and propagate outside the method or constructor boundary.

Field Summary
static final  long serialVersionUID     
Constructor:
 public 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 #initCause .
    Parameters:
    message - the detail message. The detail message is saved for later retrieval by the #getMessage() method.
 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, java.security.PrivilegedActionException ).
    Parameters:
    cause - the cause (which is saved for later retrieval by the #getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
    since: 1.4 -
 public Exception(String message,
    Throwable cause) 
    Constructs a new exception with the specified detail message and cause.

    Note that the detail message associated with {@code cause} is not automatically incorporated in this exception's detail message.

    Parameters:
    message - the detail message (which is saved for later retrieval by the #getMessage() method).
    cause - the cause (which is saved for later retrieval by the #getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
    since: 1.4 -
 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 {@code 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
    since: 1.7 -
