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:

Constructor:
public Exception() { super(); } Constructs a new exception with {@code null} as its detail message. The cause is not initialized, and may subsequently be initialized by a call to #initCause .
public Exception(String message) { super(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) { super(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) { super(message, 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) { super(message, cause, enableSuppression, 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` -

 public Exception() {
        super();
}

Constructs a new exception with {@code null} as its detail message. The cause is not initialized, and may subsequently be initialized by a call to

#initCause

 public Exception(String message) {
        super(message);
}

#initCause

Parameters:

message - the detail message. The detail message is saved for later retrieval by the #getMessage() method.

 public Exception(Throwable cause) {
        super(cause);
}

(cause==null ? null : cause.toString())

cause

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) {
        super(message, 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) {
        super(message, cause, enableSuppression, 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
