Constructor:

Constructor:
public IOException() { super(); } Constructs an {@code IOException} with {@code null} as its error detail message.
public IOException(String message) { super(message); } Constructs an {@code IOException} with the specified detail message. Parameters: `message` - The detail message (which is saved for later retrieval by the #getMessage() method)
public IOException(Throwable cause) { super(cause); } Constructs an {@code IOException} with the specified cause and a detail message of {@code (cause==null ? null : cause.toString())} (which typically contains the class and detail message of {@code cause}). This constructor is useful for IO exceptions that are little more than wrappers for other throwables. 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: `1.6` -
public IOException(String message, Throwable cause) { super(message, cause); } Constructs an {@code IOException} with the specified detail message and cause. Note that the detail message associated with {@code cause} is not automatically incorporated into 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: `1.6` -

 public IOException() {
                     
        super();
}

Constructs an {@code IOException} with {@code null} as its error detail message.

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

Constructs an {@code IOException} with the specified detail message.

Parameters:

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

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

Constructs an {@code IOException} with the specified cause and a detail message of {@code (cause==null ? null : cause.toString())} (which typically contains the class and detail message of {@code cause}). This constructor is useful for IO exceptions that are little more than wrappers for other throwables.

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: 1.6 -

 public IOException(String message,
    Throwable cause) {
        super(message, cause);
}

Note that the detail message associated with {@code cause} is not automatically incorporated into 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: 1.6 -
