Constructor Details

IOException

public IOException()

Constructs an IOException with null as its error detail message.

IOException

public IOException(String message)

Constructs an IOException with the specified detail message.

Parameters:

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

IOException

public IOException(String message,
 Throwable cause)

Constructs an IOException with the specified detail message and cause.

Note that the detail message associated with cause is not automatically incorporated into 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:

1.6

IOException

public IOException(Throwable cause)

Constructs an IOException 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 IO exceptions that are little more than wrappers for other throwables.

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.)
