Constructor Detail
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 theThrowable.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 theThrowable.getMessage()
method) -
cause
- The cause (which is saved for later retrieval by theThrowable.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 theThrowable.getCause()
method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.) - Since:
- 1.6
