Constructor Detail

IllegalArgumentException

public IllegalArgumentException()
Constructs an IllegalArgumentException with no detail message.


IllegalArgumentException

public IllegalArgumentException(String s)
Constructs an IllegalArgumentException with the specified detail message.

Parameters:
s - the detail message.

IllegalArgumentException

public IllegalArgumentException(String message,
                                Throwable cause)
Constructs a new exception with the specified detail message and cause.

Note that the detail message associated with cause is not automatically incorporated in 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:
1.5

IllegalArgumentException

public IllegalArgumentException(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, PrivilegedActionException).

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.)
Since:
1.5
