构造器详细资料

IllegalArgumentException

public IllegalArgumentException()

Constructs an IllegalArgumentException with no detail message.

IllegalArgumentException

public IllegalArgumentException(String s)

Constructs an IllegalArgumentException with the specified detail message.

参数:

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.

参数:

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.)

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).

参数:

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.)
