FormatFlagsConversionMismatchException Unchecked exception thrown when a conversion and flag are incompatible. IllegalFormatCodePointException Unchecked exception thrown when a character with an invalid Unicode code point as defined by Character.isValidCodePoint is passed to the Formatter.

IllegalArgumentException(s: String!) Constructs an IllegalArgumentException with the specified detail message.
IllegalArgumentException(message: String!, cause: Throwable!) Constructs a new exception with the specified detail message and cause.
IllegalArgumentException(cause: Throwable!) 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).

Public constructors

IllegalArgumentException

Added in API level 1

IllegalArgumentException()

Constructs an IllegalArgumentException with no detail message.

IllegalArgumentException

Added in API level 1

IllegalArgumentException(s: String!)

Constructs an IllegalArgumentException with the specified detail message.

Parameters
s	String!: the detail message.

IllegalArgumentException

Added in API level 1

IllegalArgumentException(
    message: String!, 
    cause: Throwable!)

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	String!: the detail message (which is saved for later retrieval by the Throwable.getMessage() method).
cause	Throwable!: 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

Added in API level 1

IllegalArgumentException(cause: Throwable!)

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, ).

Parameters
cause	Throwable!: 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.)
