DuplicateFormatFlagsException	Unchecked exception thrown when duplicate flags are provided in the format specifier.
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 `isValidCodePoint(int)` is passed to the `Formatter`.
IllegalFormatConversionException	Unchecked exception thrown when the argument corresponding to the format specifier is of an incompatible type.
IllegalFormatFlagsException	Unchecked exception thrown when an illegal combination flags is given.
IllegalFormatPrecisionException	Unchecked exception thrown when the precision is a negative value other than `-1`, the conversion does not support a precision, or the value is otherwise unsupported.
IllegalFormatWidthException	Unchecked exception thrown when the format width is a negative value other than `-1` or is otherwise unsupported.
MissingFormatArgumentException	Unchecked exception thrown when there is a format specifier which does not have a corresponding argument or if an argument index refers to an argument that does not exist.
MissingFormatWidthException	Unchecked exception thrown when the format width is required.
UnknownFormatConversionException	Unchecked exception thrown when an unknown conversion is given.
UnknownFormatFlagsException	Unchecked exception thrown when an unknown flag is given.

Class Overview

Thrown to indicate that a method has been passed an illegal or inappropriate argument.

Summary

Public Constructors
	IllegalArgumentException() Constructs an `IllegalArgumentException` with no detail message.
	IllegalArgumentException(String s) Constructs an `IllegalArgumentException` with the specified detail message.
	IllegalArgumentException(String message, Throwable cause) Constructs a new exception with the specified detail message and cause.
	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`).

Inherited Methods

From class java.lang.Throwable

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public Constructors

public IllegalArgumentException ()

Constructs an IllegalArgumentException with no detail message.

public IllegalArgumentException (String s)

Constructs an IllegalArgumentException with the specified detail message.

Parameters

s	the detail message.

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 `getMessage()` method).
cause	the cause (which is saved for later retrieval by the `getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.)

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 `getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.)
