public class IllegalArgumentException extends RuntimeException {
Constructs an IllegalArgumentException with no detail message.
/** * Constructs an <code>IllegalArgumentException</code> with no * detail message. */
public IllegalArgumentException() { super(); }
Constructs an IllegalArgumentException with the specified detail message.
Params:
  • s – the detail message.
/** * Constructs an <code>IllegalArgumentException</code> with the * specified detail message. * * @param s the detail message. */
public IllegalArgumentException(String s) { super(s); }
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.

Params:
  • 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

public IllegalArgumentException(String message, Throwable cause) { super(message, 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).
Params:
  • 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
