All Implemented Interfaces:

Serializable

public exception IllegalStateException
extends RuntimeException

Signals that a method has been invoked at an illegal or inappropriate time. In other words, the Java environment or Java application is not in an appropriate state for the requested operation.

IllegalStateException

public IllegalStateException()

Constructs an IllegalStateException with no detail message. A detail message is a String that describes this particular exception.

IllegalStateException

public IllegalStateException(String s)

Constructs an IllegalStateException with the specified detail message. A detail message is a String that describes this particular exception.

Parameters:

s - the String that contains a detailed message

IllegalStateException

public IllegalStateException(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 {@link Throwable#getMessage()} method).

cause - the cause (which is saved for later retrieval by the {@link Throwable#getCause()} method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

IllegalStateException

public IllegalStateException(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, {@link java.security.PrivilegedActionException}).

Parameters:

cause - the cause (which is saved for later retrieval by the {@link Throwable#getCause()} method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
