Constructor Detail

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 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

---

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, PrivilegedActionException).

Parameters:

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
