InternalError

AI-generated Key Takeaways

• InternalError signals an unexpected, unrecoverable error within the Java Virtual Machine.

• It's a subclass of VirtualMachineError and is thrown when the JVM encounters an internal problem.

• It can be constructed with an optional detail message, cause, or both to provide more context.

• InternalError inherits methods from Throwable for stack trace and exception handling.

• Developers typically do not handle InternalError directly, as it signifies a critical JVM issue.

public class InternalError extends VirtualMachineError

Known Direct Subclasses ZipError ZipError Signals that an unrecoverable error has occurred.

Thrown to indicate some unexpected internal error has occurred in the Java Virtual Machine.

Public Constructor Summary

	InternalError() Constructs an InternalError with no detail message.
	InternalError(String message) Constructs an InternalError with the specified detail message.
	InternalError(String message, Throwable cause) Constructs an InternalError with the specified detail message and cause.
	InternalError(Throwable cause) Constructs an InternalError 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 Method Summary

From class java.lang.Throwable

synchronized final void	addSuppressed(Throwable exception) Appends the specified exception to the exceptions that were suppressed in order to deliver this exception.
synchronized Throwable	fillInStackTrace() Fills in the execution stack trace.
synchronized Throwable	getCause() Returns the cause of this throwable or null if the cause is nonexistent or unknown.
String	getLocalizedMessage() Creates a localized description of this throwable.
String	getMessage() Returns the detail message string of this throwable.
StackTraceElement[]	getStackTrace() Provides programmatic access to the stack trace information printed by printStackTrace().
synchronized final Throwable[]	getSuppressed() Returns an array containing all of the exceptions that were suppressed, typically by the try-with-resources statement, in order to deliver this exception.
synchronized Throwable	initCause(Throwable cause) Initializes the cause of this throwable to the specified value.
void	printStackTrace() Prints this throwable and its backtrace to the standard error stream.
void	printStackTrace(PrintWriter s) Prints this throwable and its backtrace to the specified print writer.
void	printStackTrace(PrintStream s) Prints this throwable and its backtrace to the specified print stream.
void	setStackTrace(StackTraceElement[] stackTrace) Sets the stack trace elements that will be returned by getStackTrace() and printed by printStackTrace() and related methods.
String	toString() Returns a short description of this throwable.

From class java.lang.Object

Object	clone() Creates and returns a copy of this Object.
boolean	equals(Object obj) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of Class that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait(long timeout, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait(long timeout) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.

Public Constructors

public InternalError ()

Constructs an InternalError with no detail message.

public InternalError (String message)

Constructs an InternalError with the specified detail message.

Parameters

message	the detail message.

public InternalError (String message, Throwable cause)

Constructs an InternalError with the specified detail message and cause.

Note that the detail message associated with cause is not automatically incorporated in this error'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.)

public InternalError (Throwable cause)

Constructs an InternalError with the specified cause and a detail message of (cause==null ? null : cause.toString()) (which typically contains the class and detail message of cause).

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.)
