VirtualMachineError

AI-generated Key Takeaways

• VirtualMachineError is a subclass of Error indicating critical issues within the Java Virtual Machine, such as resource exhaustion or internal failures, requiring immediate attention as the JVM is unable to continue normal operation.

• This error has direct subclasses like OutOfMemoryError, StackOverflowError, signifying specific critical situations, and indirect ones such as ZipError for specialized scenarios like corrupted ZIP files, all arising from serious, unrecoverable JVM conditions.

• Several constructors are available to create VirtualMachineError instances with optional detail messages and underlying causes, aiding developers in understanding and addressing the encountered error's context.

• VirtualMachineError inherits methods from its superclasses that allow developers to access the error message, stack trace, and cause, offering valuable insight for debugging and resolution.

public abstract class VirtualMachineError extends Error

Known Direct Subclasses InternalError, OutOfMemoryError, StackOverflowError, UnknownError InternalError Thrown to indicate some unexpected internal error has occurred in the Java Virtual Machine.  OutOfMemoryError Thrown when the Java Virtual Machine cannot allocate an object because it is out of memory, and no more memory could be made available by the garbage collector.  StackOverflowError Thrown when a stack overflow occurs because an application recurses too deeply.  UnknownError Thrown when an unknown but serious exception has occurred in the Java Virtual Machine.

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

Thrown to indicate that the Java Virtual Machine is broken or has run out of resources necessary for it to continue operating.

Public Constructor Summary

	VirtualMachineError() Constructs a VirtualMachineError with no detail message.
	VirtualMachineError(String message) Constructs a VirtualMachineError with the specified detail message.
	VirtualMachineError(String message, Throwable cause) Constructs a VirtualMachineError with the specified detail message and cause.
	VirtualMachineError(Throwable cause) Constructs an a VirtualMachineError 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 VirtualMachineError ()

Constructs a VirtualMachineError with no detail message.

public VirtualMachineError (String message)

Constructs a VirtualMachineError with the specified detail message.

Parameters

message	the detail message.

public VirtualMachineError (String message, Throwable cause)

Constructs a VirtualMachineError 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 VirtualMachineError (Throwable cause)

Constructs an a VirtualMachineError 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.)
