and its subclasses are a form ofThrowable
that indicates conditions that a reasonable application might want to catch.ClassObject
is the root of the class hierarchy.RuntimeException
is the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine.TheString
class represents character strings.TheThrowable
class is the superclass of all errors and exceptions in the Java language. -
ClassDescriptionThrown to indicate that the code has attempted to cast an object to a subclass of which it is not an instance.Thrown when an application tries to load in a class through its string name using: The
forName
method in classClass
.An IllegalAccessException is thrown when an application tries to reflectively create an instance (other than an array), set or get a field, or invoke a method, but the currently executing method does not have access to the definition of the specified class, field, method or constructor.Thrown when an application tries to create an instance of a class using thenewInstance
method in classClass
, but the specified class object cannot be instantiated.ClassObject
is the root of the class hierarchy.TheString
class represents character strings.Indicates the warnings to be suppressed at compile time in the annotated element, and in all elements contained in the annotated element. -
