built-in exception						all instance variables of all objects of its class	when a built-in exception is raised an instance of the exception's class is created that contains information about the problem causing the exception				any entity to which you can associate properties and behaviour	instance methods and instance variables from the class to which it belongs all that class's superclasses																		state that is maintained in its variables		distinct from every other object even if they contain the same data
checked exception						all instance variables of all objects of its class	if a checked exception may be thrown by a method then that method must have a throws clause that mentions the class of that exception or one of the superclasses of the class of that exception				any entity to which you can associate properties and behaviour	instance methods and instance variables from the class to which it belongs all that class's superclasses																		state that is maintained in its variables	A kind of exception that Java checks for at compile time and for which a Java program contains handlers	distinct from every other object even if they contain the same data
programmer-created exception class	bold = mandatory italic = non-terminal normal font = optional	0 or more methods to the methods it inherits from its superclass	a list of variables, called instance variables, corresponding to data that will be present in each instance	its members from access by other classes or objects using an access modifier	the internals of a computer system such as 'Record', 'Table', 'Data', 'Structure', or 'Information'	any public class in other packages	if an exception is raised in a statement that is not in a try block with an appropriate catch statement then Java looks to see if the caller of the current method is within a try block that has an appropriate catch block if this is not successful, Java looks at callers right up to the main program otherwise Java reports an error if it has not been able to find any suitable catch block	only one superclass	implementation for all its instance methods unless the class is abstract	its own source file	several similar objects	behaviour from its superclass	data associated with each object		public class HelloWorld { public static void main(String[] args) { System.out.println("Hello World!"); } }	create an instance of it	more than one interface	a package	elements as follows: class variables instance variables constructors the most important public methods methods that are simply used to access variables private methods	Object class	a class type whose instances are the values of the class type	1 class definition	public or private or protected	an implements clause to declare that it contains methods for each of the operations specified by the interface	class classname { // declarations of variables // declarations of constructors // declarations of other methods with public ones first }	methods that are inherited from the class's superclass	1 named package rather than the default package	reusability modularity	constructor	a unique name since somebody in the future might want to import the packages containing both classes and hence create a name clash		the unit of data abstraction in an object-oriented program
unchecked exception						all instance variables of all objects of its class	if an exception is raised in a statement that is not in a try block with an appropriate catch statement then Java looks to see if the caller of the current method is within a try block that has an appropriate catch block if this is not successful, Java looks at callers right up to the main program otherwise Java reports an error if it has not been able to find any suitable catch block				any entity to which you can associate properties and behaviour	instance methods and instance variables from the class to which it belongs all that class's superclasses																		state that is maintained in its variables	An exception that is not checked , which is of the class RuntimeException and its subclasses, or of the class Error and its subclasses	distinct from every other object even if they contain the same data
