An object is subject to GARBAGE collection when it becomes UNREACHABLE to the PROGRAM in which it is USED.

An object is subject to garbage collection when it becomes unreachable to the program in which it is used.

An unreachable object may BECOME REACHABLE again. This can happen when the object's finalize() METHOD is INVOKED and the object performs an operation which CAUSES it to become accessible to reachable objects.

When an exception is thrown WITHIN the BODY of a try statement, the CATCH clauses of the try statement are examined in the order in which they appear. The first catch CLAUSE that is capable of handling the exception is executed. The remaining catch clauses are IGNORED.

Numeric PROMOTION is the conversion of a smaller numeric type to a larger numeric type, so that integer and floating-point operations may take place. In numerical promotion, byte, char, and SHORT VALUES are converted to int values. The int values are also converted to LONG values, if necessary. The long and float values are converted to double values, as required.

An abstract class may not be declared as final.

A THREAD can enter the waiting state by INVOKING its sleep() method, by blocking on I/O, by unsuccessfully attempting to acquire an object's LOCK, or by invoking an object's wait() method. It can ALSO enter the waiting state by invoking its (deprecated) SUSPEND() method.

ANSWER :A LAYOUT MANAGER is an object that is used to organize components in a CONTAINER.

An uncaught exception results in the uncaughtException() METHOD of the THREAD's ThreadGroup being INVOKED, which eventually results in the TERMINATION of the program in which it is THROWN.

An uncaught exception results in the uncaughtException() method of the thread's ThreadGroup being invoked, which eventually results in the termination of the program in which it is thrown.

So they can be INVOKED as if they are a MATHEMATICAL CODE LIBRARY.

The JDK 1.02 EVENT model uses an event inheritance or bubbling approach. In this model, components are REQUIRED to handle their own events. If they do not handle a particular event, the event is inherited by (or bubbled up to) the component's container. The container then either handles the event or it is bubbled up to its container and so on, until the highest-level container has been tried.

In the event-delegation model, SPECIFIC objects are designated as event handlers for GUI components. These objects implement event-listener interfaces. The event-delegation model is more efficient than the event-inheritance model because it ELIMINATES the processing required to support the bubbling of unhandled events.
