It uses those low order bytes of the result that can fit into the size of the type allowed by the operation.

The List interface provides support for ordered collections of objects.

The Collections API is a set of classes and interfaces that support operations on collections of objects.

The window, Frame and Dialog classes use a border layout as their default layout in Java Programming.

The setLayout() method is used to specify a container's layout in Java Programming.

The preferred size of a component is the minimum component size that will allow the component to display normally.

The Panel and Applet classes use the FlowLayout as their default layout.

The stop(), suspend() and resume() methods have been deprecated in JDK 1.2.

Yes, a lock can be acquired on a class. This lock is acquired on the class's Class object.

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.

With respect to multithreading, synchronization is the capability to control the access of multiple threads to shared resources. Without synchronization, it is possible for one thread to modify a shared object while another thread is in the process of using or updating that object's value. This often causes dirty data and leads to significant errors.

Synchronized methods are methods that are used to control access to an object. A thread only executes a synchronized method after it has acquired the lock for the method's object or class. Synchronized statements are similar to synchronized methods. A synchronized statement can only be executed after a thread has acquired the lock for the object or class referenced in the synchronized statement.

Objects that subclass the Observable class maintain a list of observers. When an Observable object is updated it invokes the update() method of each of its observers to notify the observers that it has changed state. The Observer interface is implemented by objects that observe Observable objects.

The high-level thread states are ready, running, waiting, and dead.

It must provide all of the methods in the interface and identify the interface in its implements clause.

The wait(),notify(), and notifyAll() methods are used to provide an efficient way for threads to communicate each other in Java Programming.

The Locale class is used to tailor program output to the conventions of a particular geographic, political, or cultural region.

The finally clause is used to provide the capability to execute code no matter whether or not an exception is thrown or caught.

The purpose of the Runtime class is to provide access to the Java runtime system in Java Programming.

If an expression involving the Boolean & operator is evaluated, both operands are evaluated. Then the & operator is applied to the operand. When an expression involving the && operator is evaluated, the first operand is evaluated. If the first operand returns a value of true then the second operand is evaluated. The && operator is then applied to the first and second operands. If the first operand evaluates to false, the evaluation of the second operand is skipped.

Operator & has no chance to skip both sides evaluation and && operator does. If asked why, give details as above.
