Java

A native method is a method that is implemented in a language other than Java.

The purpose of finalization is to give an unreachable object the opportunity to perform any cleanup processing before the object is garbage collected.

The Canvas, Frame, Panel, and Applet classes support painting.

Under preemptive scheduling, the highest priority task executes until it enters the waiting or dead states or a higher priority task comes into existence. Under time slicing, a task executes for a predefined slice of time and then reenters the pool of ready tasks. The scheduler then determines which task should execute next, based on priority and other factors.

No, it doesn’t. It is possible for programs to use up memory resources faster than they are garbage collected. It is also possible for programs to create objects that are not subject to garbage collection

The sizeof operator is not a keyword in Java Programming.

When a task invokes its yield() method, it returns to the ready state. When a task invokes its sleep() method, it returns to the waiting state.

Unicode requires 16 bits and ASCII require 7 bits. Although the ASCII character set uses only 7 bits, it is usually represented as 8 bits. UTF-8 represents characters using 8, 16, and 18 bit patterns. UTF-16 uses 16-bit and larger bit patterns.

Wrapped classes are classes that allow primitive types to be accessed as objects.

The Iterator interface is used to step through the elements of a Collection.

A protected method may only be accessed by classes or interfaces of the same package or by subclasses of the class in which it is declared.

A (non-local) inner class may be declared as public, protected, private, static, final, or abstract.

The Vector class in Java Programming provides the capability to implement a growable array of objects

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

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

The List interface provides support for ordered collections of objects.

When a thread terminates its processing, it enters the dead state.

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

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

The primitive types are byte, char, short, int, long, float, double, and boolean.
