Once an object has been instantiated, we can use the dot operator to invoke its methods
Note: A method may return a value or not
String s = new String(“Hello");
int count = s.length();
System.out.println("Length of s is " + count);
In object-oriented programming, a class is a construct that is used to create instances of itself – referred to as class instances, class objects, instance objects or simply objects. A class defines constituent members which enable its instances to have state and behavior. Data field members (member variables or instance variables) enable a class instance to maintain state. Other kinds of members, especially methods, enable the behavior of class instances. Classes define the type of their instances....
Objectives: Explain how a small network of directly connected segments is created, configured and verified. In this activity, you will note how networks differ, both in size and in function. You will identify how networks provide different networking solutions based upon their cost, speed, ports, expandability, and manageability, related to the needs of a small-to-medium-sized business.
Objectives: Networks are made of many different components. In this activity, you will visualize how you are connected, through the Internet, to those places, people, or businesses with whom (or which) you interact on a daily basis. After reflection and sketching your home’s or school’s topology, you can draw conclusions about the Internet that you may not have thought of prior to this activity.
Objectives: Identify the common components of a network. In this activity, you will illustrate how concepts from Chapter 1 are applied to show how network devices connect to and throughout the Internet. After reflecting on your home or small-business topology, you will become familiar with using the device icons and knowledge needed to visualize network connectivity through the remaining network courses.
Objectives: Connect devices using wired and wireless media. In this activity, you will map your network cabling or technology type ideas to a physical topology. Because this chapter focuses on the network access layer, you should be able to prepare a basic physical model. No logical (IP addressing) schemes are required for this activity.
Object Oriented Programming - Lesson 3: Class Building Understand the application of object oriented principles in Java, Acquaint how to declare a class and its members, Data abstraction, Class building.
This book is meant to give you a head start on the changes from Visual Basic to
Visual Basic.NET (VB.NET). Most of the book assumes that you are comfortable
with Visual Basic 6.0 (VB6), so the book endeavors to be a quick introduction to the
major differences between VB6 and the new VB.NET.
I’ve been using Visual Basic since version 1.0. The most dramatic shift had been in
the move from VB3 to VB4, when class modules were introduced, and VB started on
its long, slow path to becoming object oriented.
Need to make sense of the many changes to Visual Basic for the new .NET platform? VB .NET
Language in a Nutshell introduces the important aspects of the language and explains the .NET
framework. An alphabetical reference covers the functions, statements, directives, objects, and object
members that make up the VB .NET language. To ease the transition, each language element
includes a "VB .NET/VB 6 Differences" section.
Finally, "do exist," the human and robot share common

classes of tasks: moving in a specific environment with obstacles, and different actions

coexistence is concerned, appropriate positioning systems combine design, sensor elements,

C++ is a powerful language that unifies high-level programming paradigms, such as object oriented
programming, with low-level efficiencies, such as the ability to directly manipulate memory. For these
reasons, C++ has been embraced as the language of choice among game developers.
Objectives: Explain how a small network of directly connected segments is created, configured, and verified. In this activity, you will demonstrate that you know how to design, configure, verify, and secure a very small network. Documentation and presentation are also vital parts of this Capstone Project.
Among funds, there are substantial differences in risk-return profiles,
investment horizons, asset allocation, eligible instruments, risk tolerances, and
Because each fund is different and has varying goals and objectives,
it is difficult to generalize about the investment strategies of SWFs as a class. For
example, an oil-exporting economy may initially establish a SWF for stabilization
The mission of the RAND Institute for Civil Justice is to improve private and public
decisionmaking on civil legal issues by supplying policymakers and the public with the results of
objective, empirically based, analytic research. The ICJ facilitates change in the civil justice system
by analyzing trends and outcomes, identifying and evaluating policy options, and bringing
together representatives of different interests to debate alternative solutions to policy problems.
Objective: Explain the purpose and operation of ACLs. Scenario: Each individual in the class will record five questions they would ask a candidate who is applying for a security clearance for a network assistant position within a small- to medium-sized business.
A constructor is a special method that used to initialize the properties of the object
A constructor is invoked when the object gets instantiated
Note to write a constructor:
The name of the constructor and the name of the class are the same
A constructor does not return value, not even void
A class can have multiple constructors (overloaded constructors)
