Description: One of the most important characteristics of a computer is its ability to execute a series of instructions repeatedly. This cycle introduces the concept of loops, which allow the user great flexibility in controlling the number of times a specific task is to be repeated.

Description: If a certain condition is true, you direct the program to take one course of action. If the condition is false, you direct the program to do something else. This is one of the most fundamental concepts in computer programming. This decision-making can be done by means of the if construct. The if construct makes use of relational and logical operators for decision-making. The simplest form of if construct is as follows:

Description: The Internet helped catapult java to the forefront of programming, and java, in turn, has had a profound effect on the Internet. The reason for this is quite simple: Java expands the universe of objects that can move about freely in cyberspace. In a network, two very broad categories of objects are transmitted between the server and your personal computer: passive information and dynamic, active programs. For example, when you read your e-mail, you are viewing passive data. Even when you download a program, the program's code is still only passive data. Even when you download a second type of object can be transmitted to your computer: a dynamic, self-executing program. Such a program is and the server yet initiates active agent on the client computer. For example, the server to display properly the data that the server is sending might provide a program.

Description: Java is related to C++, which is a direct decendent of C. Much of the character of Java is inherited from these two languages. From C, java derives its syntax. Many of java's object-oriented features were influenced by C++. In fact, several of Java's defining characteristics come from of are responses to its predecessors. Moreover, the creation of java was deeply rooted in the process of refinement and adaptation that has been occurring in computer programming languages for the past three decades. For these reasons, this section reviews the sequence of events and forces that led up to java. As you will see, each innovation in languages design was driven by the need to solve a fundamental problem that the preceding languages could not solve. Java is no exception.
