A program is a set of instructions that when executed will perform
a specific task on a computer. Programs written in the JAVA
language take the for of either an Applet or an Application.
Applets run inside of a browser window whereas Applications
normally run stand alone on a specific computer.
A programmer creates Variables that will stand for certain things
in his or her program. These Variables will take on values during the
course of the program executing. The programmer supplies commands
in the program that symbolically manipulate or plays with the
This manipulation is in the form of inputting values, doing arithmetic,
making comparisons, or outputting results. The JAVA commands
used to perform these tasks plays with the Variables but in reality
the VALUES in the variables are what is really being played with.
So in essence, programmers must be able to envision ahead of time
how a problem is to be solved. Use Variables along with the JAVA
commands in some kind of a order that will accomplish the desired
task. REMEMBER that the Variables will take on Values once the
program starts to execute.
Using Variables and JAVA commands is very easy. The hard part
is writing down the commands in the right order to solve the
Being able to reason in an abstract manner is very important. You have
to be able to visualize the tasks involved in your head before you can
attempt to put then down on paper in the form of a program. Over the
years techniques have been developed to assist students in this task.
Projects are broken down into many small tasks ( instead of one
task ) so that they can be dealt with more effectively.
