Introduction:
"Java is a programming language and computing platform first released by Sun Microsystems in 1995. It is the underlying technology that powers state-of-the-art programs including utilities, games, and business applications. Java runs on more than 850 million personal computers worldwide, and on billions of devices worldwide, including mobile and TV devices."
Follow the rules
A compiler goes a long way to help us create programs to create helpful results . However , it is still quite dumb . That is , you cannot just fill in your own words for describing what you want!
So , two things are important at this stage.
1. You need to follow a STRUCTURE the Java compiler will understand.
Java expect you to fill in code into parts called classes.
Each program will have a main class , which determines the way in which the rest of the classes will work together .
2.You have to use KEYWORDS which are the only words the Java compiler will understand.
Keywords instruct the compiler what to do. Eg 'print' tells the compiler to tell the computer to display something on the screen .
Installing required Software.
To start programming with Java you need two things . The Java Development Kit (JDK) is basically a set of tools to help you create your programs .The second program required is JCreator which provides the environment (Windows,buttons,menus) to create your program in.
