Java Learning Made Easy

that make it suitable for just about

any programming task. Some of them

are listed as follows:

o Applets

Applets appear in a Web page much in the

same way as images do, but unlike images,

applets are dynamic and interactive.

Applets can be used to create animations,

figures, or areas that can respond to input

from the reader, games, or other

interactive effects on the same Web pages

among the text and graphics. Java enabled

browsers can successfully run applets and

thus give a truly rich experience at the user

end.

o Platform Independence

Platform independence is one of the most significant advantages that Java has over other programming

languages, particularly for systems that need to work on many different platforms. Java is platform-independent at both the source and the binary level. Platformindependence is a program's capability of moving easily from one computer system to another. Java binary files called byte-codes are also platform-independent and can run on multiple platforms without the need to recompile the source. Byte-codes are a set of instructions that look a lot like machine code, but are not specific to any one processor. Because of them, compilation happens just once; interpretation occurs each time the program is executed. Java byte-codes help make "write once, run anywhere" possible.

o Simplicity

In addition to its portability and objectorientation, one of Java's initial design goals was to be small and simple, and

therefore easier to write, easier to compile,

easier to debug, and, best of all, easy to

learn. Keeping the language small also

makes it more robust because there are

fewer chances for programmers to make

difficult-to-find mistakes. Despite its size

and simple design, however, Java still has a

great deal of power and flexibility.

o Better Cousin of C, C++

Java is modeled after C and C++, and much of the syntax and object-oriented structure is borrowed from the latter. If you are familiar with C++, learning Java will be particularly easy for you, because you have most of the foundation already. Although Java looks similar to C and C++, most of the more complex parts of those languages have been excluded from Java, making the language simpler without sacrificing much of its power. There are no pointers in Java, nor is there pointer arithmetic. Strings and arrays are real objects in Java. Memory management is automatic. To an experienced programmer, these omissions may be difficult to get used to, but to beginners or programmers who have worked in other languages; they make the Java language far easier to learn.
