Even if that were not the case, Java as a language has significant advantages over other languages and other programming environments that make it suitable for just about any programming task. This section describes some of those advantages. Java Is Platform-Independent 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.<b><span style="color: blue;"><a href="https://youtu.be/IXkDSMAhdk0?list=PLoVO9Yha8Fi1BjDWHeKnhsMWNHt44ICrH" target="_blank">See More Videos About Java Programming:- </a></span></b> Java is platform-independent at both the source and the binary level. Platform-independence is a program’s capability of moving easily from one computer system to another. At the source level, Java’s primitive data types have consistent sizes across all development platforms. Java’s foundation class libraries make it easy to write code that can be moved from platform to platform without the need to rewrite it to work with that platform. Platform-independence doesn’t stop at the source level, however. Java binary files are also platform-independent and can run on multiple problems without the need to recompile the source. How does this work? Java binary files are actually in a form called bytecodes. Bytecodes are a set of instructions that looks a lot like some machine codes, but that is not specific to any one processor. Normally, when you compile a program written in C or in most other languages, the compiler translates your program into machine codes or processor instructions. Those instructions are specific to the processor your computer is running—so, for example, if you compile your code on a Pentium system, the resulting program will run only on other Pentium systems. If you want to use the same program on another system, you have to go back to your original source, get a compiler for that system, and recompile your code. Figure 1.2 shows the result of this system: multiple executable programs for multiple systems. Things are different when you write code in Java. The Java development environment has two parts: a Java compiler and a Java interpreter. The Java compiler takes your Java program and instead of generating machine codes from your source files, it generates bytecodes.</div> <div class="MsoNormal"> <o:p></o:p></div> <div class="MsoNormal"> <br /></div> <br /><div class="MsoNormal"> <br /></div> <br /></div>
