Although Example.java is quite short, it includes several key features that are common to all Java programs. Let’s closely examine each part of the program. The program begins with the following lines: /* This is a simple Java program. Call this file “Example.java”. */ This is a comment. Like most other programming languages, Java lets … Read more
To compile the Example program, execute the compiler, javac, specifying the name of the source file on the command line, as shown here: C:\>javac Example.java The javac compiler creates a file called Example.class that contains the bytecode version of the program. As discussed earlier, the Java bytecode is the intermediate representation of your program that … Read more
For most computer languages, the name of the file that holds the source code to a program is immaterial. However, this is not the case with Java. The first thing that you must learn about Java is that the name you give to a source file is very important. For this example, the name of … Read more
