42 <title>About Java</title>
43 <para>
44 Java is different from most of the packages in LFS and BLFS. It
45 is a programming language that works with files of bytecode to obtain
46 instructions and executes them in a Java Virtual Machine (JVM). An
47 introductory java program looks like:
48 </para>
49
50<screen><literal>public class HelloWorld
51{
52 public static void main(String[] args)
53 {
54 System.out.println("Hello, World");
55 }
56}</literal></screen>
57
58 <para>
59 This program is saved as <filename>HelloWorld.java</filename>. The
60 file name, <emphasis>HelloWorld</emphasis>, must match the class name.
61 It is then converted into byte code with
62 <command>javac HelloWorld.java</command>. The output file is
63 <filename>HelloWorld.class</filename>. The program is executed with
64 <command>java HelloWorld</command>. This creates a JVM and runs the
65 code. The 'class' extension must not be specified.
66 </para>
67
68 <para>
69 Several class files can be combined into one file with the
70 <command>jar</command> command. This is similar to the standard
71 <command>tar</command> command. For instance, the command
72 <command>jar cf myjar.jar *.class</command> will combine all class files
73 in a directory into one jar file. These act as library files.
74 </para>
75
76 <para>
77 The JVM can search for and use classes in jar files automatically.
78 It uses the <envar>CLASSPATH</envar> environment variable to search for
79 jar files. This is a standard list of colon-separated directory names
80 similar to the <envar>PATH</envar> environment variable.
81 </para>

87
88 <para>
89 Creating a JVM from source requires a set of circular dependencies.
90 The first thing that's needed is a set of programs called a Java
91 Development Kit (JDK). This set of programs includes
92 <command>java</command>, <command>javac</command>,
93 <command>jar</command>, and several others. It also includes several
94 base <emphasis>jar</emphasis> files.
95 </para>
96
97 <para>
98 To start, we set up a binary installation of the JDK created
99 by the BLFS editors. It is installed in the <filename>/opt</filename>
100 directory to allow for multiple installations, including a source based
101 version.
