blocks|key|4291200|text|基本的想法(给你一些可以搜索的东西)是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4291201|4291202|将已编译的.class文件捆绑到一个‘jar’中。|unordered-list-item|4291203|将一个清单添加到jar中，指定要运行的主类。|4291204|4291205|当你运行一个“干净的构建”时，你可能会发现你的IDE已经创建了这个。Netbeans将其放入“dist”文件夹中。|4291206|现代JRE允许你通过双击jar来运行它，等等。|4291207|您还可以更进一步，使用诸如JSmooth之类的工具将jar包装在本地可执行文件中。|4291208|entityMap^0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|R|8|@]|9|@]|A|$]]|$1|C|3|D|5|E|7|S|8|@]|9|@]|A|$]]|$1|F|3|G|5|E|7|T|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|U|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|V|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|W|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|X|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|P|$]]

The basic idea (to give you some things to search for) is:

<ul>
<li>Bundle your compiled .class files into a 'jar'.</li>
<li>Add a manifest to your jar specifying a main class to run.</li>
</ul>

You might find your IDE already creates this when you run a 'clean build'. Netbeans puts this into a 'dist' folder.

Modern JREs will allow you to run the jar by double clicking it etc.

You can also go a bit further by wrapping the jar in a native executable using a tool such as JSmooth.

Or if you going to to serious stuff, opt for a build script like Ant or Maven. 
Here's an example of an Ant build.xml script:

<pre><code>&lt;project name="jar with libs" default="compile and build" basedir="."&gt;
 &lt;!-- this is used at compile time --&gt;
 &lt;path id="example-classpath"&gt;
 &lt;pathelement location="${root-dir}" /&gt;
 &lt;fileset dir="D:/LIC/xalan-j_2_7_1" includes="*.jar" /&gt;
 &lt;/path&gt;

 &lt;target name="compile and build"&gt;
 &lt;!-- deletes previously created jar --&gt;
 &lt;delete file="test.jar" /&gt;

 &lt;!-- compile your code and drop .class into "bin" directory --&gt;
 &lt;javac srcdir="${basedir}" destdir="bin" debug="true" deprecation="on"&gt;
 &lt;!-- this is telling the compiler where are the dependencies --&gt;
 &lt;classpath refid="example-classpath" /&gt;
 &lt;/javac&gt;

 &lt;!-- copy the JARs that you need to "bin" directory --&gt;
 &lt;copy todir="bin"&gt;
 &lt;fileset dir="D:/LIC/xalan-j_2_7_1" includes="*.jar" /&gt;
 &lt;/copy&gt;

 &lt;!-- creates your jar with the contents inside "bin" (now with your .class and .jar dependencies) --&gt;
 &lt;jar destfile="test.jar" basedir="bin" duplicate="preserve"&gt;
 &lt;manifest&gt;
 &lt;!-- Who is building this jar? --&gt;
 &lt;attribute name="Built-By" value="${user.name}" /&gt;
 &lt;!-- Information about the program itself --&gt;
 &lt;attribute name="Implementation-Vendor" value="ACME inc." /&gt;
 &lt;attribute name="Implementation-Title" value="GreatProduct" /&gt;
 &lt;attribute name="Implementation-Version" value="1.0.0beta2" /&gt;
 &lt;!-- this tells which class should run when executing your jar --&gt;
 &lt;attribute name="Main-class" value="ApplyXPath" /&gt;
 &lt;/manifest&gt;
 &lt;/jar&gt;
 &lt;/target&gt;
&lt;/project&gt;

I coded up 4 .java files. The thing is that I can only execute my .java files from my IDE, how do I execute the .class files like an application? I study at uni, and I was told that Java is platform independent. Any tutorial/book recommendations would be highly appreciated. 

Thanks

我编码了4个.java文件。问题是，我只能从我的集成开发环境中执行我的.java文件，如何像执行应用程序一样执行.class文件？我在uni学习，我被告知Java是独立于平台的。任何教程/书籍推荐都将受到高度赞赏。谢谢
