     public class javaExample
{
   public static void main(String []args)
    {
    System.out.println("A java program example!");
    }
}

在C:\Document and Settings\Administrator>输入javac javaExample.java
结果为:
error: cannot read:javaExample.java

在C:\Document and Settings\Administrator>输入javac
结果为:
Usage:javac <options><source files>
where possible options include:
-g
-g:none
-nowarn

环境变量中用户变量设置为C:\Program Files\Java\j2re1.4.2_13\bin;C:\Program Files\Microsoft Visual Studio\Common\Tools\WinNT;C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin;C:\Program Files\Microsoft Visual Studio\Common\Tools;C:\Program Files\Microsoft Visual Studio\VC98\bin;D:\影视风暴\Codec;D:\影视风暴

系统按装了java 2 Runtime Environment,SE v1.4.2_13和java 2SDK,SE v1.4.2_13
[font color=#00FF00]     [font color=#FF0000]您后来给我的解条是:您可以将该文件保存到c盘根目录下，然后在上面的命令提示符后面输入cd\进入到c盘根目录，然后再执行javac javaExample.java。[/font]    [/font]

    [font color=#0000FF] 后来我按您的方法试了一下,现在又出现了下面的问题,请帮我处理一下哈[/font]

请把系统变量中的Path设置为C:\Program Files\Java\j2re1.4.2_13\bin;后边跟配置之前原来的内容

把系统变量中的ClassPath设置为C:\Program Files\Java\j2re1.4.2_13\lib\dt.jar;.;C:\Program Files\Java\j2re1.4.2_13\lib\tools.jar

然后把你编写的Java程序保存到硬盘，如c:\zzk文件夹中，进入命令行输入如下命令
cd c:\zzk回车结果如下
c:\zzk>
输入如下命令
javac javaExample.java回车即可
如果没用错误，则再输入
java javaExample回车即可运行。
