Question

关注Getting started - （Windows 7，控制台：C：...＆gt;，。jar＆amp; .javauto在同一文件夹中）

java -jar javauto.jar              => OK, help is displayed 
javauto hello.javauto              => command not recognised                   
javauto.jar hello.javauto          => NO result

所以我试过这个

java -jar javauto.jar -v hello.javauto

给出此例外（注意：c：...＆gt; javac =＆gt;帮助显示正常）

Answer 1

试试这个：

1）使用此命令编译它：

java -jar javauto.jar  hello.javauto

2）现在您已经编译了程序，将会有一个名为 hello.jar 的文件。执行：

java -jar hello.jar

Javauto编译失败（入门）
