Instead of terminating with System.exit(whateverValue), why not throw an unchecked exception? In normal use it will drift all the way out to the JVM’s last-ditch catcher and shut your script down (unless you decide to catch it somewhere along the way, which might be useful someday). I...
这样,低版本的JVM无法解释执行这个.class文件,会抛出Couldnotfindthemainclass.programwillexit不支持的Class版本错误。 解决方法: 1. 弄清楚该程序是在哪个JDK版本下开发的 2. 在myEclipse 菜单->Windows->Proferences->java-> Installs Jres重新设置JDK路径,改为开发程序时的JDK版本(我做到这一步就可以了!我的e...
用的jdk1.6.0_45,也有说java环境变量配置错误,然后我又重新检查了一遍JAVA_HOME、CLASSPATH、PATH,发现环境变量也没有配置错误,实在郁闷,检查了半天,最后终于找到了解决办法,原来是我之前将这个项目的Builders中的Java Builder选项去除了,需要勾选上,然后clean下项目,重新运行...
Sometimes it is useful to terminate program immidiately, and the easiest way to do so in Java is via System.exit(0).However, it is rather poor programming practice and on Java courses I took, we were heavily discouraged to use it, as it terminates the whole currently running JVM and th...

1.首先，打开配置环境变量界面，如下操作：我的电脑---属性---高级---环境变量 2.系统变量（S）中配置如下：2.1,新建系统变量：变量名：JAVA_HOME 变量值：C:\Program Files\Java\jdk1.5.0_17（该目录为JDK安装的目录）2.2,编辑CLASSPATH，如果没有该变量则新建，变量名：CLASSPATH 变量值：...

1) EXIT如果出现在循环中,退出的是整个循环操作,.程序会从循环结束处开始继续执行,其作用相当于Java与C++中的break。 2)EXIT如果出现在循环之外,退出的是当前执行的程序块(processing block),例如一个FORM,METHOD,或EVENT,其作用与RETURN类似。 RETURN.
不能找到主程序,将要退出.环境
