java判断是否Linux操作系统，判断OS操作系统类型工具类

 /**
     * 
     * @return 是否Linux操作系统
     * 
     */
    public static boolean isLinux() {
        return !System.getProperty("os.name").toLowerCase()
                .startsWith("windows");
    }

 上面代码的前提是该java程序只运行在Windows和Linux系统上面才是正确的。如果运行在Mac系统，那么就是有问题的。下面给出一个更加完整和全面的代码。具体用法参看里面的main函数
