java程序中调用Linux命令Windows命令

目前总结的方法：

调用Linux简单的命令行,设置文件夹权限755

String scriptDir = "/home/wenf";
String cmd = "chmod -R 755 "+scriptDir;
Runtime run = Runtime.getRuntime();
    try {
        run.exec(cmd);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

Windows环境中，调用DOS命令，创建目录c:\wenf0

Process process = Runtime.getRuntime().exec(new String[] { "cmd.exe","/C", "mkdir C:\\wenf0"});
