java调用exe的几种方法

　Runtime rt = Runtime.getRuntime();

try

{
        java.awt.Desktop.getDesktop().open(new File("E:\\XML2XLS\\circlegrid.exe"));

　//rt.exec("E:\\XML2XLS\\circlegrid.exe"); 
      //rt.exec(new  String[]{"cmd","/c","E:\\XML2XLS\\circlegrid.exe"});
      //rt.exec("\"E:\\XML2XLS\\circlegrid.exe\"");
     //rt.exec("cmd /c E:\\XML2XLS\\circlegrid.exe \f");  // \f前面有没有空格一样，去掉\f也没有影响,cmd
    }

catch (IOException e)
    {  
       e.printStackTrace();
    }
