java 执行bat批处理文件 并关闭cmd窗口

import java.io.IOException;

public class CmdMain {
 public static void main(String[] args){

  //执行批处理文件
  String strcmd="cmd /c start  D:\\antrelease.bat";
  Runtime rt = Runtime.getRuntime();
  Process ps = null;
  try {
     ps = rt.exec(strcmd);
  } catch (IOException e1) {
     e1.printStackTrace();
  }
  try {
   ps.waitFor();
  } catch (InterruptedException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  int i = ps.exitValue();
  if (i == 0) {
    System.out.println("执行完成.") ;
  } else {
    System.out.println("执行失败.") ;
  }
  ps.destroy();
  ps = null;

  //批处理执行完后，根据cmd.exe进程名称 kill掉cmd窗口(这个方法是好不容易才找到了，网上很多介绍的都无效)
  new CmdMain().killProcess();

 }

 public void killProcess(){
  Runtime rt = Runtime.getRuntime();
  Process p = null;
  try {
   rt.exec("cmd.exe /C start wmic process where name=‘cmd.exe‘ call terminate");
  } catch (IOException e) {
   e.printStackTrace();
  }
 }
}
