Java执行bat批处理文件，并关闭cmd窗口

package com.baobaotao.test;      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  E:\\run.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           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();           }       }   }
