Java简单实现调用命令行并获取执行结果示例

import java.io.bufferedreader;

import java.io.inputstreamreader;

public class command {

   public static void execmd(string commandstr) {

     bufferedreader br = null ;

     try {

       process p = runtime.getruntime().exec(commandstr);

       br = new bufferedreader( new inputstreamreader(p.getinputstream()));

       string line = null ;

       stringbuilder sb = new stringbuilder();

       while ((line = br.readline()) != null ) {

         sb.append(line + "\n" );

       }

       system.out.println(sb.tostring());

     } catch (exception e) {

       e.printstacktrace();

     }

     finally

     {

       if (br != null )

       {

         try {

           br.close();

         } catch (exception e) {

           e.printstacktrace();

         }

       }

     }

   }

   public static void main(string[] args) {

     string commandstr = "ping www.baidu.com" ;

     //string commandstr = "ipconfig";

     command.execmd(commandstr);

   }

}
