Java简单实现调用命令行并获取执行结果示例

本文实例讲述了java简单实现调用命令行并获取执行结果。分享给大家供大家参考，具体如下：

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);
  }
}

运行结果：

希望本文所述对大家java程序设计有所帮助。
