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);  }}
