java實現操作dos命令的兩種方式

1.讀取檔案中的命令

package com;import java.io.InputStream;public class cmd {        public static void main(String[] args) {        String path = "D:\\cmd.bat";        Runtime run = Runtime.getRuntime();        try {            //run.exec("cmd /k shutdown -s -t 3600");            Process process = run.exec("cmd.exe /k start " + path);            InputStream in = process.getInputStream();            while (in.read() != -1) {                System.out.println(in.read());            }            in.close();            process.waitFor();        } catch (Exception e) {            e.printStackTrace();        }    }}

 

運行結果如下：

 

第二種方式，直接讀取命令

package com;import java.io.BufferedReader;  import java.io.InputStreamReader;   public class qumf {        public static void main(String[] args) {        try {                Runtime rt = Runtime.getRuntime();                Process pr = rt.exec("cmd /c ping www.baidu.com && dir");              //Process pr = rt.exec("D:\\xunlei\\project.aspx");                  BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream(), "GBK"));                String line = null;                while ((line = input.readLine()) != null) {                    System.out.println(line);                }                int exitVal = pr.waitFor();                System.out.println("Exited with error code " + exitVal);               } catch (Exception e) {               System.out.println(e.toString());               e.printStackTrace();          }      }  }
