java 实现操作dos命令

java实现操作dos命令的两种方式

1.读取文件中的命令

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

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();             }     }       }

 

运行结果如下：

 

第二种方式，直接读取命令

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();  
        }  
    }  
}
