java 调用系统可执行程序

import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class RunDosCommand {
  public static void main(String[] args) throws IOException {
      String cmd = "ipconfig";
      Runtime run = Runtime.getRuntime();
      Process p = run.exec(cmd);
      BufferedInputStream in = new BufferedInputStream(p.getInputStream());
      BufferedReader br = new BufferedReader(new InputStreamReader(in));
      String s;
      while ((s = br.readLine()) != null)
          System.out.println(s);
  }
}
输出结果：
Windows IP Configuration
Ethernet adapter 區域連線:
Connection-specific DNS Suffix . : iacp.iac
IP Address. . . . . . . . . . . . : 10.162.54.45
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 10.162.54.1
Ethernet adapter 無線網路連線:
Media State . . . . . . . . . . . : Media disconnected
Ethernet adapter VirtualBox Host-Only Network:
Connection-specific DNS Suffix . :

输出的结果因电脑的不同，而不相同。
注：这样的情况下，是不会有Dos窗口弹出的。
public class RunDosCommand {
/**
* @param args
* @throws IOException 
*/
public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub
String path = System.getProperty("user.dir")+"/command/d.bat";
Runtime run = Runtime.getRuntime();
Process process = run.exec("cmd.exe /c start "+path);
   }
}
执行d.bat中的命令。
