通过Java执行cmd时如何捕获输入流？

Question

I have return a small java code to execute the SC command on Remote Server and I am using LSRunas to give the admin credentials.

   String[] command = new String [3];
   command[0] = 'cmd';
   command[1] = "/c";
   command[2] = "lsrunas /user:username /password:password /domain:domain /command:"sc \\servername queryex"  /runpath:c\\"


  ProcessBulder buider = new ProcessBuilder(command);
  Process p = buider.start();

   BufferedReader reader = new  BufferedReader(new(InputStreamReader(p.getInputStrem()));
   String line = reader.readLine();
    while(line != null) {
         System.out.println(line);
         line = reader.readLine(); 

    }

The program works fine and it execute the SC command with provided credentials on remote server, but the problem is that it opens a new cmd windows to print the result (The common scenario while using RUNAS), But i want to capture the result and read it in my java program. Is there is any way i can capture the result from newly opened cmd window.

Answer 1

String line = reader.readLine();
while(line != null) {
     System.out.println(line);
}

This will just keep printing out the same line. Try:

String line;
while ((line = reader.readLine()) != null)
{
    System.out.println(line);
}
