in the following example, you can learn how you can check the status of the windws service, and you can analyze it to perform certain actions.

import java.util.*;
import java.sql.*;
import java.io.*;
import java.text.*;
public class doscmd 
 { 
    public static void main(String args[]) 
      { 
        try 
         { 
           Process p=Runtime.getRuntime().exec("sc query browser"); 

BufferedReader reader=new BufferedReader(new InputStreamReader(p.getInputStream())); 

           String line=reader.readLine();
           while(line!=null) 
            { 
              if(line.trim().startsWith("STATE"))

               {

                if (line.trim().substring(line.trim().indexOf(":")+1,line.trim().indexOf(":")+4).trim().equals("1"))
    System.out.println("Stopped");
else
    if (line.trim().substring(line.trim().indexOf(":")+1,line.trim().indexOf(":")+4).trim().equals("2"))
        System.out.println("Startting....");
    else
        if (line.trim().substring(line.trim().indexOf(":")+1,line.trim().indexOf(":")+4).trim().equals("3"))
            System.out.println("Stopping....");
        else
            if (line.trim().substring(line.trim().indexOf(":")+1,line.trim().indexOf(":")+4).trim().equals("4"))
                System.out.println("Running");

  }
   line=reader.readLine(); 
   } 

 } 

 catch(IOException e1) { } 



   } 
 }

At the very least, you should start the cmd.exe process with a command sc query service-nameand analyze the output to determine the status. Not really, but not enough Java API for Windows Service Manager, this would be a viable alternative.

EDIT. Javadoc java.lang.ProcessBuilder, . , redirectErrorStream, (stdout stderr), .
