Reopen an already running application(.exe) using java

I have a java program that opens up a .exe file. What i want to do is,

1)Run the .exe file when the java program is executed - Runs perfectly

2) When running the same code again, I want to reopen the previously executed exe.I dont want the .exe file to execute again.

EDIT: Is there a way to do the above? My only concern is the 2nd question. I have made the 1st question to work

On the request of Luffy. This is the code that i had used to get the list of running process and check whether a particular exe is running or not. Hope it helps for others.

 try 
    {
        String line;
        String pidInfo = "";
        Process proc = Runtime.getRuntime().exec("wmic.exe");
        BufferedReader input = new BufferedReader(new InputStreamReader(proc.getInputStream()));
        OutputStreamWriter oStream = new OutputStreamWriter(proc.getOutputStream());
        oStream .write("process where name='test.exe'");
        oStream .flush();
        oStream .close();
        while ((line = input.readLine()) != null) {
            pidInfo+=line;
        }
        input.close();

        if(pidInfo.contains("test.exe"))
        {
            System.out.println("exe already running");
        }
        else
        {
            System.out.println("exe not running");
            Process p = Runtime.getRuntime().exec(new String[] {"C:\\Program Files (x86)\\ToTestEXE\\test.exe"});
        }
    }
    catch (IOException e) 
    {
        e.printStackTrace();
    }
