Is there a way to keep a test.Bat file open and run the rest of the code?

Question

I have this code below - where the batch file is executed but the program wont execute the rest of the code rather it stay in the batch file itself. What I want to achieve is to have this BATCH file running while the rest of the code executes.

public class CmdJava {
    public static void main(String[] args) throws IOException {
        Process p = Runtime.getRuntime().exec("cmd /c call README.bat");
        
        String s;
        System.out.println(p.getOutputStream());
        BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
        while ((s = stdInput.readLine()) != null) {
            System.out.println(s);
//code reaches and stops at this line as the batch file need to be forcefully closed
        }
        System.out.print("Need to reach this code");
    }
}

Any help is greatly appreciated
