Detect if Java application was run as a Windows admin

Question

I have a Java application. Is there anyway I can tell if the process was run with admin privileges, on Windows 7.

Answer 1

Below code worked out for me

Command prompt command

net user

Java code

public static  boolean isAdmin() {
        StringBuilder outputbuilder = new StringBuilder();
    try {
        ProcessBuilder builder = new ProcessBuilder(
                "cmd.exe","/c" ,"net user");
        builder.redirectErrorStream(true);
        Process p = builder.start();
        BufferedReader r = new BufferedReader(new InputStreamReader(p.getInputStream()));
        String line;
        while (true) {
            line = r.readLine();
            if (line == null) { break; }
            outputbuilder.append(line);
        }
    } catch (IOException e) {
        e.printStackTrace();
        return false;
    }
    System.out.println(outputbuilder.toString());
    return outputbuilder.toString().contains("Administrator");
}
