Java tool/method to force-kill a child process

Question

I am looking for a Java tool/package/library that will allow me to force-kill a child process.

This tool/package/library must work on Windows platform (mandatory).

Answer 1

For windows using jna 3.5.1

try {
        Process p = Runtime.getRuntime.exec("notepad");

        Field f = p.getClass().getDeclaredField("handle");
        f.setAccessible(true);              
        long handLong = f.getLong(p);

            Kernel32 kernel = Kernel32.INSTANCE;

        WinNT.HANDLE handle = new WinNT.HANDLE();

        handle.setPointer(Pointer.createConstant(handLong));

        int pid = kernel.GetProcessId(handle);

        System.out.print(pid);
    } catch (Throwable e) {
}
