使用Java执行cmd命令

Question

I am trying to run 2 cmd commands in order to start tshark from cmd . Can you please help me understand why this code does not work?

    Process p = Runtime.getRuntime().exec("cmd.exe");

    BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));
    writer.write("cd C:/Program Files/Wireshark");
    writer.flush();

    writer.write("tshark.exe -i 1 -p -a duration:60 -w C:/Users/User/Desktop/AutomatedProtocolsPcapsCreator/CreatedPcaps/fileName.pcap");
    writer.flush();

Use ProcessBuilder . There are some gotchas around capturing console output, but otherwise I was very happy with this API.

new ProcessBuilder("tshark.exe", "-i",  "1", "-p", "-a", "duration:60", "-w",
  "C:/Users/User/Desktop/AutomatedProtocolsPcapsCreator/CreatedPcaps/fileName.pcap")
     .start()
