I want to run command

ipmsg.exe /MSG 192.168.0.8 "TEXT MESSAGE"

by a java program. Can anybody help me?

I am trying the following lines. But it is not working..

Runtime run_t = Runtime.getRuntime();

Process notify = run_t.exec("cmd /c ipmsg.exe /MSG 192.168.0.8 Hello");

PS:- My computer is connected to the computer with ip address 192.168.0.8 with LAN.

ProcessBuilder外部プロセスの操作を改善するには、 を使用します。また、コマンド名とは別に、引数を常に別の文字列として渡します。

次のように、標準出力またはエラー出力をキャプチャするには、2 つのスレッドが必要です。

package demo;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;


public class ExecDemo {

    public static void main(String[] args) throws Exception {

        final Process p = Runtime.getRuntime().exec("nslookup google.com");
        Thread stdout = new Thread() {
            public void run() {
                BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
                String line = null;
                try {
                    while ((line = br.readLine())!=null) {
                        System.out.println(line);
                    }
                    br.close();
                } catch (IOException ioe) {
                    ioe.printStackTrace();
                }
            }
        };
        Thread stderr = new Thread() {
            public void run() {
                BufferedReader br = new BufferedReader(new InputStreamReader(p.getErrorStream()));
                String line = null;
                try {
                    while ((line = br.readLine())!=null) {
                        System.out.println(line);
                    }
                    br.close();
                } catch (IOException ioe) {
                    ioe.printStackTrace();
                }

            }
        };
        //
        stdout.start();
        stderr.start();
        //
        stdout.join();
        stderr.join();
        //
        p.waitFor();
    }

}
