Hi all
Greetings from me, dadu
Can we create a socket port scanning with methods like this?:confused:


because so far, I make it just like this :

import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;
import javax.swing.*;


public class MySocket{
    private JFrame frame = new JFrame();
    private JLabel LabelIp,LabelFirs,LabelLast;
    private JTextField txtIp,txtFirsPort,txtLastPort;
    private JButton btnPort,btnExit;
    private JTextArea Scanning;
    static int ulang;
    public void buatTampilan(){
        LabelIp = new JLabel("IP : ");
        LabelIp.setSize(LabelIp.getPreferredSize());
        LabelIp.setLocation(20,20);

        txtIp = new JTextField(20);
        txtIp.setSize(txtIp.getPreferredSize());
        txtIp.setLocation(100,20);

        LabelFirs = new JLabel("firs port : ");
        LabelFirs.setSize(LabelFirs.getPreferredSize());
        LabelFirs.setLocation(20,60);

        txtFirsPort = new JTextField(20);
        txtFirsPort.setSize(txtFirsPort.getPreferredSize());
        txtFirsPort.setLocation(100,60);

        LabelLast = new JLabel("Last Port : ");
        LabelLast.setSize(LabelLast.getPreferredSize());
        LabelLast.setLocation(20,100);

        txtLastPort = new JTextField(20);
        txtLastPort.setSize(txtLastPort.getPreferredSize());
        txtLastPort.setLocation(100,100);

        btnPort = new JButton("Scan");
        btnPort.setSize(btnPort.getPreferredSize());
        btnPort.setLocation(20,140);
        btnPort.setMnemonic('S');

        btnExit = new JButton("Exit");
        btnExit.setSize(btnExit.getPreferredSize());
        btnExit.setLocation(100,140);
        btnExit.setMnemonic('K');

        Scanning = new JTextArea(20,25);
        Scanning.setLocation(20,180);

    }

    public void CreateGui(){

        frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE);
        frame.setLayout(new FlowLayout());
        frame.setTitle("Port Scanning");
        frame.getContentPane().add(LabelIp);
        frame.getContentPane().add(txtIp);
        frame.getContentPane().add(LabelFirs);
        frame.getContentPane().add(txtFirsPort);
        frame.getContentPane().add(LabelLast);
        frame.getContentPane().add(txtLastPort);
        frame.getContentPane().add(btnPort);
        frame.getContentPane().add(btnExit);
        frame.getContentPane().add(Scanning);
        frame.setSize(320,500);
        frame.setVisible(true);

        btnPort.addActionListener(new ActionListener(){
        private String varIp,varPortAwal,varPortAkhir,textlamabener;
        private int jumlahIp,jumlahPortAwal,jumlahPortAkhir;
        int po_a,po_b;
            public void actionPerformed(ActionEvent a){

                varIp = txtIp.getText();
                varPortAwal = txtFirsPort.getText();
                varPortAkhir = txtLastPort.getText();

                po_a = Integer.parseInt(varPortAwal);
                po_b = Integer.parseInt(varPortAkhir);

                jumlahIp = varIp.length();
                jumlahPortAwal = varPortAwal.length();
                jumlahPortAkhir = varPortAkhir.length();

                    if(jumlahIp > 0){
                        if(jumlahPortAwal > 0){
                            if(jumlahPortAkhir > 0){

                                for(ulang=po_a;ulang<=po_b;ulang++){
                                    mulai(varIp,ulang);
                                }
                                textlamabener = Scanning.getText();
                                Scanning.setText(textlamabener + "\n Scanning");

                            }else{
                                JOptionPane.showMessageDialog(null,"Last Port is empty");
                            }
                        }else{
                            JOptionPane.showMessageDialog(null,"Firs Port is empty");
                        }
                    }else{
                        JOptionPane.showMessageDialog(null,"Ip is empty");
                    }


            }

        });

        btnExit.addActionListener(new ActionListener(){

            public void actionPerformed(ActionEvent e){
                System.exit(1);
            }

        });
    }
    public void mulai(String IP,int ulang){
    String textLama,textLm;
    String strPort;
        try{

                textLama = Scanning.getText();
                strPort = Integer.toString(ulang);
                Scanning.setText(textLama + "Port . . .");

                Socket gw = new Socket(IP,ulang);
                textLm = Scanning.getText();
                Scanning.setText(textLm + strPort + " Connected \n");

        }catch(Exception aku){

            textLama = Scanning.getText();
            strPort = Integer.toString(ulang);
            Scanning.setText(textLama + strPort +" Not Connected \n");

        }

    }

    public static void main(String[] args){
        MySocket j = new MySocket();
        j.buatTampilan();
        j.CreateGui();

    }
}

if it can, I really hope anyone can teach me to make it. because I have already tried and find references but it's not success.

thank you

For god's sake, please stop begging and tell us specifically what isn't working. Until you do, it is unlikely anyone will help you since they have no idea how to help you.

Seems this thread is useless for me.
