Napisanie aplikacji Java

Question

Witam,

Czy ktoś byłby w stanie napisać mi taką aplikację w java ?

Aplikacja okienkowa, z której wczytujemy plik z dysku i liczy nam liczbę znaków i cyfr oraz liczbę spacji i enter-ów.

Proszę bardzo o pomoc.

Oferty proszę pisać w komentarzu lub na priv.

Z góry dziękuję.

Answer 1

To jest bardzo proste, napisz sobie sam taki program korzystając z dokumentacji/tutoriali...

Niestety, muszę taki program napisać na jutro, a już probowałem cos takiego robic.

Wyszło mi cos takiego ;/

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.Date;

public class Okno extends JFrame implements ActionListener
{
    JButton bWczytaj;
    JLabel lWyświetl;
    public Okno()
    {
        setSize(400,300);
        setTitle("Aplikacja na 3");
        setLayout(null);
        
        bWczytaj = new JButton("Wczytaj");
        bWczytaj.setBounds(150, 100, 100, 50);
        add(bWczytaj);
        bWczytaj.addActionListener(this);
        
        lWyświetl = new JLabel("Tekst:");
        lWyświetl.setBounds(50, 150, 250, 50);
        add(lWyświetl);
        
    }

    public static void main(String[] args)
    {
        Okno okienko = new Okno();
        okienko.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        okienko.setVisible(true);
        
             }

    public void actionPerformed(ActionEvent args)
    {
         try {
               // Uworzenie obiektu FileReader
               FileReader fileReader = new FileReader("test.txt");
               
               // Utworzenie obiektu bufferReader
               BufferedReader bufferReader = new BufferedReader(fileReader);
               
               String linia;
               
               while((linia = bufferReader.readLine()) != null) {
                System.out.println(linia);
                
               }
               fileReader.close();
              }
              catch (FileNotFoundException e) {
               e.printStackTrace();
              }
              catch (IOException e) {
               e.printStackTrace();
              }
         lWyświetl.setText(new linia());
    }

    
}

Tutaj masz przykład napisany w JaviaFX:

public class MainViewController {

    @FXML
    private Button btnOpenFile;
    @FXML
    private Button btnAcceptFile;
    @FXML
    private Label lblLine;
    @FXML
    private Label lblSign;
    @FXML
    private Label lblDigit;
    @FXML
    private Label lblCharacter;
    @FXML
    private Label lblSpace;
    @FXML
    private Label lblMsg;
    File file;

    @FXML
    void openFile(ActionEvent event) {
        FileChooser fileChooser = new FileChooser();
        fileChooser.setTitle("Wybierz plik");
        fileChooser.setInitialDirectory(new File(System.getProperty("user.home")));
        fileChooser.getExtensionFilters().addAll(new FileChooser.ExtensionFilter("TXT", "*.txt"),
                new FileChooser.ExtensionFilter("ALL", "*.*"));
        file = fileChooser.showOpenDialog(new Stage());
        if (file != null) {
            lblMsg.setText(file.getAbsolutePath());
        } else {
            lblMsg.setText("Niepoprawny plik");
        }
    }

    @FXML
    void acceptFile(ActionEvent event) {
        final String filePath = file.getAbsolutePath();
        long nrLine = -1;
        int nrSign, nrDigit, nrChar, nrSpace;
        String content = null;

        try {
            content = new String(Files.readAllBytes(Paths.get(filePath)));
            nrLine = Files.lines(Paths.get(filePath)).count();
        } catch (IOException e) {
            lblMsg.setText("Niepoprawny plik");
            e.printStackTrace();
        }

        // System.out.println(checkPattern(content, "\\n"));
        lblLine.setText(Long.toString(nrLine));

        nrSpace = checkPattern(content, " ");
        lblSpace.setText(Integer.toString(nrSpace));

        nrDigit = checkPattern(content, "\\d");
        lblDigit.setText(Integer.toString(nrDigit));

        nrChar = checkPattern(content, "[a-zA-Z]");
        lblCharacter.setText(Integer.toString(nrChar));

        nrSign = checkPattern(content, "\\w");
        lblSign.setText(Integer.toString(nrSign));

    }

    private int checkPattern(String content, String pattern) {
        Pattern p = Pattern.compile(pattern);
        Matcher m = p.matcher(content);
        int iterator = 0;
        while (m.find()) {
            iterator++;
        }
        return iterator;
    }
}
