"text.append(" - " + words.get(i) + " (" + count.get(i) + " Mal)" + "\n" + " [ IDN: "+ identNum + " ]");"

Even tho I have ".append", the words in window2 are getting replaced if I repeat adding words from window1 into window2

Here's the full code of the programm if someone wants to test it:

package Files;

import java.text.SimpleDateFormat;

import java.util.*;

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

public class Shoppen {

public static void main(String[] args) {

//Window 1

//Windowsettings

JFrame frame1 = new JFrame("Selection");

frame1.setVisible(true);

frame1.setSize(500, 500);

frame1.setLocationRelativeTo(null);

frame1.setResizable(false);

//Ober e MenuBar

JMenuBar mb = new JMenuBar();

JMenu i1 = new JMenu("add article");

JMenu i2 = new JMenu("checkout");

mb.add(i1);

mb.add(i2);

frame1.setJMenuBar(mb);

frame1.s etDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

JLabel te2 = new JLabel("Welcome", JLabel.CENTER);

frame1.add(te2);

//Items

String[] is1 = {"Pizza", "Milk", "Breat", "Water", "Apple", "Rice", "Tomato", "Sausage", "Banana", "Yogurt"};

int[] identNum = {1, 2, 3, 4, 5, 6, 7, 8, 9 , 10};

double[] pl1 = {1.61, 0.75, 1.22, 0.42, 0.24, 1.52, 0.31, 1.47, 0.45, 1.86};

String[] is2 = {"print receipt"};

//Window 2

JFrame frame2 = new JFrame("shopping cart");

frame2.setVisible(true);

frame2.setSize(300, 1080);

frame2.setResizable(false);

frame2.setDefaultCloseOperation(JFrame.EXI T_ON_CLOSE);

Container con1 = frame2.getContentPane();

con1.setLayout(null);



//Date and Time

SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss");

String uhrzeit = sdf.format(new Date());

Date date = java.util.Calendar.getInstance().getTime();

SimpleDateFormat dateFormatter = new SimpleDateFormat("dd.MM.yyyy");

String dateString = dateFormatter.format(date);



//Feedback

JFrame frame3 = new JFrame("checkout");

for (int i = 0; i < is2.length; i++) {

JMenuItem mi3 = new JMenuItem(is2);

i2.add(mi3);

mi3.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

JOptionPane.showMessageDialog(null, "receipt is getting printed!");

frame3.setVisible(true);

}

});

}

for (int i = 0; i < is1.length; i++) {

JMenuItem mi1 = new JMenuItem(is1);

i1.add(mi1);

mi1.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

JOptionPane.showMessageDialog(null, "you added " + mi1.getText());

JTextArea text = new JTextArea();

text.setBounds(0, 100, 150, 675);

frame2.add(text);

//Wordcounter

Scanner fileInput = new Scanner(mi1.getText());

ArrayList<String> words = new ArrayList<String>();

ArrayList<Integer> count = new ArrayList<Integer>();

while(fileInput.hasNext()) {

String nextWord = fileInput.next();

if(words.contains(nextWord)) {

int index = words.indexOf(nextWord);

count.set(index, count.get(index) + 1);

} else {

words.add(nextWord);

count.add(1);

}

}

fileInput.close();;

for(int i = 0; i < words.size(); i++) {

text.setLineWrap(true);

text.append(" - " + words.get(i) + " (" + count.get(i) + " time(s))" + "\n" + " [ IDN: "+ identNum + " ]");

int rechnung1 = count.get(i);

String rechnung2 = words.get(i);

text.setEditable(true);

//Window 3

frame3.setVisible(false);

frame3.setSize(300, 1080);

frame3.setResizable(false);

frame3.setDefaultCloseOperation(JFrame.EXI T_ON_CLOSE);

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();

GraphicsDevice defaultScreen = ge.getDefaultScreenDevice();

Rectangle rect = defaultScreen.getDefaultConfiguration().getBounds();

int x = (int) rect.getMaxX() - frame3.getWidth();

int y = (int) rect.getMaxY() - frame3.getHeight();

frame3.setLocation(x, y);



Container con2 = frame3.getContentPane();

con2.setLayout(null);



JTextArea te1 = new JTextArea();

double summe = rechnung1 * pl1;

te1.setEditable(false);

te1.setText("| |" + "\n" +
