Answer 1

import javax.swing.*;
import javax.swing.table.DefaultTableModel;
import java.awt.*;

public class Main {
    public static void main(String[] args) {
        JFrame tableFrame = new JFrame("Table");
        JPanel tablePanel = new JPanel();
        tablePanel.setLayout(new BorderLayout());
        DefaultTableModel defaultTableModel = new DefaultTableModel();
        defaultTableModel.addColumn("Integers");
        JTable table = new JTable(defaultTableModel);
        JScrollPane scrollPane = new JScrollPane(table);
        tablePanel.add(scrollPane, BorderLayout.CENTER);
        tableFrame.add(tablePanel);

        JFrame listFrame = new JFrame("List");
        JPanel listPanel = new JPanel();
        listPanel.setLayout(new BorderLayout());
        JList<String> list = new JList<>(new String[]{"1", "2", "3", "4"});
        JButton button = new JButton("To table");
        button.addActionListener(event -> {
            for (int i = 0; i < list.getModel().getSize(); i++) {
                DefaultTableModel model = (DefaultTableModel) table.getModel();
                model.addRow(new String[]{list.getModel().getElementAt(i)});
            }
        });
        listPanel.add(new JScrollPane(list), BorderLayout.CENTER);
        listPanel.add(button, BorderLayout.SOUTH);
        listFrame.add(listPanel);

        tableFrame.setSize(200, 250);
        tableFrame.setResizable(false);
        tableFrame.setVisible(true);
        tableFrame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

        listFrame.setSize(200, 250);
        listFrame.setResizable(false);
        listFrame.setVisible(true);
        listFrame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    }
}
