The following example shows you how to set the property of the JTextArea so that it cannot be edited or modified. To make the JTextArea not editable call the setEditable() method and pass a false value as the parameter.

package org.kodejava.swing;

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

public class TextAreaNotEditable extends JPanel {
    public TextAreaNotEditable() {
        initializeUI();
    }

    public static void showFrame() {
        JPanel panel = new TextAreaNotEditable();
        panel.setOpaque(true);

        JFrame frame = new JFrame("JTextArea Demo");
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        frame.setContentPane(panel);
        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(TextAreaNotEditable::showFrame);
    }

    private void initializeUI() {
        this.setLayout(new BorderLayout());
        this.setPreferredSize(new Dimension(500, 200));

        JTextArea textArea = new JTextArea(5, 50);
        textArea.setText("The quick brown fox jumps over the lazy dog.");

        // By default, the JTextArea is editable, calling
        // setEditable(false) produce uneditable JTextArea.
        textArea.setEditable(false);
        JScrollPane scrollPane = new JScrollPane(textArea);

        this.add(scrollPane, BorderLayout.CENTER);
    }
}

The output of the code snippet is:
