Comment puis-je personnaliser la couleur du texte dans des segments spécifiques d'un JTextArea ?

import java.awt.*;

import javax.swing.text.*;

public class TextCustomization {

    public static void main(String[] args) {
        // Create a JTextPane for displaying the text
        JTextPane textPane = new JTextPane();

        // Create a SimpleAttributeSet to control text attributes
        SimpleAttributeSet blueAttributeSet = new SimpleAttributeSet();
        StyleConstants.setForeground(blueAttributeSet, Color.BLUE);

        SimpleAttributeSet greenAttributeSet = new SimpleAttributeSet();
        StyleConstants.setForeground(greenAttributeSet, Color.GREEN);

        SimpleAttributeSet redAttributeSet = new SimpleAttributeSet();
        StyleConstants.setForeground(redAttributeSet, Color.RED);

        SimpleAttributeSet orangeAttributeSet = new SimpleAttributeSet();
        StyleConstants.setForeground(orangeAttributeSet, Color.ORANGE);

        // Set the text and apply color attributes to specific segments
        String text = "LOAD R1, 1\nDEC R1\nSTORE M, R1\nADD R4, R1,8";
        textPane.setText(text);

        // Color specific words
        textPane.setParagraphAttributes(blueAttributeSet, true);
        textPane.setCaretPosition(0);
        textPane.setSelectedTextColor(Color.BLUE);
        textPane.setSelectionStart(0);
        textPane.setSelectionEnd(4);
        textPane.replaceSelection("LOAD");

        textPane.setParagraphAttributes(greenAttributeSet, true);
        textPane.setCaretPosition(5);
        textPane.setSelectedTextColor(Color.GREEN);
        textPane.setSelectionStart(5);
        textPane.setSelectionEnd(7);
        textPane.replaceSelection("R1,");

        textPane.setParagraphAttributes(redAttributeSet, true);
        textPane.setCaretPosition(9);
        textPane.setSelectedTextColor(Color.RED);
        textPane.setSelectionStart(9);
        textPane.setSelectionEnd(10);
        textPane.replaceSelection("M");

        textPane.setParagraphAttributes(orangeAttributeSet, true);
        textPane.setCaretPosition(12);
        textPane.setSelectedTextColor(Color.ORANGE);
        textPane.setSelectionStart(12);
        textPane.setSelectionEnd(13);
        textPane.replaceSelection("R1,");
    }
}
