Coloring specified character of String-CodePudding

I searched for this issue and I found the below codes, but these codes are for Java-Android. What are the similar codes that I can use with Java

The codes are:

ArrayList<Integer> positions = new ArrayList();
Pattern p = Pattern.compile("mp");  // insert your pattern here
Matcher m = p.matcher("Simple Text, bumping , jumping");
while (m.find()) {
    positions.add(m.start());
}

Spannable spanning = new SpannableString("Simple Text");        
spanning.setSpan(new ForegroundColorSpan(Color.BLUE),positions.get(i), positions.get(i) 1, 
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    
textview.setText(spanning);

Are you using Java Swing?

If yes, you can put "<html>YOUR TEXT</html>" with needly customizations for you design.

Put it inside an new JLabel("<html>YOUR..."); It is the principle of Java graphics design, and today we have the JavaFX that will replace these method of interface programming

Your soloution. You can change the colour of the label. add this to your jframe or jlabel as you have used in your project. Thank you

Label label = new Label("Your text");
//sets the colour of text
label.setForeground(Color.BLACK);
//sets the backround of text
label.setBackground(Color.BLUE);
