    Default Multiple colors for a textfield

    Hello,

    I have a question about JTextArea colors. When i set the color to blue and then write something on the JTextArea (JTextArea.append) and then set it back to black everything will be black. How can i solve that? Like in Notepad++ or Eclipse when you write keywords in a JTextArea (where you write your code) only some words change color.

    This is my code:
    // All the imports
     
    public class whatever extends JFrame {
     
    JTextArea a = new JTextArea();
     
    public whatever() {
     
    super("Title");
     
    add(a);
     
    a.setForeground(Color.RED);
    a.append("Hello there");
    a.setForeground(Color.BLACK);
     
    }
     
    }
     
    public static void main(String[] args) {
     
    whatever object = new whatever();
    object.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    object.setSize(400, 500);
    object.setVisible(true);
     
    }

    You cant. The JTextField does not support multiple colors at once.
    You can either subclass the JTextField and overwrite the paintComponent method or you use a different component, for example the JTextPane.

    Read the API doc for the class you are working with and see what methods use a color. Then experiment with those methods to see any of them will do what you want.
    If you don't understand my answer, don't ignore it, ask a question.

    Did you read the API doc for that class?
