回答1:

With what component do you display your text? If it is JTextArea, then it is not possible. You need a component that allows different styles. For example a StyledDocument in a JTextPane. For more information see How to Use Editor Panes and Text Panes

You can try the next:

public static void main(String[] args) {

    final JFrame frame = new JFrame("Selected Color Example");
    frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

    final JTextArea area = new JTextArea("Text for test...", 5, 10);
    frame.add(area, BorderLayout.CENTER);

    JButton button = new JButton("Select Color");
    button.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            Color color = JColorChooser.showDialog(frame, "Colors",
                    Color.BLUE);
            area.selectAll();
            // area.setSelectedTextColor(color); // color of selected text
            area.setSelectionColor(color); // background of selected text
            area.requestFocusInWindow();
        }
    });
    frame.add(button, BorderLayout.PAGE_END);

    frame.pack();
    frame.setVisible(true);

}
