私はプロジェクトで働いており、評価システムを作成したいと考えています。5 番目の星を押すと、すべての星が赤くなり、4 番目の星を押すと、すべての星が赤くなります。1st スタート、2nd スター、3rd スターは赤色に変わります。どなたかアドバイス頂けたら幸いです。ありがとう!
これが私のコードです:
public class Rating {
private ArrayList<String> results = new ArrayList<String>();
private JLabel inputLabel1;
public static void main(String[] args) {
new Rating();
}
public Rating() {
JFrame f2 = new JFrame("Rating");
inputLabel1 = new JLabel("Rate: ");
Icon icon1 = new ImageIcon("star-icon.png");
Icon icon2 = new ImageIcon("star-3-icon.png");
JButton button1 = new JButton(icon1);
button1.setPreferredSize(new Dimension(35, 35));
button1.setBorder(BorderFactory.createEmptyBorder());
button1.setContentAreaFilled(false);
button1.setDisabledIcon(icon1);
button1.setPressedIcon(icon2);
button1.setSelectedIcon(icon2);
button1.setRolloverEnabled(true);
button1.setRolloverIcon(icon2);
button1.setRolloverSelectedIcon(icon2);
JButton button2 = new JButton(icon1);
button2.setPreferredSize(new Dimension(35, 35));
button2.setBorder(BorderFactory.createEmptyBorder());
button2.setContentAreaFilled(false);
button2.setDisabledIcon(icon1);
button2.setPressedIcon(icon2);
button2.setSelectedIcon(icon2);
button2.setRolloverEnabled(true);
button2.setRolloverIcon(icon2);
button2.setRolloverSelectedIcon(icon2);
JButton button3 = new JButton(icon1);
button3.setBorder(BorderFactory.createEmptyBorder());
button3.setContentAreaFilled(false);
button3.setDisabledIcon(icon1);
button3.setPressedIcon(icon2);
button3.setSelectedIcon(icon2);
button3.setPreferredSize(new Dimension(35, 35));
button3.setRolloverEnabled(true);
button3.setRolloverIcon(icon2);
button3.setRolloverSelectedIcon(icon2);
JButton button4 = new JButton(icon1);
button4.setPreferredSize(new Dimension(35, 35));
button4.setBorder(BorderFactory.createEmptyBorder());
button4.setContentAreaFilled(false);
button4.setDisabledIcon(icon1);
button4.setPressedIcon(icon2);
button4.setSelectedIcon(icon2);
button4.setRolloverEnabled(true);
button4.setRolloverIcon(icon2);
button4.setRolloverSelectedIcon(icon2);
JButton button5 = new JButton(icon1);
button5.setPreferredSize(new Dimension(35, 35));
button5.setBorder(BorderFactory.createEmptyBorder());
button5.setContentAreaFilled(false);
button5.setDisabledIcon(icon1);
button5.setPressedIcon(icon2);
button5.setSelectedIcon(icon2);
button5.setRolloverEnabled(true);
button5.setRolloverIcon(icon2);
button5.setRolloverSelectedIcon(icon2);
