Multiple ActionListeners in one class

I'd like to have multiple ActionListener's in my class. I'm making a simple game for a project that has 3 different levels, and a certain amount of buttons in each level.

After each level a new element or component is added. My first level has 25 buttons that when one is pushed they'll emit a random outcome which adds to your score. All these buttons do the same thing so I decided to use an ActionListener instead of having to write out 10 if statements per button. Problem being I want to do that with my second level but the class already has a defined action performed.

Is there any possible way to have more than one ActionListener in the same class?

Here is my ActionPerformed method:

    public void actionPerformed(ActionEvent e) {
     JButton source = (JButton)e.getSource();

        Random RG = new Random();
        level_1_random_block = (RG.nextInt(6));

        frame2.setVisible(false);
        if (level_1_random_block == 0){
            source.setIcon(new ImageIcon("C:\\Users\\Liam\\Desktop\\BOMB GAME\\oreDiamond.png"));
            score += 100;
            initialize_score();
        }
        if (level_1_random_block == 1){
            source.setIcon(new ImageIcon("C:\\Users\\Liam\\Desktop\\BOMB GAME\\oreGold.png"));
            score += 25;
            initialize_score();
        }
        if (level_1_random_block == 2){
            source.setIcon(new ImageIcon("C:\\Users\\Liam\\Desktop\\BOMB GAME\\oreGold.png"));
            score += 25;
            initialize_score();
        }
        if (level_1_random_block == 3){
            source.setIcon(new ImageIcon("C:\\Users\\Liam\\Desktop\\BOMB GAME\\oreIron.png"));
            score += 5;
            initialize_score();
        }
        if (level_1_random_block == 4){
            source.setIcon(new ImageIcon("C:\\Users\\Liam\\Desktop\\BOMB GAME\\oreIron.png"));
            score += 5;
            initialize_score();
        }
        if (level_1_random_block == 5){
            source.setIcon(new ImageIcon("C:\\Users\\Liam\\Desktop\\BOMB GAME\\creeper.png"));
            score -= 30;
            initialize_score();

            try {
                Clip clip = AudioSystem.getClip();
                clip.open(AudioSystem.getAudioInputStream(new File("C:\\Users\\Liam\\Desktop\\BOMB GAME\\creeper_sound.wav")));
                clip.start();
            }
            catch (Exception exc){

            }

        }
        if (level_1_random_block == 6){
            source.setIcon(new ImageIcon("C:\\Users\\Liam\\Desktop\\BOMB GAME\\creeper.png"));
            score -= 30;
            initialize_score();
        }

        source.removeActionListener((ActionListener) this);
        level_1_move_on = true;
        continue_game();

}
public void EventHandler(int level_1_random_block) {
   this.level_1_random_block = level_1_random_block;    
}

You can do an Inner Class:

button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e){ */Code goes here*/ } }) (save the actionListener in a variable and set it for many buttons)

Do this multiple times for different buttons and you have multipleActionListeners.

You can also set action commands. button.setActionCommad("lvl1");

In your actionPerformed(ActionEvent e) you can check with if: if(e.getActionCommand.equals("lvl1")) { /*code*/ }
