Keep it simple, go into the code under jbInit() and rewrite it like this;
JButton2 jButton2 = new JButton();
jButton2.setBackground(Color.pink);
jButton2.setBounds(new Rectangle(100, 188, 85, 32));
jButton2.setFont(new java.awt.Font("Dialog", 1, 14));
jButton2.setText("Cats");
jButton2.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e) {
Cats();
}
});
JButton1 jButton2 = new JButton();
jButton1.setBackground(Color.green);
jButton1.setBounds(new Rectangle(100, 120, 85, 32));
jButton1.setFont(new java.awt.Font("Dialog", 1, 14));
jButton1.setText("Dogs");
jButton1.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e) {
Dogs();
}
});
