Why is the && operator not working in the if statement within (ActionEvent e) in this Java Program?

Hi. I am creating a Java program intended for displaying each of the forms of the Polish adjective “szczęśliwy” in a dialog box using JOptionPane. The problem is that && operator is not working as expected in (ActionEvent e). For instance, I have entered the following code

if (e.getSource() == radioButton[0] && (e.getSource() ==
radioButton1) && (e.getSource() == radioButton[9])) {
JOptionPane.showMessageDialog(null, “szczęśliwy”);

in order to display a JOptionPane message with the form “szczęśliwy”, which is the singular nominative animate masculine form of the Polish adjective, under the circumstances that the three corresponding JRadioButtons are checked when running the program. The corresponding Polish words are “liczba pojedyncza”(singular), “mianownik”(nominative) and “rodzaj męskoosobowy”(animate masculine). However, when I run the program and check the three corresponding JRadioButtons, no dialog box will appear, just like in the first image.

When I run the program and check only one JRadioButton listed below the first instance, a dialog box with the corresponding form of the Polish adjective will appear. All the other conditional statements have been created without the && operator and will work just fine, just like in the second image.

I wonder why the && operator is not working in this particular program. I would appreciate it if you could provide any solution to this problem. Thank you!

For reference purpose, the following image is the declension table for all the forms of the Polish adjective “szczęśliwy”.
