Button button1 = new Button("Button 1");
Button button2 = new Button("Button 2");
Button button3 = new Button("Button 3");

EventHandler<ActionEvent> eventHandler = event -> {
    // 在这里编写更改按钮文本的代码
};

button1.setOnAction(eventHandler);
button2.setOnAction(eventHandler);
button3.setOnAction(eventHandler);

button1.setText("New Text 1");
button2.setText("New Text 2");
button3.setText("New Text 3");
