Given only the JavaFX code below, which of the following most accurately describes the behavior of the button? (assume that the code is correctly included in a JavaFX GUI with correct imports but no additional methods called on the button object) Button button = new Button(“Danger!”);button.setOnAction(    new EventHandler() {        @Override        public void handle(ActionEvent e) {            System.out.println(“ALARM!”);        }    });  

Given the following code, what is the value of b? String s1 = “clownshoes”;String s2 = s1;s2.toUpperCase();boolean b = s2.equals(s1);

What is printed when the following code is run?   String a = “Stonks”; String b = new String(“Stonks”); String c = “Stonks”; System.out.println(a == b); System.out.println(c == b);

Given abstract parent class Tea.java, write a concrete child class that implements any necessary methods. You can pick any specific Tea type you want (e.g. black, matcha, green, chai, white, boba, etc). You do not have to provide method body statements for the method(s).  public abstract class Tea {   public abstract void brew(int time);   public void drink(int howMuch) {       // drink the tea   } }

Consider the code below. What is the output after it is run? String a = “apple”;String b = “banana”;b.replace(‘n’, ‘l’);a = b;b = a + a.length();System.out.println(b);

Given the code below, what will be the value returned from the method invocation shown? public static int mystery(int a, int b) {   if (a == 1 || b == 1) {        return 1;    } else {       return b + mystery(a / 2, b * 2);    }} int value = mystery(6, 6); 

Given only the JavaFX code below, which of the following most accurately describes the behavior of the button? (assume that the code is correctly included in a JavaFX GUI with correct imports but no additional methods called on the button object) Button button = new Button(“Press here!”); button.setOnAction(    new EventHandler() {         @Override        public void handle(ActionEvent e) {             System.out.println(“Boom!”);        }    } );
