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 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!”);        }    } );

Write an equivalent lambda expression that implements the functional interface LT that could be used to replace the anonymous inner class given below. An example inner anonymous class implementation is given below. The body of the implementation must match the implementation given. Note: you only need to write the lambda expression NOT the entire block of code below. public class IsItSummerYet { public static void main(String[] args) { IsItSummerYet summerYet = new IsItSummerYet(); summerYet.check(new LT() { public boolean lt(float f1, float f2) { return f1 < f2; } }); } public void check(LT iface) { iface.lt(1.331f, 3.1415f); }}interface LT { public boolean lt(float f1, float f2);} Make sure to select the 'Preformatted' style from the dropdown so your code is formatted clearly. DO NOT USE THE TAB KEY WHEN WRITING CODE AS YOU MAY ACCIDENTALLY SUBMIT YOUR EXAM. USE THE SPACE BAR INSTEAD.

Given abstract parent class Holiday.java, write a concrete child class that implements any necessary methods. You can pick any specific Holiday type you want (e.g. Christmas, Halloween, Thanksgiving, etc). You do not have to provide method body statements for the method(s).  public abstract class Holiday{     public abstract void celebrate(String[] items);     public String decorate() {         // do holiday stuff     } } 

You have compiled a file named Test.java. What command do you use to run the program in the terminal?

Given the class below, correctly override Object’s equals method in this class, ensuring that it compares the full state of the object (i.e. the values of all data fields).Include the method header, curly braces, and implementation in your response. public class Tacos {     private boolean hardShell;     private String meat;     /* assume a valid constructor exists */     /* YOUR equals METHOD HERE */ } Make sure to select the ‘Preformatted’ style from the dropdown so your code is formatted clearly. DO NOT USE THE TAB KEY WHEN WRITING CODE AS YOU MAY ACCIDENTALLY SUBMIT YOUR EXAM. USE THE SPACE BAR INSTEAD.

Given the code, is TreasureNotFound a checked or unchecked exception?
