javac is the Java interpreter and it executes bytecode.

Write an equivalent lambda expression that implements the functional interface EQ 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 ClassThatDoesSomething { public static void main(String[] args) { ClassThatDoesSomething ctds = new ClassThatDoesSomething(); ctds.cmp(new EQ() { public boolean eq(char c1, char c2) { return c1 == c2; } }); } public void cmp(EQ test) { test.eq(‘t’, ‘T’); }}interface EQ { public boolean eq(char c1, char c2);} 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 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(“Don’t Press here!”);button.setOnMouseClicked( new EventHandler() { @Override       public void handle(MouseEvent e) {           System.out.println(“Boom!”);       }   });  

  ^~^  , (‘Y’) ) /   \/ Object’s    __QQ (\|||/) equals() (_)_”>                   /       

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

Given the code, is Test checked or unchecked? Is Tracker checked or unchecked?  Test : [Item1] Tracker : [Item2] class Test extends Exception {     public Test(String msg) {         super(msg);     } }  class Tracker extends RuntimeException {     public Tracker(String msg) {         super(msg);     } } 

What is the output of the following code?  String str = “GT”; int z = 24; if ((str + z).length() > 4) { System.out.println(“nice”); } else { if (z < str.length()) System.out.println("cool"); System.out.println("cheerio"); }

public class Coffee{   public Coffee () {         System.out.println(“COFFEE”);     } } public class Latte extends Coffee {   public Latte() {        System.out.println(“LATTE”);     } } public class VanillaLatte extends Coffee {   public Mocha() {   super();       System.out.println(“VANILLA”);   } } Given the class definitions above, what is printed to the console when the following lines of code are executed? Assume the code compiles and runs (i.e. ignore typos). Latte l = new Latte(); VanillaLatte v = new VanillaLatte();

Consider the code below. What is the output after it is run?  String s1 = “YELLOW”; String s2 = “JACKETS”; s2.toLowerCase(); s1 = s2; s2 = s1 + s2.charAt(1); System.out.println(s2); 

What is the output of the following code? int num1 = 20;int num2 = 100;if (num2 < num1)    if (num2 > 50)        System.out.println(“foo”);else     System.out.println(“bar”);
