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”);

Given the code below, what will be the value returned from the method invocation shown? public static int mystery(int num1, int num2) {   if (num1 == 1 || num2 == 1) {        return 1;    } else {       return num2 + mystery(num1 / 3, num2 + 1);    }} int value = mystery(27, 7);

What will be the output from the regex below. items = [“0BagBueg”, “nponeav3”, “bBcdav”, “avave_aa”, “lakeB4vaB”]print items.grep(/\Bav\B/)  

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 Car {     private String make;     private double mileage;     /* 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.
