Given abstract parent class VideoGame.java, write a concrete child class that implements any necessary methods. You can pick any specific Video Game type you want (e.g. action, role playing, puzzle, strategy  etc). You do not have to provide method body statements for the method(s). public abstract class VideoGame {    public abstract void launchGame();    public int buyGame(int cost) {        // do purchase    }}

Consider the code below. What is the output after it is run?  String x = “bumble”; String y = “bees”; y = y. toUpperCase(); x = y; y = x + y.charAt(3); System.out.println(y); 

A Java source code file is run on the JVM.

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

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”);

Write an equivalent lambda expression that implements the functional interface NE 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 RunningOutOfIdeas{ public static void main(String[] args) { RunningOutOfIdeas rooi = new RunningOutOfIdeas(); rooi.test(new NE() { public boolean ne(double d1, double d2) { return Math.abs(d1-d2) > 0.001; } }); } public void test(NE nEq) { nEq.ne(1.331, 1.332); }}interface NE { public boolean ne(double d1, double d2);} 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 below, what will be the value returned from the method invocation shown? public static int mystery(int a, int b) {   if (a == 5 || b == 5) {        return 1;    } else {       return b + mystery(a / 5, b * 2);    }} int value = mystery(625, 2);

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);
