For the given code below, which lines are valid (will compile and run)? Assume each line is run independently.   public class Robot {    private static boolean speed;    private int numWheels; public static double move() {          return 0.0;      }      public int rotate() {          return 0;      }      public static void main(String[] args) {        Robot obj = new Robot();        1 Robot.move();         2 Robot.rotate();         3 obj.move();         4 obj.rotate();                                    5 System.out.println(Robot.speed);         6 System.out.println(Robot.numWheels);          7 System.out.println(obj.speed);          8 System.out.println(obj.numWheels);  } }   1  : [1]   2  : [2]   3  : [3]   4  : [4]   5  : [5]   6  : [6]   7  : [7]   8  : [8]

For the given parent class, write a child class that satisfies the following requirements: child class is named your first name overrides the squish method in the child class overloads the grow method in the child class double instance variable named ripeness overrides the equals method from the Object class must use all instance fields to determine equality method signature can be of your choosing, if applicable, and you do not need to provide the method body for those two methods (i.e. only need { } ) you do not need to write any constructors, getters, or setters public class Berry { // override public void squish(int[] arr, char letter) { //method body } // overload public int grow(String type, int time) { //method body } }  Make sure to select the ‘Preformatted’ style from the dropdown so your code is formatted clearly.
